Matt , If your going to install that motor into your skid steer , while you have the empty Core , use it to fab your engine mounts, less weight to sling around ... Might have to re-install front cover for width of front mounts ..

If I had a theorize what might have happened to that engine, it started life normal ran tens of thousands of hours at that point a lower end bearing probably went bad. The engine was removed crank kit was put in and it was called good. Engine reinstalled ran another ten thousand hours probably with poor maintenance and shows on the crank bearings and rod bearings at that point the equipment was taken out of service and the engine was sold. Your seller sold the engine as a running motor and he should have sold it as core.
I have the same engine in a Takeuchi TL130 skid steer. It has an oil pan drain plug on the side. The manual shows different configurations for the oil pan. You should be able to find one. My TL130 was an auction buy (non runner). It turned out to have a spun rod bearing. A lot of metal in the engine. Replaced the crankshaft with a Chinese replacement. They are all made in China anyway. It looked like someone stripped the threads on the oil pan plug and it leaked and eventually was run without oil. It belonged to a bricklaying contractor so was used by different crews and no one took care of it. I just replaced the crankshaft and bad rod and cleaned it all out. It runs fine now except it blows white smoke sometimes. Seems to be mostly after sitting unused for a while. I should have rebuilt the head and replaced the valve guides. That engine is easy to work on. I had to put it together twice, the second time to replace the push rod that I bent putting the head back on and to replace the rear seal that I screwed up installing it. If I remember right, a piece of 3" PVC pipe works as a good tool to install the rear seal. I didn't discover that the first time around. Skid steers are a pain to work on because everything is packed into such a tight space.
Matt we both live in the same Metro area. We have very few Automotive Machine Shops left in the area and the ones left are aging out. Skills are being lost forever. It is part of the disposable society we now live in. Keep up the good work enjoy the videos.
I think that is indicative of most of the country. We used to have a half dozen good machine shops in our little rural area of Arkansas. That was because we fixed things. No more it seems, just throw it in the scrap bin and buy a new one.
@@Watchyn_Yarwood-Your comment is spot on! The thing most people don’t understand is that the item being thrown away is still a better unit after being fixed than a brand new one!
@@Watchyn_Yarwood Because it's cheaper to buy a new one. The cost of labor relative to the cost of goods is too high, so generally it's better to replace. My last 4 cylinder build was $3k in machine work and it was just basic stuff done by a mediocre shop. If it wasn't being done for race use it would make no sense to spend that, the complete motor is $3k, i was into it for $6500 when parts were added and i reused 3/4 of the old parts and built it myself.
I would have sent the engine back. I did enjoy the tear down though. Looking forward to next video. Thank you for taking the time to film this for us 👏🤞👍🙏
I would say that engine has done more than a thousand hours or very little to no maintenance, the good thing is we get another great video to watch. Matt wishing you and yours and Charlie a very happy Christmas from the UK
That is clearly lack of Maintenance no oil changes and no air filters that's the number one cause of engine failure. You're a better man than me I would demand my money back
100% no air filter. Did a service on my tractor with the same engine. Had a massive wildfire come towards my house and got in a hurry and forgot to put my new air filter in. Tractor made it 1 hour without the airfilter before it smoked the cylinders exactly the same as yours. I got lucky on the crank and bearings. Got 30 over pistons and had the block honed out to fit the new pistons.
@@djmips Doesn't take long at all. I race off road and a few years ago there was a race in a location where the dirt was like baby powder. We called it moon dust. Somewhere between 1/3 and 1/2 of the engines failed within 2 hours, and these are all using heavily oiled foam filters specific for off road race use. The ones that made it to the end still needed to be rebuilt. Whatever this dust was, it went right through the filters like nothing anyone had ever seen, and these are guys who regularly race in the desert. Even the factory race teams were blowing up left and right. There will never be another race held there, at least not by that organization.
You were schooling yourself as a mechanic the second you opened up an engine and kept going. 😊 I love your style of video. Explaining as you do the work and not wasting time. Love that. 😁
You are a great mechanic. Love your videos. You are my favorite fixing everything you have. Bulldozer then elevator. Now a skid steer. Just wow. Good man and great mechanic
Same here with 40+ years in the vehicle maintenance field. I think that engine was dusted. What else could have worn those cylinders like that and still have decent bearings?
I have on one of my motors. The factory used low tension rings for fuel economy and i ran 35psi of boost (on gasoline not a diesel) and regularly did long pulls. The heat took the remaining tension out the rings and they no longer sealed. Engine looked brand new but had a bunch of blowby solely because of the ring tension.
If it’s from the southeast, we have hard water: the white chalky stuff could be calcium/lime where the service person used tap water for coolant (particularly where a coolant leak was persisting, using hard water can exacerbate the problem)
I’m tempted to by an engine to rebuild it and film it. Then we’ll all see what “I’m not a mechanic” looks like 😂. Great video! Looking forward to the next one!
What a disappointment. I worked in a wreckers for years. All our second hand engines were hot run and comp tested before we sold them. If the comp was low we rebuilt or scrapped.. still it’ll make for some interesting videos! Merry Xmas! 🇦🇺🍺🍺
Great video, cool you took the time to diagnose it fully. As an aside, in your final "scene" I noticed the beams in your shop are monstrously large. Have you considered making a Unistrut trolley bridge crane between them? 600lbs capacity should be easy and 1200 not too hard. Over head lifts just seem so useful, especially as you get older.
Matt, Mud Daubers plug every 1/4" hole on the East Coast in everything possible. I live in PA, and every hole in my Dewalt blower, the cooking Grill, and the ground holes in outside receptacles are plugged.
Lifelong Utah resident (St. George till age 22, then Provo-American Fork.) Mud daubers or hard water were my first thoughts when I saw the dirt in the holes. Both are very common.
They don't boil blocks. They put the block in a oven and cook it. All the oils and grease gets cooked and turns to ash. Next the block goes into a shot peening machine for a few hours until the block comes out newish.
@@Firecul You can get brand new motors delivered free within 10 days for only 4400. Putting any more money and a lot more time in that "dusted" old motor seems like a waste. It needs a lot of work.
@@snappingbear I think getting engine rebuilt will be a lot cheaper than 4400 and putting it together yourself means you know exactly how to take it apart and diagnose the issue way easier if something goes wrong. Also he didnt put any money into it yet the shop reimbursed him
Brother bathe and blow that block well before assembly, be sure to buy a new oil pump and o-rings around it and take it easy wrenching around aluminium...love your content...
You have such a great outlook and I am glad that you are getting reimbursed! I would say you qualify as a mechanic and probably better than most who do it for a living. I am looking forward to following the project.
It's in case they screw up as so many commenters are so quick to jump on people's arses the second they do something they deem as in correct followed by "" Call yourself a Mechanic "" followed by their insults. It's a good way to cover their backsides. .

Matt, you are totally a mechanic as you rebuilt the cat and redoing your excavator. You do well above what is required along with care you show it what you do. Keep up the great work.
Bummer for sure - I think with equipment like this the air cleaner came apart, and the thing was just run, and run, making "pay-dirt" until it wouldn't start. Great diagnosis, and very true about machining and master machinists getting harder and harder to come by. Great video editing to! Thank you for sharing ...
Very well explained why you made the choice of what engine to go with . I wish you luck my friend on getting the machine completed and using it to complete the work you have planned !
Very Interesting! Usually you see some oil starvation issues with totally grenaded internals on yt, very interesting to see what a bunch of dirt does. When I saw that piston wiggling around, my first though was - that thing ran??? Guess I never saw a video of a dirt-filled engine :) I totally understand you wanting to take it apart, even though its clearly dead. I would have done the same on a free, dead engine.
Dude, you are amazing and inspiring! I rebuilt a VW 1.6 liter diesel and the little truck it came in. Took my time and tried to do everything right, but it was disappointing. Aluminum head was linebored for camshaft with oversized bearing journals, but sent back to me with std camshaft. Couldn't maintain oil pressure because the oil was escaping at the cam bearings. Sent the head back and it returned with inadequate valve relief, so deck height measurement and proper head gasket thickness still resulted in valves striking pistons. Got a 3rd head from the rebuilder and drove the little truck a few months - then a Kia pulled out in front of me and totalled it...... A lot of disappointment in that one. I admire the way you handle disappointment.
Matt, you have way more patience than me! If someone sells you a “good” engine you get a good engine ! Or that engine goes through their window . Keep up the wholesome work!
"I guess we are looking at a full rebuild" - this seems to be the way all your purchases are going. We all love your meticulousness and attention to detail so notentirely surprising for the viewers ;-) Maybe you should consider buying that crankshaft grinding tool that the shop had no-one to operate, this might not be the last engine you see that needs work. Also then you can add "I'm not a machinist" to your "I'm not a mechanic" tag-line
Many comments say they would have sent this engine back. But at least you get to do more channel content - And you finish up with an engine you can be totally confident about.
Sorry you didn’t get what you paid for. Good that the seller is doing right by you. Great that you are going to make more videos! May be good thing with winter coming on, although still pretty stoked about the excavator going back together. Love you videos regardless of what you happen to be working on!
That crank must absolutely be ground! You definitely got shafted on this one. Someone did a bearing roll on it a 1000 hours ago, but that engine has probably has many times more hours on it.
The white / tan dust you were digging out of the round holes are Mud Dauber Wasp Nests there is a larva in each hole. Sorry, this happened to you, but you will make the engine better than new. JeffinMaine
Wow - I was glued to the screen to see the damage and the cause... A filter... “For want of a nail the shoe was lost. For want of a shoe the horse was lost. For want of a horse the rider was lost. For want of a rider the battle was lost". A Mother Goose poem... For lack of a filter the engine was lost. Thankfully we didn't loose the tractor or, more importantly, the rider! Unbelievable that someone would operate an engine without changing the air filter. Thorough video - thanks Man...
Another superb video!! I have great respect for your lack of anger/irritation when you discover how fouled up this engine was. Best wishes for a Merry Xmas to you and your family.
Well another great analysis with outstanding performance of perfection ! Was really wanting a quick running engine for your swap but at least it’s going to end up really good . Thanks for taking the time to post your endeavors matt . Keep up the great work ! 👍👍👍👍
It's the same in this area there isn't any engine rebuilt shops any longer they have all closed, with the price of parts and labor it seems it worthwhile
You have way more patience and understanding than I have. I’d have had that seller packing another engine to send me and he’d pay the freight again. IMO he knew what he sold you was trash. You have the patience of Job!
That thing should be advertised as "rebuildable core", some edges look more like 10k hrs, not 1k hrs... Glad you got some money back, so good luck on rebuilding it, at least the parts doesn't seem to be made of unobtainium... 😮👍👍
If it's the seller suggested above, it was a 'broker' that scrapes local engine ads and lists the engines on eBay at much higher prices, claiming lower hours and better condition than the original seller was stating.
In my youth I made the mistake of running my car without an air filter, with similar results. The bore ovality could be measured with a tape measure. Curiously, it still ran OK but it only did about 100 miles to the gallon - of oil!
What a bummer. At least we all are now more knowledgeable in what happens when you let a diesel engine run without a air cleaner for a long time. Honestly I was expecting lot of shrapnel in the oil pan but only metal paste came out. Yanmar diesel parts should be plenty available. Any line boring job will be just a huge expense unless its one of a kind engine that has no analogs. Probably the Yanmar had the factory silicone that is very strong unlike the one they sell in the stores. In terms of entertainment and teaching 10/10 for the video
I found out the hard way. I ran the top of the line KN air filter.😂😂 When I pulled the intake off. The runners were caked with a very fine dust paste consistency. The fine dust got mixed with the KN air filter red oil. It got my mass air flow sensor dirty. Then my throttle body. I tore the engine down and sent it to the builder and got it rebuilt. While the engine was at the shop. I took my parts and poured dish washing soap in the intake manifold. I fired up my pressure washer and started washing it out. I saw black oil coming out of the runners. I will never run KN air filter in my vehicle ever again. To add proof it's a bad filter, There is a fella that tested a bunch of different filters. Flow, tested how much dirt each filter would trap. KN failed.
@@2nickles647 If someone would have shown me Matts pistons and sleeves I would have said at least 3000h plus machine. Just the fact it ran so much dirty air in shortened the life significantly. KN air filters are meant for very specific applications and not everywhere. Seen these on machines that work in dirt or in high dust environments. Well that is a recipe for a disaster to come.

Matt, sorry you got a dead engine...shame on the seller. All your subs are anxious to see you work in the excavator. With the great job you are doing on it so far, it will be better than new when you are done. Love your channel and great videos. Looking forward to see that lousy engine get rebuilt and installed in your skid steer. BTW you are a great mechanic. Few mechanics would take the time and be so meticulous as you.
For a guy who is 'not a mechanic', you know your way around engines. Plus you even probed deeply the fit issues, which are complex -- using your noggin'! You will end up with a rebuilt engine -- very nice.
If you look at the inlet port its bias to the rear of the engine (flywheel end) many years ago (around 2008) a well known forklift manufacturer who sold brands beginning with "H" and "Y" had problems with the air filters made by a company beginning with a "D" not sealing correctly. As a consequence unfiltered air wore out the cylinders, with No's 3 & 4 being the most affected.. Company "D" made changes to the thickness of the seal at the end of the air filter as well as making a change to the filter housing cap to prevent the filter not being seated fully and the problem went away.. Many engines were wiped out before the changes were made..
Matt sorry for responding to this video so late, I do believe that is a marine application yanmar engine that is why you are seeing all the electrolyte in the open screw holes, it's a very worn out engine lots of ideling very common in marine applications Good luck with this one
This one was almost too familiar... I was swapping a Yanmar 4TNV98T on a Takuchi TL240. Found a "Good running" Used engine. Completed the swap only to find No Start. This engine utilizes an ECM to control the fuel rack on the injection pump. After 2 Takuchi mechanics failed to flash the ecm or diagnose the problem I dug a little deeper and discovered the injection pump was tampered with and no longer was in time, the 4 bolts the manual explicitly says do not touch were definitely touched. Further proving my hypothesis that the engine never ran. Buyer beware on used engines you have not seen run with your own eyes. Currently timed and installed the original injection pump and waiting for an adapter cable from china to hopefully be able to flash the ecm with the correct perimeters for the fuel rack actuator. Going to stick with mechanical engines from now on. Best of luck on your Swap I will be following along.
This thing definitely looks like it has a damaged\missing air filter, especially with how it wrecked the #1 & 2 cylinders more than the 4th which is further away from intake! Thats a lot if cylinder wear for sure! I find it hard to believe it started without oil being dumped onto the pistons & shot with cosby sauce to get it to start! You're taking this way better than I would be, for sure. I'd be a lil furious with this seller but atleast he's taking care of the sutuation and you get to install a freshly rebuilt motor you know is in great shape now....and some extra content! Anyways, I love you saying "I'm not a mechanic", while you may not be a professional mechanic for a living you do a great job pretending to be one on 'TV'! You are always so very thorough with your rebuilding projects I think you can add part time mechanic\technician to your resùmé for future reference! Love the content, keep it up Matt! Happy holidays to you & family(Charlie included)🐾!🎅🏻☃️🎁🎄🛠️👍🏻👌🏻🔧🔩
46:47 Let me get my 'Yanmar ring gap measurer' Get a Stanley fat max out with eighth inch scale measurements - we don't need no precision measuring devices(feeler gauge) here when you can throw a hotdog down this hallway without touching the sides!😂😂📏🌭
I just got done rebuilding a Perkins, for an 1980s cat forklift, the person picked it up for pennies, however when we took the engine apart that the engine had a fresh rebuild, and very low hours, but what we did find was three broken pistons nothing metal got in to the bottom end, but but three of the pistons were totally destroyed, it even distorted the top half inch of liner, came to the conclusion that they tried to start it with either or some accidently put gas in it , the owner of this forklift thinks it was either
Look at the centre camshaft bearing boss. It’s got an oil groove in it so double check if there should be a bearing bush installed there. I was wondering what you’d do with a block with such worn out cylinders. I didn’t know you could get cylinder sleeves for them. Great to hear you’ll get a brand new rebuilt engine in the end 👍
I'm glad and impressed that you see it as a fairly even win in the end. Even though rebuilding engines can be fun I'd sure be tired of having to rebuild an engine that ideally should've been a drop in n go.
Superb tear-down and analysis. Running without an air filter and not changing oil at specified intervals is destructive. I hope you get reimbursed for your work. Cheers! Will be looking for more of your videos.
Dude, you might not have a Mechanic qualification or ticket, but you know a damned sight more and are much more adept at the job than half the guys in the trade nowadays. Fair play to you ripping in to this engine. I'd have got as far as the compression test and sent the thing back. I believe my kids would call that "Rage Quitting"! That engine was obviously run by a guy who just didn't care about day to day maintenance. I know by your method you are going to get a reliable, freshly remanufactured engine and you have time on your side to do it, but most dudes would want less of a headache and to chuck in a running engine and have done with it. I guarantee there's thousands of projects like this gathering dust in shops across the country where the owners just lost interest when faced with the amount of work & time required?
Your forensic analysis and conclusions are pretty good. I agree with your assessment in part. I also think that the engine was run many hours without an oil change. Then the lower bearings were all replaced and run for a very short while until it was removed and sold to the shop you purchased it from. Just my swag...
You have way more patience (and understanding) than I would. I would be on phone asking for another engine. AND I would say you're selling yourself short by saying you're NOT a mechanic
At the point when you removed the valve train you can push air into the cylinders with a blow gun simulating a leak down test , just to hear where the air pressure is going, i,e intake, exhaust, water jackets, crankcase.
Matt: "I'm not a mechanic..."
Proceeds to to tear into the engine like he's done it for 50 years...

Been an equipment mechanic for over a decade, never seen pistons drop out like that.
Same here with 40+ years in the vehicle maintenance field. I think that engine was dusted. What else could have worn those cylinders like that and still have decent bearings?
I have on one of my motors. The factory used low tension rings for fuel economy and i ran 35psi of boost (on gasoline not a diesel) and regularly did long pulls. The heat took the remaining tension out the rings and they no longer sealed. Engine looked brand new but had a bunch of blowby solely because of the ring tension.
Agree I think dusted for sure.
If it’s from the southeast, we have hard water: the white chalky stuff could be calcium/lime where the service person used tap water for coolant (particularly where a coolant leak was persisting, using hard water can exacerbate the problem)
That was from mud dauber wasps. At least in the bolt holes.
I’m tempted to by an engine to rebuild it and film it. Then we’ll all see what “I’m not a mechanic” looks like 😂. Great video! Looking forward to the next one!
Don't know what you do for a living but you are a very good mechanic. Enjoy you videos.
What a disappointment. I worked in a wreckers for years. All our second hand engines were hot run and comp tested before we sold them. If the comp was low we rebuilt or scrapped.. still it’ll make for some interesting videos!
Merry Xmas! 🇦🇺🍺🍺
If the oil looks like wet JB Weld then you are going to have a bad day :)
Great video, cool you took the time to diagnose it fully. As an aside, in your final "scene" I noticed the beams in your shop are monstrously large. Have you considered making a Unistrut trolley bridge crane between them? 600lbs capacity should be easy and 1200 not too hard. Over head lifts just seem so useful, especially as you get older.
the original plan was to move the gantry from the excavator into the shop, but I don't know if it will survive
Matt, Mud Daubers plug every 1/4" hole on the East Coast in everything possible. I live in PA, and every hole in my Dewalt blower, the cooking Grill, and the ground holes in outside receptacles are plugged.
your not east coast your north east I am coast the Atlantic ocean is my back yard
Great job as always Matt keep it
Lifelong Utah resident (St. George till age 22, then Provo-American Fork.) Mud daubers or hard water were my first thoughts when I saw the dirt in the holes. Both are very common.
beside the work you stated, i would suggest you also have the block boiled, new freeze plugs and cam bearing install at the machine shop
Why waste any money on it?
@@snappingbear With all the work that is already being done for this I'd want to make sure every last bit of all that sludge was gone
They don't boil blocks.
They put the block in a oven and cook it. All the oils and grease gets cooked and turns to ash.
Next the block goes into a shot peening machine for a few hours until the block comes out newish.
@@Firecul You can get brand new motors delivered free within 10 days for only 4400. Putting any more money and a lot more time in that "dusted" old motor seems like a waste. It needs a lot of work.
@@snappingbear I think getting engine rebuilt will be a lot cheaper than 4400 and putting it together yourself means you know exactly how to take it apart and diagnose the issue way easier if something goes wrong. Also he didnt put any money into it yet the shop reimbursed him
Brother bathe and blow that block well before assembly, be sure to buy a new oil pump and o-rings around it and take it easy wrenching around aluminium...love your content...
You have such a great outlook and I am glad that you are getting reimbursed! I would say you qualify as a mechanic and probably better than most who do it for a living. I am looking forward to following the project.
I'm not a mechanic he said lol, and I'm not an air breather lol. If your not a mechanic I don't know who is.
Exactly what I was thinking! 😂
Came here to say the exact same thing
that's funny, I hear a lot of UA-camrs say that, I'm not a mechanic, but they're doing mechanic stuff, and they know as much as mechanics know.. lol..
It's in case they screw up as so many commenters are so quick to jump on people's arses the second they do something they deem as in correct followed by "" Call yourself a Mechanic "" followed by their insults. It's a good way to cover their backsides. .
If he says he's not a mechanic, then that's because he's not a mechanic. There's no word trickery, or digging for some hidden message here...he's simply stating a clear and precise fact that he isn't a mechanic. Accept that and move on. Just because I can teach my child something, that doesn't make me a "teacher" as the common meaning of the word implies.
You really impressed me when you stated you're not a mechanic. Your knowledge exceeds quite a few mechanics that I've known.
I strongly disagree with one of your assessments: "I am not a mechanic" You might not do this for a living, but you are a very skilled machine technician/mechanic.

@@cliffbracken6422triggered much! You copy & post same thing to several commenters. Wow🤦🏻♂️
I just love your ‘can do’ attitude. It is really refreshing 🇬🇧😊
Matt, You do a great job editing, and your explanations are thorough and easy to understand. Keep them coming!
That ridge is massive. worn out, patched up and run for a bit, I can't wait to see the valves.
Man, you have more patience than me, I would of sent that engine back as soon as it measured no compression with no stuck valves lol
You always have such a great attitude, no matter what you come across. And you definitely wrench and speak like a professional mechanic Matt.
Matt, you are totally a mechanic as you rebuilt the cat and redoing your excavator. You do well above what is required along with care you show it what you do. Keep up the great work.
Bummer for sure - I think with equipment like this the air cleaner came apart, and the thing was just run, and run, making "pay-dirt" until it wouldn't start. Great diagnosis, and very true about machining and master machinists getting harder and harder to come by. Great video editing to! Thank you for sharing ...
That engine was definitely dusted...IMO
Very well explained why you made the choice of what engine to go with . I wish you luck my friend on getting the machine completed and using it to complete the work you have planned !
Very Interesting! Usually you see some oil starvation issues with totally grenaded internals on yt, very interesting to see what a bunch of dirt does. When I saw that piston wiggling around, my first though was - that thing ran??? Guess I never saw a video of a dirt-filled engine :)
I totally understand you wanting to take it apart, even though its clearly dead. I would have done the same on a free, dead engine.
Thanks Matt. Merry Christmas
Thanks Matt, really enjoyed your video. Your camera, lighting and editing skills are superb. 😊
Dude, you are amazing and inspiring!
I rebuilt a VW 1.6 liter diesel and the little truck it came in. Took my time and tried to do everything right, but it was disappointing. Aluminum head was linebored for camshaft with oversized bearing journals, but sent back to me with std camshaft. Couldn't maintain oil pressure because the oil was escaping at the cam bearings. Sent the head back and it returned with inadequate valve relief, so deck height measurement and proper head gasket thickness still resulted in valves striking pistons. Got a 3rd head from the rebuilder and drove the little truck a few months - then a Kia pulled out in front of me and totalled it...... A lot of disappointment in that one. I admire the way you handle disappointment.
I’m from the northwest and now live in Florida, I thoroughly enjoy your channel, and your optimistic attitude, keep up the good work.
Matt, you have way more patience than me! If someone sells you a “good” engine you get a good engine ! Or that engine goes through their window . Keep up the wholesome work!
"I guess we are looking at a full rebuild" - this seems to be the way all your purchases are going. We all love your meticulousness and attention to detail so notentirely surprising for the viewers ;-)
Maybe you should consider buying that crankshaft grinding tool that the shop had no-one to operate, this might not be the last engine you see that needs work. Also then you can add "I'm not a machinist" to your "I'm not a mechanic" tag-line
Many comments say they would have sent this engine back. But at least you get to do more channel content - And you finish up with an engine you can be totally confident about.
A comprehensive analysis, yet again. Always fascinating seeing what you turn up.
Sorry you didn’t get what you paid for. Good that the seller is doing right by you. Great that you are going to make more videos! May be good thing with winter coming on, although still pretty stoked about the excavator going back together. Love you videos regardless of what you happen to be working on!
That crank must absolutely be ground! You definitely got shafted on this one. Someone did a bearing roll on it a 1000 hours ago, but that engine has probably has many times more hours on it.
You're so brave. I'd check compression and say "screw that! give me back my money"
The white / tan dust you were digging out of the round holes are Mud Dauber Wasp Nests there is a larva in each hole. Sorry, this happened to you, but you will make the engine better than new. JeffinMaine
Thanks
Wow - I was glued to the screen to see the damage and the cause...
A filter...
“For want of a nail the shoe was lost. For want of a shoe the horse was lost. For want of a horse the rider was lost. For want of a rider the battle was lost". A Mother Goose poem...
For lack of a filter the engine was lost. Thankfully we didn't loose the tractor or, more importantly, the rider!
Unbelievable that someone would operate an engine without changing the air filter.
Thorough video - thanks Man...
Yanmar is one of my favourite engines . I have a JD 655 and 955 compact tractor , both with Yanmar power . I think you made the right choice .
Another superb video!! I have great respect for your lack of anger/irritation when you discover how fouled up this engine was.
Best wishes for a Merry Xmas to you and your family.
I'm no mechanic but!
Your more of a mechanic than most professional Mechanics!!!!
Dude you have earned my respect........
What's next? 👍
Well another great analysis with outstanding performance of perfection !
Was really wanting a quick running engine for your swap but at least it’s going to end up really good .
Thanks for taking the time to post your endeavors matt .
Keep up the great work ! 👍👍👍👍
Thanks!
Thanks Michael!
as a novice mechanic realy appreciated the way you did the engine autopsy
It's the same in this area there isn't any engine rebuilt shops any longer they have all closed, with the price of parts and labor it seems it worthwhile
I really appreciate all the reasoning and explaining you did at the end. I learned a lot and was interesting to hear all that.
You have way more patience and understanding than I have. I’d have had that seller packing another engine to send me and he’d pay the freight again. IMO he knew what he sold you was trash. You have the patience of Job!
I never clicked so fast mate keep em coming
You're giving me the confidence to attempt my own rebuild :)
Thanks for the Content
Thank you!!!
Matt I would freak out!! You are one positive person! More videos for us!! Thanks for sharing congratulations on passing the 100k
That thing should be advertised as "rebuildable core", some edges look more like 10k hrs, not 1k hrs...
Glad you got some money back, so good luck on rebuilding it, at least the parts doesn't seem to be made of unobtainium...
😮👍👍
If it's the seller suggested above, it was a 'broker' that scrapes local engine ads and lists the engines on eBay at much higher prices, claiming lower hours and better condition than the original seller was stating.
I was like the bolts on top and bottom. I was there for that struggle ive done a lot with all the styles of engines you listed.
In my youth I made the mistake of running my car without an air filter, with similar results. The bore ovality could be measured with a tape measure. Curiously, it still ran OK but it only did about 100 miles to the gallon - of oil!
What a bummer. At least we all are now more knowledgeable in what happens when you let a diesel engine run without a air cleaner for a long time. Honestly I was expecting lot of shrapnel in the oil pan but only metal paste came out. Yanmar diesel parts should be plenty available. Any line boring job will be just a huge expense unless its one of a kind engine that has no analogs. Probably the Yanmar had the factory silicone that is very strong unlike the one they sell in the stores. In terms of entertainment and teaching 10/10 for the video
I found out the hard way.
I ran the top of the line KN air filter.😂😂
When I pulled the intake off.
The runners were caked with a very fine dust paste consistency.
The fine dust got mixed with the KN air filter red oil.
It got my mass air flow sensor dirty. Then my throttle body.
I tore the engine down and sent it to the builder and got it rebuilt.
While the engine was at the shop. I took my parts and poured dish washing soap in the intake manifold. I fired up my pressure washer and started washing it out. I saw black oil coming out of the runners.
I will never run KN air filter in my vehicle ever again.
To add proof it's a bad filter,
There is a fella that tested a bunch of different filters.
Flow, tested how much dirt each filter would trap. KN failed.
@@2nickles647 If someone would have shown me Matts pistons and sleeves I would have said at least 3000h plus machine. Just the fact it ran so much dirty air in shortened the life significantly. KN air filters are meant for very specific applications and not everywhere. Seen these on machines that work in dirt or in high dust environments. Well that is a recipe for a disaster to come.
Matt, sorry you got a dead engine...shame on the seller. All your subs are anxious to see you work in the excavator. With the great job you are doing on it so far, it will be better than new when you are done. Love your channel and great videos. Looking forward to see that lousy engine get rebuilt and installed in your skid steer. BTW you are a great mechanic. Few mechanics would take the time and be so meticulous as you.
For a guy who is 'not a mechanic', you know your way around engines. Plus you even probed deeply the fit issues, which are complex -- using your noggin'! You will end up with a rebuilt engine -- very nice.
Great video thanks for putting it all together!
Something relaxing about wrenching videos. I had a crappy day today. This video makes the day more chill for me
If you look at the inlet port its bias to the rear of the engine (flywheel end) many years ago (around 2008) a well known forklift manufacturer who sold brands beginning with "H" and "Y" had problems with the air filters made by a company beginning with a "D" not sealing correctly.
As a consequence unfiltered air wore out the cylinders, with No's 3 & 4 being the most affected.. Company "D" made changes to the thickness of the seal at the end of the air filter as well as making a change to the filter housing cap to prevent the filter not being seated fully and the problem went away..
Many engines were wiped out before the changes were made..
Will probably never ever every rebuild an engine, but I still find these videos interesting 😂
I do not know how you keep track of everything in your shop! Great video.
Awesome work there, Matt! That's a really simple engine to work on and I think, once done, it will give you excellent service. Keep up the good work!
Looking at the positives and learning opportunities from a bad situation, love the attitude
YAYY finally update on the skidsteer ^_^
Matt sorry for responding to this video so late, I do believe that is a marine application yanmar engine that is why you are seeing all the electrolyte in the open screw holes, it's a very worn out engine lots of ideling very common in marine applications
Good luck with this one
This one was almost too familiar... I was swapping a Yanmar 4TNV98T on a Takuchi TL240. Found a "Good running" Used engine. Completed the swap only to find No Start. This engine utilizes an ECM to control the fuel rack on the injection pump. After 2 Takuchi mechanics failed to flash the ecm or diagnose the problem I dug a little deeper and discovered the injection pump was tampered with and no longer was in time, the 4 bolts the manual explicitly says do not touch were definitely touched. Further proving my hypothesis that the engine never ran. Buyer beware on used engines you have not seen run with your own eyes. Currently timed and installed the original injection pump and waiting for an adapter cable from china to hopefully be able to flash the ecm with the correct perimeters for the fuel rack actuator. Going to stick with mechanical engines from now on. Best of luck on your Swap I will be following along.
those yanmars are the best!! i love all the tnv70 series......i just started watching....i hope it runs...i guess ill see
well dang that sucks man well at least you got to make a cool interesting video out of it so thats good
*- The white "corrosion" deposits at **33:58** that you ask about is what I would call "hard water" mineral deposits such as calcium and magnesium.*
Or, possibly, the dried tears of the previous owner?
@@misanthropicprincipal9094
🤣
salt...east coast its overused
You´re doing some amazing stuff! Watching You, Squatch, Mustie etc wants me wanna get off my couch, but then I would miss your youtube updates 🙂
This thing definitely looks like it has a damaged\missing air filter, especially with how it wrecked the #1 & 2 cylinders more than the 4th which is further away from intake! Thats a lot if cylinder wear for sure! I find it hard to believe it started without oil being dumped onto the pistons & shot with cosby sauce to get it to start! You're taking this way better than I would be, for sure. I'd be a lil furious with this seller but atleast he's taking care of the sutuation and you get to install a freshly rebuilt motor you know is in great shape now....and some extra content!
Anyways, I love you saying "I'm not a mechanic", while you may not be a professional mechanic for a living you do a great job pretending to be one on 'TV'! You are always so very thorough with your rebuilding projects I think you can add part time mechanic\technician to your resùmé for future reference! Love the content, keep it up Matt! Happy holidays to you & family(Charlie included)🐾!🎅🏻☃️🎁🎄🛠️👍🏻👌🏻🔧🔩
46:47 Let me get my 'Yanmar ring gap measurer'
Get a Stanley fat max out with eighth inch scale measurements - we don't need no precision measuring devices(feeler gauge) here when you can throw a hotdog down this hallway without touching the sides!😂😂📏🌭
Should have sent it back when you found no compression
I just got done rebuilding a Perkins, for an 1980s cat forklift, the person picked it up for pennies, however when we took the engine apart that the engine had a fresh rebuild, and very low hours, but what we did find was three broken pistons nothing metal got in to the bottom end, but but three of the pistons were totally destroyed, it even distorted the top half inch of liner, came to the conclusion that they tried to start it with either or some accidently put gas in it , the owner of this forklift thinks it was either
Look at the centre camshaft bearing boss. It’s got an oil groove in it so double check if there should be a bearing bush installed there. I was wondering what you’d do with a block with such worn out cylinders. I didn’t know you could get cylinder sleeves for them. Great to hear you’ll get a brand new rebuilt engine in the end 👍
I'm glad and impressed that you see it as a fairly even win in the end. Even though rebuilding engines can be fun I'd sure be tired of having to rebuild an engine that ideally should've been a drop in n go.
Send all your machining to those JAMSI guys. That’d be a cool collab. Those guys seem like some nice honest guys.
I agree Colorado isn't that far away from him!
Superb tear-down and analysis. Running without an air filter and not changing oil at specified intervals is destructive. I hope you get reimbursed for your work. Cheers! Will be looking for more of your videos.
Too bad it didn't work out - glad you were made whole on it - Merry Christmas.
Dude, you might not have a Mechanic qualification or ticket, but you know a damned sight more and are much more adept at the job than half the guys in the trade nowadays.
Fair play to you ripping in to this engine. I'd have got as far as the compression test and sent the thing back. I believe my kids would call that "Rage Quitting"!
That engine was obviously run by a guy who just didn't care about day to day maintenance.
I know by your method you are going to get a reliable, freshly remanufactured engine and you have time on your side to do it, but most dudes would want less of a headache and to chuck in a running engine and have done with it.
I guarantee there's thousands of projects like this gathering dust in shops across the country where the owners just lost interest when faced with the amount of work & time required?
תודה!
Many thanks!
Your forensic analysis and conclusions are pretty good. I agree with your assessment in part. I also think that the engine was run many hours without an oil change. Then the lower bearings were all replaced and run for a very short while until it was removed and sold to the shop you purchased it from. Just my swag...
Fascinating to see a blown engine reverse analysis of the failure cause.
You have way more patience (and understanding) than I would. I would be on phone asking for another engine. AND I would say you're selling yourself short by saying you're NOT a mechanic
At the point when you removed the valve train you can push air into the cylinders with a blow gun simulating a leak down test , just to hear where the air pressure is going, i,e intake, exhaust, water jackets, crankcase.
