- Rebuilding the engine that got water logged in a hurricane then someone tried to start it with water in the cylinders and bent a rod. Then to top that off they removed the head and let it sit in the elements opened up for years and seized the engine . Two afternoons and i got this this back together and tried to start.
Part 1 of the video • Yanmar boat engine
Update on the yanmar diesel... This diesel was flooded on the engine room of a sailing catamaran during a hurricane with a previous owner, Scott and I have rescued 7 buses together and Scott was kind enough to offer to give it a go on repairing the yanmar... The previous owner had taken the engine apart and fresh water had done a good job of making an added mess of everything...
Scott is really amazing at being able to go with the flow and figure ways to get most anything done...and done well...
The update is that we now have put over 600 hours on that engine this past charter season and it's running better than the one that was perfect in the other hull.... Thanks again Scott...
I am continually amazed at the conditions you are working in. In 1959, I rebuilt a 1949 overheated Chevrolet six (I don't remember the displacement) that had set in the Arizona desert for several years. Bored out.060 over it was a powerhouse for the time. It had shims and plastic tell-tales for clearance on the main and rod bears. I had to turn it over with a breaker bar many times before it would crank and it ran hot for several miles before the bearings "cured".
I just did this as a favor for a friend. It was more of a challenge. I have never once worked on a 4 stroke diesel ever. And since someone else took it apart and it was missing some parts it was crazy that we got it running in two afternoons.
It's always fun putting something back together that you didn't take apart! Excellent work Scott!
Gentleman,
I have to disagree with your opinion that Scot is a grade A mechanic. Not even close. My dad was Navy boilermaker for 20 years so I got to know quite a few people at Charlestown Navy Yard and when they had a mechanical problem they couldn't figure out they called on an old timer who should have retired years earlier but they kept him on for his expertise.
You Scott are the first mechanic I've seen and gotten to know equal to the old " CHIEF MASTER MECHANIC "
You are hereby promoted to Chief Master Mechanic.
You have never seen an engine you couldn't fix!
Cheers!
Once again, fantastic work, thanks for posting this. WD40 starting fluid, I love it! Speaks volumes for the build quality of Yanmar diesel engines! Those battery powered ratchet wrenches are sure less restrictive then the air powered versions I began using 40 yrs ago. No air hose to get in the way. I am surprised that the fuel pump and injectors worked after suffering water ingestion. That boat owner was lucky to have found you, but he looks like the same guy in the MCI bus video with the snapped pinion, so I guess he already had your number.
ua-cam.com/video/zuXHqdS26aA/v-deo.html yes i did this as a favor for a great bus client and friend. He has owned like 10 buses.
And yes, Wd is much less volatile than starting fluid. It took a bit to get fuel to the injectors
Probably the cleanest I've seen your hands in 50+ videos! Nice job getting it back running!
lol the chain next to the crank had me nervous!
Me too once i saw it... i was like shut it off right at the end saying “chain”
Sounds great. I love hearing an odd motor come to life after years of dormancy. Went from a pile of rusted parts into a useful power plant.
Very nicely done!! Shame on the Yanmar guy for not getting you the gaskets you needed. I also have a metric adjustable, -it doubles as a hammer!! Kudos to all the work you do man.
We have a John Deere L125 powered by a Isuzu diesel. It hasn't run in years. Parked it long ago and never went back to it. It isn't rusty like this was. This video inspired us to try the Isuzu again!
I had that same ring compressor for years, I came across one with 3 bands instead of 2, way better! Have rebuilt alot of engines on top of pallets...keep up the good work!
I'm putting the same motor in a excavator pulled it off a reefer. I have to swap most of the accessories but easy to work on.
You do great work in very austere conditions at times! Thank goodness for your metric adjustable! Fun to watch your videos!
I am kind of the opposite of you in regards to the contents of the toolbox. I have all metric tools and then a few standard sizes for the in between ones. 5/16" = 8mm, 7/16" = 11mm, 1/2" = 13mm and so on. So I keep standard wrenches and sockets for things that don't fit a metric size well.
Really cool to see that old Yanmar up and running. Great fix.
Yanmar 3GM 30F in my boat. One liter per hour cruise speed six knots from 24 HP. Mechanical governor no electronics.
I can watch a "Boss" all day long! You do great work.
Another success. Great work as always. Really enjoy watching you work, proves that you shouldn't give up on something until you've explored all possibilities. That conrod is one for the 'museum of sacrificed parts'. I kept repeating 00.00-0020 looking at the Roadking in the background, From what I can see of that one I'm running the same model here in the UK. How about a very quick walkround video just to scratch my V twin itch.I know it's not a bus or diesel but it is classic iron.
I use to love the feel of rebuilding a motor. Hearing it fire for the first time and that grin know yep I did that. Have a few cars in the back yard and a motorcycle finding the time is the hard part.
Top job , well done . You're a Grade A mechanic!
Rapidly getting to be my favorite channel!
Three new bus repair adventures coming this week
Having fun on this side
Good job. Some of your crew doesn’t wear shoes around the garage...be careful. Love it when a plan comes together.
That’s the boat owner - client.
I love your videos and I've discovered that I am a gearhead at heart. I think I heard you say that this is one of two engines on the craft. If so, all is well. I wouldn't plan a long cruise with that engine. With the lifters in such rusty shape, I am sure the camshaft will be toast in short order.
I hope you pulled the water pump cover and looked at the rubber impeller for missing paddles. It is a good idea to replace them anyway. If there are any missing paddles you need to look at the heat exchanger down stream of the water pump and rod it out if you see anything in it...Common cause of over-heating on a Yanmar.
All the little yanmars I’ve seen had valve buttons on them. I didn’t see you put them on. Thanks
Awesome dude 👍🏻 Love your simple way you explain what your doing so I can understand it......😄 Cheers for making great videos Stevie 🇬🇧
Your channel is well done, and the camera man gets good angles and close-ups. When you were assembling the first piston,I was worried about the ring-gap being much too large. In your next videos, could you please remember to do more "thinking out loud" so our questions might be answered immediately?
Subscribed!
You must have an Lydian or a man from Kentucky working with you. Just kidding love all your vids. Thanks
No glow plugs so injection timing is advanced during a cold start by having full throttle applied.
Great work! That seems to be really old school engine but most japanese are, obviously...
I put the 4 cylinder non marine version of this engine into a 3rd gen firebird. Yanmars kick ass.
Nice work! You rebuilt that rusted and seized boat anchor with minimal replacement parts. What was it? 2 connecting rods, a bearing and ring set, and a head gasket? The rest was just carefully cleaning and refurbishing what came off of it. That's an excellent rebuild! Thanks to the heroic metric crescent wrench! ;)
Very nice work!
I didn’t see the valve rotator buttons go in. I hope they didn’t get lost when they took it apart originally.
Maybe it’s a strange model that didn’t use them?? ???
They were missing. We ordered them and added them the next week. That engine is still running strong more than 1,000 hrs now
@@BusGreaseMonkey oops sorry about the double post. The first one disappeared. Now I see where it went. Always great to get a curveball thrown in at you when taking up the slack on a job.
Well done again.
Big thumbs up on this job.
You can put all 3 pistons in the bore of a Detroit, LOL!
I’m guessing he hydraulic locked the motor ?
Have you heard of the plierench? It's a really old design but it doesn't round bolts like a crescent wrench.
Don’t forget the valve rotator caps...
Nicely done. Darn metric stuff.....
Believe it or not , it’s alive. Nice job . The motor sounds pretty good and idels nice. I would be curious to know if the compression is with in spec considering you used the old pistons and shitty used rings. ( then again, who cares it’s running ) That motor is going in that big ass Cat ?
Docking motor's are traditionally fairly small for tight and controlled environments where you need a predictable throttle but I've seen a few used when its calm with fairly good results speed wise.
They are after all an Auxiliary engine.
tony66au I’m not much of a boat guy but I kinda figured that was its job. I was brought up to always go with “ big is better” theroy. Having said that, that little motor probably lived in that Cat and will go back “ home” a happily little camper. Go in peace little motor ✌️
New rings on all 3 cylinders but yes used pistons.
@@rickjohnson1632 Me neither but I was dragged along on a few boats as a teen and in my early 20's. These guys where very pernickity about using the right terms for the gear lol so I got an edumacation if I wanted it or not.
On the bright side the LOVED my old Bus when we would go camping or shooting and eventually a few Traded up although they kept the Captains hats so I dubbed them Couch (Coach) Captains and had a lot of fun with "Permission to come aboard" etc as most had more gold braid than a South American Dictator which is saying something lol
Thanks so much..
I have a 3 cyl. Perkins, very similar marinized Shibaura block..
Your excellent way of transferring knowledge is much appreciated.
Nicely done. Fun video. Foul language filter may be working too well :). But it ran.
That engine is still running strong 3 years later and many hundreds of hours usage
That's incredible.
You’re wearing gloves! What the hell?!!! Have you gone clean on us!!😃
Crescent wrench .....a.k.a. the Japanese fit-em-all
trucker 5167 That would be an Amurican fit em all.
Cheers
You're both wrong! It's a universal rounding-over tool.
Polish Toolbox!
Loose chain does not inspire confidence. GL
I believe you can repair /rebuild anything! So you have enough room in/on your bus to carry all the tools you need for such a verity of work or do you rent specialty tools for some jobs?
I usually have what i need on board my bus.
Miracle worker. That engine was in really bad shape. I think he should’ve at least replaced the rings and probably the pistons too while it was apart. But to each their own.
We did replace rings.
Oops, my mistake. Love your channel even though I’ve never owned a bus or anything diesel. I realize now that my comment seems way more “know it all” than I meant. Looking forward to the next video!
didnt sound like was hitting on all 3, speaking as a Yanmar owner. cool vid i cant believe what a mess that thing was and you got it to run:)
What brand battery rachet is that? I need one of those. Good job on Yanmar motor.
That's a new one. I don't think I've ever seen someone take straight up sand paper to a deck surface before.
Had you ever seen a submerged engine set for two years in a bilge of a boat with a head off open to the elements? A light cleaning to smooth out the rust ;)
@@BusGreaseMonkey I haven't though I think if the surface were bad enough to warrant sandpaper id probably take it to the be machined.
Honestly all my experience is with gasoline car engines. I've never even touched a marine diesel.
Love this Lil thing, Suck, Squish, Bang, Blow!
Im thinking the client was both Amazed and thrilled.
NO starting fluid on those small Yanmars! I have one of the old small tractors. On our forum we have seen more busted pitons and rings and cracked heads from that stuff!
this motor did pump water?
Hmmm, interesting. What will this engine go into / be put into?
I am amazed that there is not more blood on the job. There would be if I was doing it!
What's your impression of this engine, Scott? I've worked on a lot of older Yanmars and was impressed with quality of casting, machining, and fit. Almost as sweet as a 1960's Volvo as far as those criteria.
The fact that it’s alive again says a lot. I never touched a single 4 stroke diesel and this thing was simple to work on. Mechanical everything i loved it.
Great Job agian 👍👌
Wait, those only fire on every other revolution, don't they? How can you work on such a thing?
I know, very strange wasting a whole revolution for nothing...
Well done...
She lives, doesn't sound to bad either Yanmar and Kubotas must be good, the Chinese have been copying them for decades ;-)
That chain lying down the side of the front pulley could have got ugly real fast, but all good.
That’s why i had him shut it down cuz i saw that. Yikes
Can I ask, how did you become so knowledgeable in Diesel engines, transmissions, and buses and couches? You may have covered that question and if so I must have missed it sorry to say. Did you go to a trade school for diesel and then perhaps work for a large bus company garage. I enjoy watching your videos. I find them fascinating, Even though I don't own a bus, and most likely never will. But if I did, I know who I would want to work on it. Be careful out there, and keep enjoying your vocation.
I bought a bus, read the manual and started taking stuff apart. Then some friends needed help and after a few referrals it kind of took over my life..
@@BusGreaseMonkey I see very cool Self Taught, the best kind of education. I can kind of see that it took over your life. But it looks like you are enjoying it.
Is that a Harbour Freight torque wrench your using? I have a couple I use here around the house, but always wondered about their accuracy.
Was that SG there with you on that?
Cheers
Sounds good 👍
Ah, the universal metric-imperial fitall. Used properly has enabled any number of jobs to be competed. Used incorrectly it has wrecked many nut/bolt heads
what brand is your flex head flash light, is it rechargable LED?
It’s harbor freight. I have two of them one of the two quit charging after like two days. So i just switch batteries around to the one that charges. I like it but with one quitting like that so quick I’m not sure about recommending it. I’ve had them over a year and they both work great other than the one not charging. Strong magnet base, bright, three modes of light.
Part 1 ua-cam.com/video/MABdrvz2opA/v-deo.html
I can't believe you have the block laying on a battery????
Ya my metric adjustable comes in 5 sizes all the way from what the !! To wholly crap !! Lol . It’s almost to late to teach me the metric system, heck I’m 61 !
I am sorry that was ( Indian ). Thanks again
Shouldn't be spraying ether in those little Yanmars!! For whatever reason that stuff cracks the rings and blows holes in the piston. I can't tell you how many folks come to the Year forums with cracked rings from just one time useing it. Or they come with issues and we trace it back to useing ether to start them.
Wd40 was used.
Hate it when the customer is over my shoulder all day!
Where would you even find parts for this?
I let the customers work with me and at a discounted rate.
It's about 350 dollars for a complete overhaul kit. Pistons, sleeves, valves, bearings, gaskets, all of it. Why reuse all the damaged \ used parts? I've watched a few of your videos and you seem pretty competent so i just don't understand. These parts are easy to get.
Did you think it would run again? I was not so confident and i saw it in person all seized up. So we just played with it. It was just a Hail Mary we did for fun. When that thing came out of the bilge it was a lost cause.
Competent enough to get it running without spending the $350.
This was for a friend of his, I'm sure a paying customer would be different. Of course why pay attention to get all the facts?
@@quackattak Your rudeness is not warranted. The facts were noted. This is going in a boat, reliability is a major factor. As I stated I have watched a few of his other videos and I am impressed with his skill and knowledge. But, putting that in a boat is just silly. I think his friend should reconsider using it. P.S. I try not to troll, I talk to people as if they were in front of me. You should to.
What was the application? Small John Deere tractor? RV Generator ? Marine use?

Part 1
South Main Auto mister-o says every tool has a hammer side. Hardy har har
Yep I am going to depend on that engine whilst taking passengers on a cruising Dolphin tour boat in the Bahamas.. NOT... and not to say that you did not get it running again. which you did. But will need some TLC to get it to run reliably and for any period of time.. How far to the Bahamas from where the cat is sitting? we will see if it makes it..
He is going to put some time on it. Regardless i turned his seized anchor of an engine into a running engine in two afternoons, and a couple hundred bucks in parts.
@@BusGreaseMonkey I sir would be honored to have you work on any of my stuff. I was a sailboat capt. (Yamars) and a big boat Capt. 16v92's and 671's, Man's, Cat's, Cummins etc. for many years.. Now have a 1978 Oldsmobile Toronado 403 V8 front wheel drive Motorhome .. I would love for you to pass by and or come visit.. I watch your stuff out of pure pleasure.. I grew up in the Bahamas and one sister born there.. 64.. Andros, Nassau, Bimini etc. and know it very well.. The other sister in St. croix USVI.. and I am the oldest.. I do know about boats and the Bahamas.. and the Bahamian government. seen many pipe dreams about chartering in the Bahamas go up in smoke.. Now if you have friends fly in from the states and "visit" you.. that is a different story.. however you want to get around that.. My concern is for an abused engine he plans to depend on.. My Hat is always off to you and wish I had your help and expertise back when I was running those Roger Penske 16V92 DDEC pair of engines in the 70' Sportfish... We might have got a lot more Marlin fishing done..
This is his 14th boat and he’s been legally chartering in the Bahamas for 35 years... i think he’s got it covered
There was nothing wrong with that connecting rod.
That was nothing more than a “gentleman’s curve” it’s totally fine.
A slight bend is nothing to be alarmed about and is actually built into the specs.
😂😂😂😂😂😂😂😂
👍👌❤🇨🇦
Wow
Don't get that assembly lube on ya! It's known to the State of California to cause buck teeth in laboratory animals!
Did you think that was going to run?
@@BusGreaseMonkey I knew it'd run - been there many times, and have faith in your perseverance and skills, too. Only thing I worried about was the little fuel pumps - they can be finicky and refuse to pump - had luck riding shotgun with ya there!
so thats what happened to you?
Shit replace it with a 471t!! Lol
I bought that same shit circle plier.
Are you doing the cheapest rebuild as possible I mean only gasket so far that you mentioned is the head gasket you didn't get an oil pan gasket doesn't even look like you pulled the crank and change the front or rear main SEALS or anyting tell me if I'm wrong but
They don’t make an oil pan gasket, it’s like that from the factory. And yes he wanted to even see if it could be running again.
Sorry dude obviously the piece of crap was stronger than your snap ring pliers sorry
