Area diesel service saving UA-camrs bacon all over the internet. Love to see you taking the time to clean and paint. It’s going to be a great rebuild.
Hear, hear!
ADS✔️✔️
The people that did rebuild your pump did you right. That was a good deal.
It seem like Area Diesel has a lot better grasp of fuel injection most places that are around . Bless them.
Area diesel does more than just pumps. They go out of their way to find parts no one else can find for other parts of engines and transmissions. Remarkable work your doing
If they can't get a part they make or modify to run factory fresh
Area Diesel Service have done the best marketing a business can do as far as I’m concerned. Helping all the major UA-camrs while recording their repairs and giving video tours. Even see some of the guys rocking their merch years later.
I’ll think of them first if I ever need a pump rebuilt.
I had watched the injector pump rebuild and it was a very professional presentation!
YT recommended the Area Diesel injection pump rebuild before this latest video was up. It’s well worth the watch. Now I know two things: 1/ Area Diesel does high quality work 2/ don’t bother with a diesel injection pump rebuild at home. There a ton of specialized knowledge and tooling, and obviously way more complicated than a hydraulic pump or gas fuel pump rebuild (so don’t fool yourself into thinking this will be like “other pumps” you’ve rebuilt).
Area diesel for the huge win! I love seeing honest and hard working shops still out there instead of trying to go the easy route and rip people off
Another great video of Matt attempting to muddle his way through things he's never done before!
Perfect! Let's get this thing digging!
Man...Area Diesel really does UA-camrs right, i am sure regular customers as well. I will be using them just how they treat people
Matt has two of the best lines in all YT...
"That's not good...."
"Take two..."
You forgot "That's heavy.."
You forgot "Oh Oh"
"There we go"
And Future Matt
Area diesel did a great job for you. I've watched their vids with other youtubers, (jims machine & dirtperfect) and they go above and beyond.
Shout out to the Uncle Tony reference. That dude is an absolute GOAT of the performance car realm. Side note, thanks again for all the effort you put into these videos, oddly satisfying to watch your struggles with this old junk.
I've watched many ADS vids they've done in collaboration with other channels. I really respect how deeply skilled they are at their craft, and I'm glad you got connected to them, Matt, as that kind of quality service is hard to find.
Your way of building that motor is mint . Mistakes are made when rushed and your make n sure the all is in spec !!! Cant wait to see you put it all back together!! An work with it
ADS video for your pump was the best that I've watched, very good quality.
Area Diesel lads are serious pros for sure. First saw them tear apart a lift pump for Watch Wes Work and this old timer of a forklift that may have been from the Korean war era or something... Wes has a serious bit of engineering knowledge stacked up to his credit and he was like "Holy Cow guys... Wow!" lol Worth going back and looking over those forklift vids again soon for me [they were what hooked me on Wes's paage after all a few years ago].
I like how u stick to a project, work through it. And ur actually reading a manufacturer specs. I love that attention to detail. Thanks for the great content. Can’t wait for next one, will be waiting
Default colour for Isuzu is a mid grey for those who are triggered by those things.
Also a trick for brushing out holes. If you find the brush is too tight DON'T just pull it out twist it before you pull.
As for the time taken to do the job. It is always "Take as long as you need to do the job properly and not one second longer"
This is by far my favorite channel on YT! Having a hard time waiting for the next one, but it´s definately worth the wait!!! (yep, 3 exclamation marks there) 😊
Wow...that pump. Hell of a job they did. Great video of it as well. That thing is beautiful Matt. They certainly did you right
Thanks for the update
You are inspiring
As far as i’m concerned Matt, don’t worry about trying to entertain us, your videos are just what I want to watch and follow. I also like your modesty and that you don’t edit out the mistakes. An added bonus is, my German Shepherd is a body and behaviour double of yours. 🇬🇧
I always enjoy it when a new video of yours shows up on my subscription feed!
Always look forward to your videos! I do watch ADS’s video of the there rebuild a couple weeks ago. Those guys know there stuff! I’ve seen them rebuild a couple 2 or 3 from other changes I watch. Seems like you can’t go wrong sending them your stuff.
I'm not sure why it always seems that fuel injection shops always return components all disassembled when customers refuse to pay for their outrageous quotes..as if to say "figure out your self".. area diesel is the way to go.
28:53 I agree it is NOT critical! :) ... BUT custom fitting the piston rings like that (I always do) Is something YOU can do that shop will not probably waste time on ... :)
Just imagine when your in your 70's and go to use the excavator .. and have confidence the engine will be fine for another year ... as and you did everything the best way!! :)
Matt. I see this time and again. REAL Americans like you are wise and can adapt to the situation you are in. I have really enjoyed the Hitachi videos (just subscribed so I am binge watching) Very smart purchase, older tech, far fewer wires, no emissions garbage. Taking out the engine was easily the smartest thing you did. I predict this machine will be a real workhorse for you and you may have it for decades. Brilliant channel. 👌
Area diesel service, saw the video and gave them kudos.t. Love to see you taking the time to clean and paint. It’s going to be a great rebuild. 51:27 you've just teed off a bunch of Chrysler freaks. Oh well, Se la vie.
Matt,with all the TLC you’ve given this build it’s going to be better than new, FYI on this side of the world no rain for 3 months temperature above 38 Celsius days 24 nights thanks for the video ,all the best from Perth🇦🇺
I did the torch method on our cast hydraulic governor cases before painting and it made a huge difference in the adhesion of the paint. Amazing how much moisture is in the pores of the metal.
Metal has moisture in it and before welding thick metal I always heated it with a big propane torch.
Ya, I wish I'd known that trick last year when I painted my block!!!!
ADS seems to be the go to for anything diesel!
I’ll watch this silliness all day thanks Matt, good to see Charlie has lost the lamp shade, and man it looks cold there ❄️
Hi Matt, thanks for this engine rebuild update. Remarkable video with narration and explanation of each step along the way. Your meticulous adherence to “spec” tolerances and attention to detail is admirable. Looking forward to completion and the “test-run” on the engine stand. Keep up the great work!
Matt your attention to cleanliness and detail is awesome and the fact that if you are in doubt you don’t hesitate to replace with new parts will be a real winner in the long run. I know you profess to be a hillbilly mechanic but I love your methodical process and oratory as you go, all makes for an awesome viewing experience for us. Big shout out to Area Diesel Services for another great job
Definitely should've had Area Diesel handle the pump from the start, they are true professionals.
You deserve a large shop with all the tooling you need, you do great work and detailed in all the right spots.
Have heard nothing but good things about Area Diesel Service...proper professionals who treat people right..👍
A lot of the things you do, Matt, may seem unnecessary to some, but no one can fault your attention to detail...a lot easier to make sure things are correct now while the engine is out of the machine and you can easily access it...some things can be a proper ball ache in a cramped engine bay.
Already looking forward to the next installment....keep up the good work, buddy...😊👍
Just to let you know this is really a privilege to watch you do the engine rebuild and all the other components that you've done rebuilds and servicing to it has been a really cool time to watch and learn as you of course have learned to make this stuff happen!! All the best from Surrey BC Canada
Keep working on the Excavator rebuild your doing a great job and really enjoy watching you work on it.
What a treat to end a mediocre day with a cool video from Matt.
Quit being so hard on yourself! You are doing a fantastic job, the cleaning outside was pretty much the proof that you have gone over the edge 😂. Appreciate the warped sense of humor, the little cracks made me snicker on a couple of occasions. You are doing what everyone Should, but some cut corners, and we all know how that comes back and bites you in the sit down! As far as leaks go…. Ain’t going to happen. Positive thoughts here, patience and double checking does wonders for the outcome. I remember clearly the first test hop in the first helicopter that I completely overhauled totally by myself (1984) and it was so good on the first start up West Chazy hopped out of the compound and were immediately running 70 knots across the field at three feet above the ground followed by the required vertical up to kill the airspeed, to the 180 back to the ground, leveling off at three feet and 70 knots. You can’t forget something that awesome. Back to a climb to 1200 feet, then chop the throttle to idle into an outorotation. Top of the green arc at 60 knots at idle. Perfect! Concentration, following proven practices, double checking EVERYTHING makes all the difference. You have this, it’s going to be just fine 😊. ( analytical response.) 😮😂😊😊😊😊😊😊😊
Let’s have a round of applause for Matt’s shop press. That thing got a workout on the cat dozer. It’s still toddling along!!!
Thank you for doing this. Most people I know are like you, amateurs. It is very helpful for us to watch you do your work. Thank you.
An amazing amount of important DETAILS revealed in this video. I have much more admiration now for folks who work on big machines. I learned a lot. Thanks again for your wonderful content. I'm a surgeon who can operate w tiny instruments two mm's from brain tissue....but I can't drive a nail straight. Even with a .........nail gun!! LOL
Matt, I love this series, I'm learning a lot. Between you and C&C Equipment and the other UA-camrs, I'll be a pro in no time. Great work! You can film whatever you want I will watch it.
Looks great Matt . I did like the color of the primer on the block,instead of black..
Nah I'm not screaming at the screen I'm enjoying the whole process and waiting patiently. Love your videos!!
Fun facts about piston and bore sizing.
On the block headface you can see some letters stamped. These are the original bore size and the pistons were selected to fit this size. A is the smallest size B is nominal and C is the largest in the standard size range. Some makers will go to D and E if they are having trouble holding tolerance for some reason.
When the rings are fitted they are all the same size regardless of bore size.
Some makers will also grade the wrist pin size in the piston to allow for machining tolerances too.
The plugs in the oil galleries are often a tapered thread and a loctite coating is applied at fitment.
When checking the crank runout you should fit the caps and snug them down because the bore is not truly round until the caps are torqued.
Cheers Eric
Man, I bet area diesels business is uh boomin. There are several UA-camrs that use them. Great video man, can wait to see this thing all put back together.
It’s amazing how functionally new a rebuilt diesel engine can become. Great stuff Matt!
I had an engine that sat with water in it and rusted out the iron liners. Honed it and put new pistons and rings and it runs like new.
ADS did an outstanding job! Great video on their channel. You do a lot of work, and don't back down from much. Glad that you used them
That injector pump looks like new! Those blokes do awesome work. This motors gonna run like a clock! Great work Matt! 🇦🇺🍺🍺
Man your attention to detail is superior. This thing will be better than new.
quality repair by real people total craftsman mechanic ! i worked in car restorations - and quality is hard to find ! great Matt thanks !
I'm a Southern Appalachian hillbilly & I like your vids very much 😊 😂
Area Diesel has been awesome. You made a wise choice dealing with them. I'm really enjoying your videos.
Don’t worry about it dude… your doing a great job.
Man I just love your videos I love your attention to detail your work is awesome take care can't wait to see the next video
Been watching since the start of the d4u. I like heavy equipment and building engines and diesels. I want to buy a piece of equipment but you have me thinking finding a worn out ish one and rebuilding it. Thanks for taking the time to do this and posting it. I changed my name to what it is because my son called me that after seeing your channel name. Thought it would be funny. Almost had him convinced its always been that.
You are do'in just fine young man. I would not have had the patience to video my MG rebuild, that one took 4 years of working on it every day after work.
No screaming from me. I enjoy your demeanor and approach to building. Keep on keeping on. It appears that once you accomplish your task, a quality product comes from it.
ADS is the absolute best in the rebuild industry. Glad you discovered them!
Your efforts and dedication to doing the job correctly are extremely satisfying. Can’t wait for the next steps in the engine rebuild and really look forward to seeing your machine work. Great job!!!😊😊👍
Your attention to detail is commendable, most people would have just accepted that it had been cleaned at the shop and called it a day, well spotted🇬🇧😃
Matt..man, it’s another great video. This entire excavator series has been quite interesting to watch..👍🏻
It appears you know pretty much what your doing it should be a great build.
You are far more talented than you give your self credit for. Amazing patients and skill. Your videos are very entertaining. Thanks for sharing.
LOL ! Mopar or no car ! Good progress ! With along way to go ! Thanks for sharing !
Important! When installing the piston rings onto the new pistons, use a quality piston ring spreading tool. Do NOT try to wind them in (spiral install them). You will ruin the rings. I’ve enjoyed all your videos. Keep going strong. YAY for you!!! I also enjoyed Bay Area Diesel video rebuilding your injection pump. Thanks for showing us all your hard work and ingenuity. Rob
It's NOT Bay Area. They are in Illinois.
Matt, hi from Australia. That nibbler looks cool but you need a plasma cutter man. Where I work has one, they're a hoot, making cutting shapes easy peasy. I love your videos, keep up the good work.
Wow the pump looks like a work of art.😲
Area Diesel is awesome about precision and preparing the job for a oem or better than oem apon completion. Every company around me uses them for all diesel inspections and turbo work. And you clearly know that cleaning the oil gallery is very critical if you don't want to repeat the process again. Plus sealing the cast iron parts not only stopping rusted but all metal is porase and will seap so painting it is also a sealer. Great job on your project, can't wait to see the next video.
Good job. I’ve enjoyed your work since the caterpillar.
I love watching Matt use parts cleaner right next to the open flames on the space heater! Adds an element of danger.
Checked out Area Diesel's build video , seeing the work they put into just calibrating and tuning , it's clearly one job requiring very specific expertise, which luckily they had in abundance.
So a big shout out to them for their build/rebuild/creation of a pristine pump .
Block is looking fantastic, so the injector pump will match nicely. And you're right, given the amount of work you've put in getting to this stage it'd be a shame to cut corners , it'd be like building a lamborghini from scratch , then doing the paint job with a whitewash brush.
You are doing a great job with this project I don’t think I would ever be able to finish a project like this thanks for sharing
Really good idea to run the engine on test stand. Ensure no leaks, run it up to temp and get all the adjustments done.
You were very very wise to clean those passages and galleries. Judging by the goo in there, you would have wiped a bearing in very short order. Way to go.
You’re doing an awesome job for someone that has very little experience! Keep up the work & keep those videos coming!!
You are doing a great job on the cleaning and checking the specs on parts and getting everything ready to be assembled, and makes sense to me to break the engine in out of the machine, easy to deal with any problem that might arise and not have to go thru taking it back out of the machine. I really appreciate your attention to detail, it is a pleasure to watch you go thru the engine. Thank you for the video.
Great video, super entertaining. Can’t wait for the next one!
Awesome area diesel service again saves the day man they go above and beyond looks brand spankers new pretty peeved of that shop didn't rebuild it but I suppose it was better for the ADS teardown
Thanks for another really interesting video, there’s no doubt in my mind you did the right thing getting Area Diesel Services to rebuild that pump
Brother keep doing what you're doing. You are learning and so am I. It's your engine, do things the way you see as best. Love watching your videos, been watching since the bulldozer build. Great to see these complete tear downs. Rather than just part of the machine getting fixed.❤
I had a chat with my armchair and we both agree you’re doing it right.
Love your content. Take your time and make it right
I learned something new from this video. Never thought about the brushes and cleaning port holes. I've done one engine rebuild. It was an inframe on a 78 ford f150 pickup. Did this at age 22 with my grandfather who had the tools and showed me how to do it. This process cured me of Ford products. I avoid their vehicles ever since.
Nice to see you mostly working inside and taking the time for some ‘relaxing’ painting😉
Area Diesel will get my business if I ever need them.
Thanks for the video, very interesting. You might consider having the crank Magnafluxed for check for cracks you can't see.
I can't speak for every one else. Personally I'm enjoying your content. You explain your reasons without using all the technical mumbo jumbo. Plus 99% of your video shows exactly what your seeing. That makes a huge difference. I'm also a fan of seeing the opps everyone makes but few share. The two on the oil pan testing were, opps's I would have made.
Over all wonderful videos!
My apologies for not getting to the video right away.
I have to make time for videos over 40mins but I do remember to come back and view.👍
Had someone I know screwed in cam bolt and forgot to tighten it when he assembled his engine. Had to rebuild his engine again. When I was diesel mechanic, I never put a bolt in without tightening it or tagging it. I worked on a lot of Isuzu engines. We were a dealer for GMC and Isuzu. I really like your attention to detail.
Your effort is showing Matt. Keep your standards up, it'll save you in the long run.
Hey man, we all love your long vids. Riveting stuff and keeps us entertained watching these increadable builds/repairs.
Regards from South Africa
Long oil galleries like you have there can be scrubbed out with shot gun cleaning rods and brushes. You can get the brushes in either bronze or stainless steel bristles. Most often the rods are long enough to go all the way through the block. You do very nice work with the tooling you have to work with.
11:40 "They've got some type of secret schmo" 😅 That just cracks me up, they way he says that. Pretty sure he's not impressed by the secrete schmo.
Saw the ADS video they did a bang up job
Highly recommend to take the extra bit of time and run a tap (unless it specifically says a "thread cutting" tap and the price is ten or more times the price of normal taps and dies it is a thread chasing die which are not labeled thus) on all threaded holes. You will be surprised how inaccessible they can be when you decide to add a component down the road for whatever reason. Actual thread cutting dies will many times have adjustments so that several passes can be made to cut the full thread rather than trying to hog it out at one pass.
Matt - I admire that you are a man of focus, commitment, and sheer will. It's nothing but fun and interesting to watch what you are up to. Keep up the great work and great videos, sir!
I’m thrilled to see another video of excavator rebuild! You do a great job of not only rebuilding but of explaining and videoing! Keep up the great work!
