Paying the stupid tax now so you don't have to pay it with interest later is probably my favorite line from this whole video.
Charlie is looking like she's loving the springtime grass! 🥰
Agree !!
One thing is for certain with Matt's episodes.
They're definitely worth the wait for one to post.
His patience and complete dedication to getting everything exactly right and his willingness to admit hos mistakes is a big reason I watch his channel diligently.
Thanks for the entertainment Matt.
First video I watched of his. Other channels definitely wouldn't say they forgot the injectors seals, ..twice 😆
Matt, you went way, way, way, above and beyond on that engine but boy it paid off. Fantastic job.
These days you're not even guaranteed that the $900 part you buy from the OEM isn't a re-boxed cheap Chinese part you can buy directly.
That's a shame. I'm not saying that the chicom version of something is garbage every time but if you're paying Mitsubishi or Toshiba or CAT prices, you should get the OEM part (bold stance, I know haha)
Agree
You should get what you pay for
Or a used part someone returned as new
Allow me to make a comment here. I am a retired truck fleet maintenance manager. Back in the early 90s, my lead mechanic came into my office and asked me to come look at something on a Ford LN9000 he was replacing axle bearings on. We used OEM parts exclusively in our fleet of mostly Kenworth and this one lone Ford. He had an axle bearing still in the box on the frame. He picked it up and showed me on the label Made in China. Mind you, this was in the early 1990s and this was a Ford part bought from the local Ford dealer marked Genuine Ford but made in China. So, that said, OEM from the dealer doesn't necessarily mean it wasn't made in China.
"After the oil cooler I guess the rest will be smooth sailing" - a few seconds later the intake manifold cracks. An important lesson to us all this one, the garage gods are always watching and love a good jinx :) Great video as always, and amazed what you are able to do with limited resources.
Murphy, is always watching !
And he don't obey restraining orders .
Cast aluminum can be a royal pain but it can be welded. The guy who welded that piece did a nice job. I welded aluminum for 27 years until I retired. Keep Smilin Matt, things are lookin good. 👍
I've known a few folks who were absolute wizards with aluminum .
All sadly long gone now .
@@kaboom4679 sadly your right
Being able to weld and repair cast aluminum separates the masters from the good.
Age old saying”I did it right because I did it twice”
You were very restrained, love to see the out takes.
I just want to say I’m a big fan of you and your channel and I’m learning a lot from your patience and doing things precisely
I’ve never been so invested in a machine I’ll never see!
You should see the Catapiller build !
Once again, I appreciate your attention to detail, your willingness to go back and correct issues, and following your hunches on possible problems. Looking forward to seeing and hearing the engine start up and running, wish you the best. Thanks for the update, appreciate your time and effort.
I could not agree more with your comment!! Matt’s attention to detail AND his calm acceptance when an error is detected to simply make the correction without self criticism impresses me hugely! I am reminded of one of my graduate instructors maxims
“CHOOSE THE HARDER RIGHT VERSUS
THE EASIER WRONG!” It saved me & my patients hours of unnecessary corrections! I salute Matt every time I watch his videos!!
Matt, it's a breath of fresh air for you to research, read manuals, study online materials and document the work you are doing. You also err on the side of doing more to be right. I have watched many people on different UA-cam channels just wing it and hope for the best. My concerns have always been that if someone is watching videos to attempt to learn how to do something they are being horribly misguided by these people. Thanks for setting a good example and with your ethics things may be harder and cost more sometimes but in the end you will be rewarded and most of all, be at peace with yourself. Good luck.
*- Matt, this is the first time I have watched any video twice.*
*- My lady says she likes your energy doing this, and she can't even use scissors.*
*- She says you are "competent and friendly and give people a good feeling and a good leader because of that".*
*- I think she picks up on your sense of humor about struggling with things.*
*- It is hidden and quiet, and inviting.*
thank you
All good Matt. Most of us have paid the stupid tax a time or two. Great video!
your doing a fine job matt, now you have a dozer , excavator, tractor , now set your mind on a dump truck and quit worry about small things, all mishaps are lessons learned matt , we all went through it as you are now
make 3 marks , 2 on rod and one on the socket when you angle torque , i learned this lesson between the saddle tanks on semi trucks and torqueing with a 6 ft chetta pipe someone torques and someone holds the socket
This video gives me hope that a schlub like me could maybe, possibly, with enough caffeine, do this. Videos are excellent. Focus is sharp, lighting is excellent. Never a problem with audio. Superb shot of Charlie! So beautiful.
The long awaited posting is up. 💪
That damaged thread treatment was brilliant!
One of the fun things about watching you is your ability to have to do everything twice. I can certainly relate. I never do anything right the first time. Lol. But on the bright side, you do learn from your mistakes.
I was wondering where Charlie was. and thx for showing how you calibrate a torque wrench. That was interesting.
I’m late 70’s and enjoyed every moment of your rebuilds. Came to realize that all those years ago I was wise to not go into engine assembly.
PNWH finishing the engine, and Squatch does a steel radiator cowl.. busy youtube day👏🏻👏🏻👏🏻👌
Over the years I have learned to listen to that "6th" sense. You are wise to follow you gut feel. Yes, it costs a bit of time and money, but it turns out for the best in the end.
Great job Matt! Love your attention to detail. Thanks for showing Charle. She's a beautiful dog. In your previous vids when you're on the ground working on something and she walks into frame and drops her ball in front of you; love that. So cute. Keep up the awesome work, man! 🙂
Nice to see someone calibrating a torque wrench. Have checked the weights to see if they really weigh as labeled? Mine do not.
Exactly what I came here to comment. Those weights can easily add up to be off by that 10% you discovered to be missing. Will the scale you use to check those weights be very accurate at 50lbs? Also doubtful, but definitely better than what's stamped on the dumbell :P For mission-critical torqueing I'd say the cheapest and most accurate way to achieve it would be to send in the wrench to be calibrated.
I couldn't agree more. You need to use the proper equipment to calibrate a torque wrench. Arm curl weights and fish scales don't cut it. He should compare his wrench to a high end one and see if there are significant differences. His local machine and engine shops will have them. As it is, I wouldn't trust his "calibrated" wrench at all. @@rokask
Great to see you are back. Thanks for your honesty and for being a top quality presenter.
Very cool way to calibrate the torque wrenches. Great Video.
I commend your patience and understanding that things don’t always go smoothly the first time around. You are doing a great job, having skin in the game, and knowledge of things mechanical. Looking forward to hearing it as the assembly lubricant burns off and the steady purr of your fresh powerplant 😊. Going to be a digging beast! 😮 😂 😊👍👍
I am surprised you don't have additional subscribers. Very impressed with your engineering talents
Matt,your patience is admirable,that motor looks just great,you have turned a piece coal into a diamond,looks to me that Charlie is keeping an eye on you,thanks for the video and all the best from Perth 🇦🇺👌👌👌👌👌👌
You have the feel down! You have been at it so long that you are well in tune with your tools and work pieces
That engine looks like a work of art, Matt. Beautiful work.
I'm sure you've heard the saying, Matt..."We do it nice, because we do it twice!". Generally spoken by everyone who has ever made a mistake and had to go back and start over. You're in good company.
Great content as usual…. Do not worry about mistakes, massive project and lots to remember……….Keep them coming…..UK
I was mad that UA-cam wasn't showing me your videos, But you wasn't making it fast enough 😅, injoyed it as always, Later Matt.
Charley is a handsome devil, thanks for sharing him with us.
Well done Matt, not long to go. I think one other challenge is the mess of all the hydraulic lines and hoses. I really enjoyed the end part of the video. I had no idea you could adjust torque wrenches at home with very simple setups.
Don't forget to oil the turbo before starting the engine. It takes a while for the oil to reach the turbo and you can ruin it pretty quickly if it's dry.
As for reusing bolts, typically (not a rule) the ones that are meant to be tightened at an angle are not reusable.
About the water pump pulley, I have a similar engine in my truck and the pump has a spacer on the inside, in my case the pulley does not touch the water pump but without the spacer the belt does not align well , keep that in mind.
And that alternator pulley is shot, you better get a new one or you'll have noises everywhere.
Torque to yield rocker arm assembly...who knew?
So very awesome!!! Loving the engine rebuild series! Can't wait to see the excavator up and running!
Keep em coming!!!!
Nice job, warts and all! I especially like how, when things go wrong, you just shrug and say, "no problem, I can fix it." No angry antics, just accept and move on. Good for a long life! Our female pup was named "Charlie", too! ♥
As close you can get an Old used and abused machine to new again, thats whats this show is About 🤩🤩 it´s an amasing work you put down to this🙌
I seem to remember being taught 50 years ago in machine design, to always torque bolts with dry threads, as friction is involved with holding that fastener tight. I had to look that up, tho.
"Always assume the torque is a dry value unless a lubricant is specified. If any lubricant gets on the fastener and no lubricant is mentioned or specified, then using the torque value laid down could over tighten the joint or the fastener itself." Every engineer has a different book.
Lordy help us. Keep'm coming, Matt. Love your content and dry humor.
Lots of problems but lots of good recoveries. Well done. Thanks for the shoutout.
It was like watching the big game , there were cheers , there were tears as when the manifold cracked , edge of the seat moments like waiting for that final torque click on said manifold , and laughs at the potemkin damper pulley , painted gold like the proverbial polished turd.
Sorry for the pitfalls along the way , but the home strait for the engine is in sight , another milestone soon to be in your rear-view mirror.
You impress me every video cast. You truly a master mechanic.👍✌️👌🤞
That engine is positively glowing. Beautiful work!
I like how you just pointed at dropping the paint marker after you dropped it do that often
I love this channel
Your mentality/approach to overcoming adversity is incredibly refreshing and motivating
I genuinely find myself taking pause to calm down and employ your levelheadedness when things start going sideways on me out in the shop haha
Anyway, love the videos and I hope you keep em coming!
Always grind,or cut way far away from engine assembly area. Beautiful dog I miss mine.
Stay safe and we'll see you next time.
Matt, thanks for taking us along. Great job!
As always another amazing video - your problem solving skills are amazing as is your attention to detail. - I mentioned your channel to Matt over at the Diesel Creek channel who just got a small excavator like yours and is planning to do a rebuild - mentioned how great your rebuilds are.
you do it NICE because you do it TWICE it only makes you sure. Never hurt anything to recheck.
Great video thanks for sharing. Don't worry about sharing a step that might be redundant making the video a little longer we can always fast forward if we're not interested. Thanks again.
Great Job so far Matt, you took 2 steps foreward, and 1 step backwards, butt u are getting there. lv to Charlie..
JUST KNOW ... Along with the trusted use of an ISUZU Engine for this application, they are used throughout the world for many applications. In fact, and most people don't know this, the DURAMAX Engine in my GM one ton dually is an ISUZU Engine. They have been reliably used in GM trucks for over a decade along with continuation models that just keep getting better. The aftermarket and builders are now producing over 2,000 HP along with built Allison Transmissions that can take the power.
Well if nothing else, it looks damn good!!!!😊
Looking forward to seeing this engine running.
I would suggeat that your fix on the oil cooler is actually better/stronger than the original, and a lot more suitable a way of attaching that the original option.
The replacement one came with studs, so apparently someone else figured it out too lol
You deserve way more subscribers. Great video, of course.
Matt, there is an angle gauge that you can use for torque plus angle bolts. They are extremely handy when you’re dealing with 12 point. Harbor Freight has some and so does Snap-On. Hope this helps.
Last chapter is the best chapter 🙂
When punching holes in gaskets sometimes it is best to punch bolt holes before cutting gasket out to prevent tearing or breaking out.
Great video Matt, you are a true professional and show us all your mistakes which are very few and you seem to have a bit of luck on your side in catching them. I pay more in stupid taxes than you do it seems.
Dog is a star!
Love your videos and your style of naration.
Thanks for letting us into your workshop!
Best fixup videos out there, but the time between videos are killing your numbers easy 100000 channel.
A thing of beauty! Awesome.When I saw the completed engine (on you lead-in part of the video), I lost my breath. WOW!!!
You have amazing patience ! I can’t imagine doing all that
Another excellent video Sir! Your perseverance and patience are serving you well. Well done on getting your manifold welded up, and I reckon that is a good call in replacing the oil cooler. They may only be 4 little bitty fixings that you modified, but if one were to fail, then that is a whole new game of stripping, cleaning, replacing and rebuilding parts of an engine that would probably be buried back in the engine bay of a machine stranded out in the sticks! 😪
I think you're done a really super job trying to repair that cooler. It probably never would have been a problem but not the second guess yourself I guess it's not a bad thing to put a new one on. Doing a wonderful job being a little bit over-cautious but that's fine for your first motor. All the best from Surrey BC Canada
Man I am enjoying this series! Amazing attention to detail.
This is weird man, i just had a feeling you had a new upload. No notification, no analyzing your upload schedule, I just had a feeling that your content was want i wanted in this particular point in time, and BOOM, there you are with a day old video! 😁
Great Vid Matt, and Charlie is one beautiful Shepard!
Nice job repairing the cooler. I do understand your concern and decision to replace it. I'm looking forward to the next video. Thanks for including some footage of Charlie... I was missing her sleeping in the background as you worked.
Thanks for sharing.
Keep pecking away at it Matt, you will be slinging mud with that excavator in no time.
I put a used 4 cyl Datsun diesel engine in my 1978 Datsun truck and checked the installed glow plugs with an ohm meter. Two of the glow plugs seemed pretty good and two were dead. I pulled them out and connected a +/- jumper pair to 12 V.DC The glow plugs that seemed pretty good had only 1 of the 4 elements working. So my rule is pull them out and power them up. They should glow white hot. The engine smoked teribly when first cranked with the old plugs installed. No smoke when cranked using the new glow plugs. I was surprised that the glow plug elements had segments to provide heat.

I'm impressed that you found that bad harmonic balancer. I fixed cars for 20 years, (ASE Master Tech) and I honestly don't think I would have. Well done.
Can't wait to hear it run Matt,great job!
You can use coffee filters for low cost lint free towels.
It's not surprising there's few people that will tackle cast aluminium, depending on the quality of the casting material, it can look good on the surface but once you apply heat it can fall apart as the inner structure can resemble Swiss cheese! And once it does that there's no going back.
Kudos to whomever did the repair, they did a nice job!
Another awesome job sir. I wait for your great videos.
To quote Rainman Ray "I love my job so much I do it twice"
Wow Matt, looks brandy new!👍
I was thinking the same thing
A trick my dad taught me about stripped female threads about 60 yrs ago. Heat the bolt with a propane torch until solder flows into the threads and fill them about half way. The solder is soft enough to conform to what’s left of the threads and will torque right down. But your solution was great, I would not have thought of that.
put Vaseline on the copper washers when inserting them into the head so they dont fall off
Just in time for my lunch break!
What the..!!!! New bolts , Gaskets, calibrating tools...Amazing!😀👌
Great stuff! Worth taking the time to get everything right given how much effort you've put into this!!
Your video quality is pretty good as of late. I dont know if new camera/lighting / editing, doesnt matter, very good indeed
Down in central Florida there's a heavy equipment scrapyard the guys been collecting machines for years. I could get the name for you from a fellow youtuber who hauls stuff to the guy. But I bet I saw at least 30 of those size machines. Acres and acres ..good work
Nice job, I'd let you build my engines anytime with the attention to detail you have! Pretty sad with the balancer, I wonder how many engines are out there about to self destruct because of products like that..sad...Anyways always look forward to your videos.
Hi Matt,
Enjoying your rebuild mission. I just want let you know when I replaced turbo's I tried to replace the mounting nuts with brass nuts. They don't rust up break off the stud. Yes they strip but its just learning not to over tight them. It took me a couple times to learn that I was not bolting the wheels. It made life much easier for the future you,
that is a good idea, I might try that
A couple of things I like to do when torquing head bolts is before I remove the socket from the bolt I'm torquing, I look at the next one in sequence. Also, as I'm running them down by hand, I do that in sequence. I do this because it starts my muscle memory on the sequence.
As long as you get them all done correctly, that's the important part, but that's just a couple of things I do to compensate for a bad memory.
That engine is looking awesome!
I cracked up when you said 7th sense haha paranoia running strong in the video, love it keep it up so fun to watch!
I had an Air Force Training Instructor that drilled into every training person that ALL extensions flex, and need to be checked to find out how much torque is lost by flex of extension. I think he was right at the time but I also think the metal used now is much better. But just yesterday I broke a 1/2 inch extension(4 inch) from Harbor Freight torquing down lug nuts. As they say Buyer BEWARE. Have A Great Day.
For making large holes (2-3 inches) I use circular leather ring cutters. You can do the ID as well as the OD for a thin gasket, too. Just set one on the work, place a piece of wood on top of the cutter and wack it with your favorite hammer. I use them for making cork gaskets used on sediment bowls on gas tractors, or anything else that needs a nice round hole. I used to whittle the holes before trying those cutting rings.
That dangler is an interesting addition to those sure shot style brake clean cans. I might have to try one.
Great video again I'm not a engineer but love to watching engineers videos and machine repair , also thanks for showing Charlie always good to see the Boss
nice to see charlie can not wait to hear it run
Thanks for the video, Matt!! It's never easy to do these rebuilds in your 'garage', but hang in there!! Good progress this week!😀
