My tool box is a mix and match of tool names. Lots of snap on and lots of craftsman. Some mack, gear wrench, proto,.... It depended on which I could get quicker when I needed it. Haven't used them professionally for some time but still rebuild old junk and maintain my fleet. And then there's the grandchildren!:) One nephew and one grandson working the trade. My time was in brakes, suspension, alignment and back in the day carbs and tune up. Always fun to watch a true professional at work. Thanks!

I work at the caterpillar engine facility where those engines are built it’s just crazy to see the engines from being built to running in a piece of equipment. BTW that specific engine started being built on 9/16/2018 and was completed on 9/24/2018.

I haven’t been watching this channel for very long. I’m a retired airline mechanic and my back just aches watching you work on this beast! You really earn your money!

Those huge dampers were interesting, had to be a weird vibration in that haul truck application. I used to build and test the big case ih floater trucks and on the rear cab mount pedestals were weights mounted on them. Just a bolt running through the pedestal with a bellville washer and about an 8ish pound round chunk of metal tightened to it. It sounds crude but without those installed the cab would vibrate when running. I always wondered who figured that out, kinda ingenious.

Any diesel content you present is very informative and easy to understand

Yeah, Im liking the equipment repairs! I have a tip for removing gaskets that are cooked on. It works best with very hard brittle gaskets. Take the ball end of a small ball peen hammer and tap on it. If its very brittle it will come off very easily in big chunks. If its still a little pliable it won’t shatter off nicely, but it still distorts the gasket enough to make it way easier to scrape off !

early 1980's 362 Peterbilt cabovers had 3 wiper arms

I use UV dye a couple three times a week to find leaks and a couple things I have learned is when adding to an engine, transmission, hydraulic systems is to pour the dye into oil/fluid and stir it to combine and the add that to engine/transmission/hydraulic system. The second is unless the leak is pouring out most Leaks require the vehicle/equipment/etc to be run/used instead of idling. The injector o-ring look like they have been exposed to something like brake fluid or something similar

Nice to see a mechanic who doesn't rely on "good enough."

Had a good laugh watching this. Gotta love it when the fittings spin and gotta grab that backup wrench

Nice hair cut, Jake Brake????????? Got chewed out by Cat, they are called Cat Compression Brake. The bolt-nut goes back to the 92U days. When the 5EK's came out, they did not have a oil relief slot on the stub shafts. Oil psi would build up and work around the threads. Oil would then leak out the front plate to block joint. I always replace the gear bushings while it is apart, along with all the self locking bolts in the gear train, cheap insurance. Have seen very few injector cup seals like what you have. Quality control at Cat must be slacking. Remind your followers what happens when you over torque the cam gear.

We still have one or two lmtvs with 3 wipers still kicking around. Pretty neat machines

That oil dye is very helpful. Great video, thank you.

Great video. I use a set of very sharp wood chisels for scraping. I’m with you. Less mess.

Did a transmission for a guy once. When I tried to blow the cooler out it was plugged tight. Afterwards I get the whole story. Previous owner hit a deer. Paid a guy 50 bucks to put a radiator in it. He left the dust cap on the cooler line and slid the hose over it and clamped it down. Van was never right after. Its why I always try to find the cause and always blow coolers out. Ya never knwo who did what before ya.

Before checking for an oil leak, I pressure wash all the old oil mess off so I have a clean slate to start off with. !

Thanx for all the extras in the videos. And for taking the time to explain why you do what you do. Also thanx for not killing the spider. It eats other bugs.

You my friend have a lot of patience which on a job like you do is a good thing ! Great video thanks for taking time make the video and narrating it for those of us who don't work on heavy equipment ! Your a true professional which makes it enjoyable to watch you work !

Brings back memories. Yes front structure and head. Also seen the cam shaft plate leak too. Had a C15 that the cam plate leaked all the time. Turned out the hole in the FS plate was out of round.
