I’ve been watching your videos for a few months and I have to say that the way you explain how systems work is very easy for me to understand. Your teaching me about truck repairs that I didn’t think I needed to know. You have inspired me to take on my own project truck a 2007 Kodiak that has many opportunities to put what I’m learning from you to work. I have started going through your whole video catalog just to see what else I can learn. Thank you for these videos I find them very informative
J.C. you are a good, easy to understand teacher. I really appreciate that. There are too many folks who were "taught" by people who don't understand what they are teaching. They are just repeating some unclear sentences!
Thank you for showing the fundamentals on how these systems work. A lot of intricacy, and you explain it in detail. Thank you for sharing. Have a good day
That seal come out like it wasn't supposed to be in there. I have changed a thousand of them and never had 1 come out as easy as that looked. Well, maybe not a thousand, but more than I cared to swear at! Great tutorial on how air brakes work. A lot of general viewers and some truck drivers don't have a clue to the mechanical end of how a truck works.
Very informative video J.C 🙂👍 It's getting closer to being done! I liked the driveshaft u-joint explanation. I hope you and the misses are having a great week 🔧
Great explanation on the basics of air brakes. That pinion seal was thrashed, but at least it came out easily. The Tiger Tool puller set is a pretty neat piece of kit.👍
That’s a good explanation of all of the stuff that goes into those systems. You know I’m gonna watch 5 times before I understand it. I have to straighten out the air dryer and the lines that come out by the pintle hook 🪝 for the dolly for the doubles
JC, as you know i don't work on heavy kit like you do but thanks to you i know how a few things work and it does make the videos more interesting as i can keep up. Great work, appreciate it.
I've got a seal puller just like that, it's hit or miss, sometimes it pulls the seal, sometimes it just pokes through and tears the seal apart. Better than a long screwdriver though! Another excellent description of that modulating valve. Thanks for the video! Stay warm!
Thanks for taking the time to explain air braking systems as well as how proper drive line angle and alignment is crucial to minimize vibration, wear and tear.
Great video as always, I've learned tons from your videos that have helped with my build(s). I've got a 2009 F550 that I've stretched 4 feet to fit a 16 foot deck, doing a 4wd swap, moving the rear axle back the length of the transfer case and swapping the rear to air ride too. Thanks for going into such detail with everything!
My best gotcha driveline story is from back in the days of jacking up 4×4 pickups and slapping huge mud tires on stock drivetrains. An acquaintance of mine had a shortbed GMC that had some crazy pinion and transmission joint angles. While out off roading the rear axle ceased to pull. Looking at the underside the driveshaft just spun and oil was seeping out the pinion. No nasty noises were coming from the axle so we locked the front hubs and limped home. Fully expecting to have to change the rear axle I was pulling the bolts out of the U-joint when the driveshaft spun around. Both rear wheels still on the ground it surprised me a little that there still was no noise. After I got the driveshaft down it was obvious the yoke had been moving loose on the pinion. What had happened was the vibrations you were pointing out had worked the yoke loose and wore every spline off of the yoke. Being a low buck repair we replaced the yoke as it appeared the splines on the pinion were fine. The truck was sold or traded and was someone else's nightmare. I saw plenty of U-joints destroyed but the pinion was a first. Get those angles corrected!
Great walk through of the valve working system and drive line angles,both very interesting and important for smooth and Safe operation and comfortable ride ,ain’t nothing worse than a drive line whip on a sore body!!!!
Awesome explanations! IIRC that valve you replaced also works as an anti-compounding valve. On the driveline, another issue to watch for, especially on SPL slip yokes. That blue plastic coating that is supposed to keep the splines nice and slick,,,, well, when it rust jacks, the slip joint, slips no more. That'll take out pinion bearings, or knock out carrier bearings.
Fantastic explanation of the driveline geometry and the air brake design JC. Great you turned the corner and the chassis is done, ready to receive it's body again. Nice work, great video. Work safe, stay warm! Doug@ the "ranch"
Great video, even though I’ve been watching you for a couple years now I still always seem to learn something. My dump truck has a leaky pinion seal... I see one of those tiger tools in my near future lol
Hey love the videos, you the Man! I have a couple of questions regarding the modifying of trucks for COMMERCIAL USE.. Although I feel my questions would be more of a conversation and truly one that I would really like to have let me start by asking this..... if someone was to build a custom truck mostly from factory parts, so a frame from one truck a engine and Trany from another as well as differentials and suspension from other donors vehicles, all done correctly. Correct bolts, standardized practices for safety and industry compliance. And the weakest component would have a rating of a vehicle with a GCWR of 50K and the body/cab that was used is like from a lite duty truck. How can you get that rated for the purpose Of DOT? .
here it would be an "assembled vehicle". it would have to inspected by the state highway patrol. it has to meet the minimum safety requirements. the "manufacture" would set the gvwr. guess who the :"manufacture" would be in that situation.....
Thanks, I guess that would be me if I was the main builder. Or dose it need to be a registered truck up-fitter? Would I need to have a sticker maid up for the the rating I deem appropriate and was excepted?
Hey JC I really like you channel. I'm learning a lot. I have a question. I see you shortening truck frames- have you ever lengthened one? I have a 154 WB Ford F800 (1989) and was wondering. Keep up the great work.-
@@j.c.smithprojects If you have a short wheelbase and need a longer one for say a flatbed. Do you use a welded frame and a doubler? Do you have a video of this?
I weld a frame section in place and i put in a outside double frame along with a "liner". i use bolts to make a mechanical connection to back up my welded connection. look at my channel under playlists. there should be a series call beverage truck. i showed how i did it. it is not a how to, just entertainmenty.
the u joint gets into a "bind" when each dross section is at its rotations point. this slows it down. once past that point, it speeds up again until, the next cross section hits that point.

275👍's up JC thanks again for taking us all along with you for the rest of the build
👍 from the Netherlands 🇳🇱 in a hard Lockdown and curfew
Thanks fot the video .
Stay Safe and Healthy !
take care of you and yours!
Good explanation on those brakes. And that Tiger Tool does the job.
Great explanation of measuring and correcting drive angles. Thank you for sharing.

That yoke puller makes that look easy!! Take care Mr and Mrs JC

your explenation was excellent, learned something new today, greetings from Belgium

Work safe, stay warm!
Doug@ the "ranch"
seems like i just get one done and the next one is pulling in before i get a chance to breathe.
Awesome video as always. I sure do learn a lot . Thanks for explaining the drive shaft angle.
I wish I could justify buying some of the different tiger tools. That drive line kit and the press kit you showed in a earlier video are slick
i am very pleased with them for sure.
Great video, even though I’ve been watching you for a couple years now I still always seem to learn something. My dump truck has a leaky pinion seal... I see one of those tiger tools in my near future lol
Awesome video and very informative. Thank you.
That Milwaukee is like butter taking off them nuts and bolts 👍
Thanks for the air brake system functionality overview.
Very clean build sir.
Enjoyed the video as always. Stay warm and safe.
Good job on the truck like your videos
Interesting theory on drive angle
Thats interesting about the modulator valve
Another great video
Good post and work sir

Keep up the good work buddy
Great video thanks for sharing.
interesting on that spring brake modulating valve I don't know that iv ever seen that on class 8 stuff.
i dont recall seeing it on the freightliner columbias i was just working on either
Thanks, I guess that would be me if I was the main builder. Or dose it need to be a registered truck up-fitter? Would I need to have a sticker maid up for the the rating I deem appropriate and was excepted?
I have my air brake endorsement but only drove once for my test. It’s been a long time...
Great explanation
Nice work, so what did you use to take off the pinion nut?
How do you account for weight on the truck when setting up the driveshafts? Great video! Thanks, Mike
air ride suspension has a leveling valve. it keeps it at the same ride height.
@@j.c.smithprojects Ohh cool. Thanks much!
Great explanations
What happened to the Chevy 350 engine rebuild videos?
Nice job 👍
Looking good!
How ya all doing tonight .?I hope well and till next vid Godbless
Have you ever mess with a one ton Chevy or GMC rear brakes that are Disc That has the emergency brakes on the backing plate
YES

@@jontrudell7529 Is your name JC?
i have.

Well explained
I could have been first but watched the video instead.
I’m a bit confused about the speed of the u joint. Is it the caps on the end of the joint that change speed as they rotate on the stub?
the u joint gets into a "bind" when each dross section is at its rotations point. this slows it down. once past that point, it speeds up again until, the next cross section hits that point.
I think the angles are off on my front axle shaft , I noticed that the other morning driving to work in 4x4
i bet you get a bunch of snow drifts out your way with all those fields around you.
Wassup JC
Have you tried to just punch a hole in the pinion seal surface and put a screw in it and just pried out? All the best from Canada.
i have. this one was so rusty, it just fell apart.
Too bad you weren’t closer. I have a international 4300 that’s been nothing but problems.
Don't be sending cold weather down here
Thanks for explaining all of brakes and angle
