Learn from the best in the industry. These step by step videos are intended to help the diy drivers out there and the young man or woman who wants to learn some of this stuff without having to pay some technical college. In these videos we try to hold nothing back so everyone can get a good grasp on what to do and what the next step will be when working on these units. Our main goal here is to try show young and old people that this stuff isn’t that hard to do. We hope these videos help. Thank y’all very much for watching! Have a good day!
I always thought that a clutch brake that didn’t work well was a clutch brake that had just worn out it’s friction material. Good to know that a clutch adjustment can fix this.
Great video’s. as a new driver, I’d love to see more info on where exactly the splitter air-solenoid is actually located on the box and how it works. Cheers Guys.
Mine makes that sound only when I’m in low gears if I let off the fuel the rpms go to idle and make that grinding noise, also it does that in reverse pain in the ass to backup I thought I needed a whole new transmission, thanks for the info.
Hello from Russia guys, please wear gloves to protect your hands because it is your health. I work as a logging truck driver and I fix my truck by myself most of the time and I assembled a 10 speed gearbox on my own and it took me a lot of time and effort, video tutorials on youtube helped me. Keep making these videos I think there're a lot of people who want to watch it, best wishes.
Ok so what you’re saying is, if the engine is running and air is supplied to the truck, it’ll be ok because it’s spinning and splashing the oil around as it should be?
Can you help with a hint pls. Ive the same box in Hino tipper and experience grinding on 5th and 7th. been quoted 10k Australian to recondition box only. Does this seem reasonable? Seems like a lot of money to me. The truck cost me 50k Australian with less than 150 000kms on clock. Any advice would help . Your work is impressive.
The CAT C7 is one of my favorite Caterpillar motors. I love the ones used in the 1st gen/04-07 BlueBird Visions and BlueBird All Americans, love the engine!
If the pinion bearing preload is so loose that you have to hold it with a pry bar to check backlash and drag it by hand to squeeze out pattern grease, then it is to loose. Preload is critical to the life of the unit. Also double check the ring gear runout by putting dial indicator on smooth back surface of ring gear, turn. Max allowed is .008" on the 404 if too much runout, unbolt diff cases, rotate 180° reassemble. It's a quality of manufacturing issue. Most good mechanics can build a rear that works but industry experience builds a better unit
My rt14614 Eaton 15 speed is sending air from my deep reduction cylinder to my shifter making it leak but when I put my splitter in the forward position the air stops but I have no deep reduction gears why is this happening
Have an 8LL. Gear travel is loose and now it has excess travel to the point its lost the gear pattern. I have gotten it back into the gear pattern but now cannot engage 3/7? Thoughts?
You can use a brass wire wheel with a drill and smooth out that rusted cylinder. I did that to mine and its still going 3 years later. Get a new piston kit tho and grease it really well
Mine will go into 1st gear but grind real bad going into every other gear. Do you think the clutch brake is not stopping the transmission? It's pushing the throwout bearing into the pressure plate.
This is not a knock on what you do, I have a few genuine questions. One, you did not use the standard tightening sequence for the main bearings, (inside to outside), do you feel that is not necessary? There was no use of plastigage to check mains or rod bearings for clearance, again do you feel unnecessary? Again, the torque pattern for the head seems odd, I really don't know if this is spec for this particular engine, I have never built this engine, but it seems odd from all the engines I have built.
I've rebuilt the C7 engine at least 10 times, I thought they assembled really well. The common failure I saw on most of them was piston failure, I think they were aluminum one piece and the skirts would some how get destroyed, causing really bad blowby. Nice touch changing the injector harness, those were always hardened and brittle.
No sir the input shaft has reverse spirals cut into the shaft that when the engine is running pulls the oil back into the case. There is however a shipping seal located there from the factory it is not needed during a repair or replacement of the input shaft. The shipping seal does nothing but keep oil from leaking past the input shaft when the transmission is in the vertical position during storage.
@@etrtruckcenterenginedrivet8918 Thankyou Sir :) Been watching videos to see if i can learn enough to rebuild a 9 speed which wont downshift 5th to 4th , Many experienced mechanics dont attempt to repair these transmissions , They tell me "Send it out" ;)
Exceptional. I've rebuilt my share of motors and really appreciate the methodical approach, clear instructions and Attention to detail. Liked and subscribed.
