This morning I got started pulling my transmission to clean the clutch and flywheel after the transmission leaked all over the place from being overfull.
BOY AM I GLAD I DID!!!!! There are people who said that it would be fine by just spraying brake cleaner in the access hatch and cleaning up the clutch that way. I did that on the way home from Sparta with the truck and it worked. But I am here to tell you, especially if it's a GL truck or anything unknown. You're better off to take the extra work and pull the transmission if need be.
I started the day by draining the fluid from the tranny, and marking the transmission to transfer case propeller shaft for removal. I also marked the propeller shaft going to the front axle, I probably could have gotten away without removing it, but I felt better taking one side of it off and setting it out of the way. After that I pulled the passenger seat and tunnels out of the cab. This makes it a lot easier to work on the transmission to transfer shaft.
The first reason I'm glad I decided to undertake this project was very evident when I puled the transmission to transfer shaft. ALL 8 BOLTS IN THE SHAFT FLANGES WERE LOOSE!!!! THe truck has a brand new, or at least newer transfer case in it, I guess someone decided they didn't need to tighten up the propeller shaft bolts since it's so short. After that I was ready to pull the tranny. I got my lift rigged and pulled the transmission loose and lowered it to the ground, where I got my next surprise. One of the spring retainers for the throw-out bearing was lying on top of the access panel when I opened it up on the way back from Sparta. The other one was gone as well. Luckily it was stuck to the side of the flywheel in a little of the muck left behind from the oil and clutch dust. Then I looked at the pressure plate to remove it. About half of the bolts in the pressure plate were LOOSE AS WELL!! So I removed the pressure plate and looked at the clutch disk...IT WAS TRASHED!!! apparently, the transmission is a fresh rebuild or fairly new as well, and when they put it on the decided not to look at the clutch, I wish they would have!!! I spent the next hour and a half trying to track down a truck shop that would have one on hand so I could put this thing back together. I did manage to find a civilian part number and manufacturer for the clutch disk, but nobody had one, so I had to order one and now I wait!
After the phone calls to find a clutch disk, I pulled the flywheel off to change the rear main seal while I was this far along. Low and behold, I must have an older version of the LDT because it does not have the rear main carrier like other people have mentioned. If it was not for my years of experience working in industrial maintenance, and dealing with f...f...fouled up situations I would have asked myself, "What the he!! do I do to get this thing out of here?" But I had some tricks up my sleeve, so it came out whether it wanted to or not, Luckily the crank looked really clean and smoth, so the new one went back on easily, then the flywheel was remounted. Now I'm at a standstill until Monday, when the new clutch disk will arrive (hopefully).
Don't let anybody talk you out of doing a major job like this just because your clutch isnt slipping. You never know what you'll find wrong with an older truck. Especially one that you don't know the maintenance history of!
