Not sure if I should post here or start a new one. I have a C20B - looks the same as this. The driveshaft seal is leaking - red fluid in both sides of this assembly. I've pulled the whole assembly out and see the seal behind a plate with four studs. Can't seem to get the plate loose. Is it just a cover plate or is it a capsule holding seal + bearings? I think I can pull it with an internal puller w/ slide hammer. ANyone been in that far? Is there another way to get that plate loose?

Thanks to all for your help. I successfully (and safely) have rebuilt the brakes.

I stopped by and looked and the stud nuts are waaay inside. Thanks for mast raising info and blocking, will do that when I have my helper to do the work. After that, next problem to tackle is that mast raises, but does not lower...

Raising the mast and chaining and blocking it up SAFELY SAFELY SAFELY....will allow better access to the nuts on the back side of the hub assembly....they are hard to see with the mast and carriage lowered down...reread...SAFELY SAFELY SAFELY!!!!

Thanks, I will look for those when I go back to the shop tomorrow. Also thanks for the manhandling info.

Looks like you only have 5 bolts out. You have 5 more to go. There are 5 NUTS that also hold that on. Look in from the front side of the lift, more towards the middle, and look for the nuts that have 3/4" hex heads. 2 are on the underside also. They are going to form a full circle shape of fasteners that hold that on.

The bolts in the front there were to attempt to twist the assembly with a pry bar, same results without them.

tell us how many bolts you did take out, and recognize there may be some longer threaded studs that are also part of what holds this unit together. you will remove the nuts to these studs.
Do not pull both sides at the same time, and you should use a floor jack (and someone who has done this particular job on one of these trucks) to support the unit as you pull it out, it will be heavier than expected, and awkward, and the second it pulls loose. it will want to shift on the jack, it can take your manhood, your fingers and toes, and your internal organs with it, if you are not really aware of how and when it will shift.
Be careful doing this job. I never send someone to do one of these who has not done it before with close supervision

I can't find any more bolts. I found an old Army manual for this model and seems that I have followed the tear down procedure (not a lot of detail). I will try to post some pictures of it, that might help.

Are you sure you have all the bolts and nuts removed, bolts in the wheel well area and nuts underneath and around to the front? It should come off easy.
