806 woes

jdv · Jul 7, 2014

I am working on the brakes on an 806D no t/a and had a some questions for all of IH gurues. I have the everything off on the right side, and the discs look as good as the new ones, just all oily. My question is can I clean them up in solvent(gas or diesel) and not worry about it loosening the fiber off the discs? My next question is about the shaft that the brakes fit on. The shaft has some in and out play, whitch I"m sure is the cause of the problem. Is there a way to access this shaft from the top and tighten up the shaft, or do I need to split the tractor to get to it? Thanks for all your help. I"ll include some pic"s of the old beast feeding hay this winter.

I've cleaned brake linings up before you need to make sure to get cleaner that is specifically made to be used to clean the actual linings I've cleaned up clutch disks before

Not sure what the brakes look like on an 806, but I've always cleaned oily brake linings by setting them on fire with a torch. (off the tractor of course).

Might sound extreme, but it works. You don't have to worry about them getting too hot - they're made for high heat.

It draws a lot more of the oil out than simply cleaning them with a solvent.

Then finish with brake cleaner once they're cooled off. (don't get brake cleaner hot - it can kill you, or at least the old stuff could)

Of course your bigger problem is putting new seals in to stop the oil.

i dunno if it's "correct" or not, but i've found that starting fluid and mineral spirits are both great solvents for cleaning up oil. i'd hesitate to set the disks on fire, cause you don't want to warp the steel part. maybe just make sure it doesn't get too hot.

if you get all the free oil off the surface, i wouldn't worry too much about the oil that is soaked in, at least on a "working" tractor. the brakes might end up being noisier than with new, clean disks, but they'll work ok.

you can see your friendly CNH dealer or aftermarket such as a&i for a brake seal kit. there are two big o rings, 1 smaller, and a lip seal for each side.

make sure to check out the self-adjusting screws, that the tab prevents them from backing up and that they turn freely.

also check out the 4 return springs- they can loose some of their spring with time and heat/cool cycles.

as for the pinion shaft, can't help ya, never had any trouble with them.
