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.
