I have a 9U that I posted about previously. it appears the steering clutches are working, but the right hand brake won't work in reverse and is very marginal in forward. I am guessing that the parking brake will engage an prematurely wear down the lining, any experiences? Long story short, the dozer has a D6N winch and it appears the winch must be removed for reworking the brakes. However, I believe I can just inspect from the top if i remove the seat / tank. I would like confirmation that the first thing to do is remove the seat, inspect and evaluate.
Second the main clutch seems odd. I have put about 5 hours on the dozer and the clutch worked great until recently. The handle has become much harder to pull and does not seem to "break over" during the movement. If I pull back too hard, there is a quick grind from the area of the clutch. I am thinking that I somehow bent something. I have put three quarts of 30wt non-detergent oil in the clutch and it still does not register on the dip stick. This should not affect the operation of the clutch, probably only the life of the plates. I am in the process of cleaning up the area around the inspection / adjustment panel behind the clutch. Any thoughts?
