Needing some help with a 450c I recently purchased. I bought the dozer knowing it needed steering clutches and brake bands. I just finished changing steering clutches and brake bands on both sides and now it turns perfect just as she should. The problem I have now is that it has no power in reverse. It will move if its in gear 1 and on flat ground but don't even attempt to climb a hill. I went through the entire sequence of clutch and pressure adjustments (followed Roy Suomi's post on how to do it). Ive managed to get my free play just right and my pressures dialed in to 185psi all except for reverse. Its 185 in neutral, L,and H but in reverse its about 125. Ive changed hydro filter and cleaned screen in side of transmission. Changed fluid twice to get it good and clean because the old fluid had a lot of water in it and was milky. I just wanna get this thing working like it should so I can use it. Ive enjoyed working on it but its starting to get frustrating because I want to be able to use the thing. My assumption is its gotta be something in the transmission at this point with my pressure only being low in reverse but I just need to know what to do next. Im assuming pull the top cover? Once top cover is pulled what do I look for? I sure would appreciate any advice.
