d6 dozer power loss on one side

gilroy · Jan 14, 2009

hey all, Im trying to help my neighbor with his dozer. Basically, the right side seems to be lacking in power, especially under load, while the left side runs very well. I"ve adjusted both sides steering clutches and brakes to spec. Yet the dozer seems to drift right when running, especially behind a pile of snow, and when you try to turn left, there is almost no power to the right side, it just stops. also, even after adjusting the clutches the right side clutch lever seems to be a lot softer of an engagement then the left side. The dozer, I beleive, is roughly 50 years old with hydraulically controlled clutches of the dry, multiple disc type. I figure that there has got to be either leakage in the hydraulic cylinder holding the clutch from complete engagement or weak clutch springs, because i know the brake is not dragging. Any help would be much appreciated as I am not much of an heavy equipment tech.

You should post this in the crawler section on this same forum. I could give you a lot of info, but it probably will be wrong. My crawlers don't have any hydraulic stearing, all manual. Stan

Your steering clutchs have oil on them. Dump in some kerosene on the right side and move dozer back and forth pulling the right steering clutch lever, this releases the disc and helps clean the disc and steel disc. Drain out the kerosene and see if it helps if not repeat. You might have woren out steering clutches which can be expensive as you know.

What model D6 is it?
If it's one of the 8U/9U's or similar check to be sure the steering levers are returning all the way (eg. shot bumpers) as one side will effect the others operation. Beyond that if it's not adjustment check for oil soaking or worn out steering clutch.
