Here is a cross section view of the booster. The hydraulic control spool is burried pretty far back and is pretty well protected. Rod can get corroded and effect operation but in general bad boots don't seem to have much adverse affect.

Had a chance to get out to the cat today. First thing I checked was the booster resevoir. There was no oil to be seen.. have to top that up. Yet the lack of oil would that hold the clutch open? Second, when I removed the cover holding the boots to the booster the boots were in two pieces. Below each boot was a wire ring, could these rings simply be from the boot bellows? I can't see any other reason for those rings to be there.

Ideas?

The rings are retainers for the boots (one piece)
Depends on how dry and for how long before clutch operation could be affected by the lack of oil. Manual operation of the clutches is back up in the case of hydraulic loss or failure but effort is considerably harder.

Hi guys im new to this forum i own a mobile heavy equipment repair bizz im looking at a job of removing the right side steering clutch's on a D6-9u because there locked up ive never done this im just looking for a rough run down on how to start taking it apart? does the track on the right side have to come off? any info would be appreciated thanks

No, the clutch can be unbolted and lifted out the top using the brake band as a sling. However you will need to be able to move the tractor forward or back a little to rotate the steering clutch to get to all the bolts.

Hello i have a traxcavator that looks like the same set up as what u have mine wouldnt unlock one side when u wanted to turn what it ended up being is the casting that holds the ring gear bearings was broke and aloud the spool to move to one side and it wouldnt release that clutch pack i would have someone move the levers and see if its releasing or if u have other issues

Is another one and done post? No activity since the original post by Dittmer. If you come back there is a lot more.
