It sets the point at which the brake band applies..The longer bolt there is the clutch freeplay adjustment..To tighten the band for more apply pressure , there is a small cast cover on the side of the steering clutch housing right above the track.. Inside this cover is a near vertical bolt with a 13/16" head..Turn the bolt clockwise to tighten the brake band..It goes in half turn increments..With this adjustment and the "timing bolt" you should be able to dial that brake in..Should be no oil or water in there..As I stated before here; ALWAYS cover the back of the machine when not being used..From the dashboard to over the back of the fuel tank.."If a bird flies over the machine and craps , it will find it"s way into those clutches"..

Every thing feels good as far as linkage but the machine wont turn at all to the right. [Reply]  [No Email]

The first thing to do go through the steering clutch adjustment procedure (both sides). If anything in the linkage is messed up, or the brake band isn't going into detent it will be clear when you're adjusting it. If everything appears to be working, then you may be able to break that clutch pack free just by getting the dozer blade up against something solid and spinning the track while holding the left lever back while working the right lever. If this doesn't work, you'll have to pull that clutch to find out why it won't release. Make sure to pull all 4 drain plugs on the clutch housings regularly to get condensation and/or any leaked oil out of there. [Reply]  [No Email]

It would be braking and trying to run at the same time. [Reply]  [No Email]

I know this because I've operated it without noticing that the parking brake was set before :) If there's a little bit of water and oil splashing around in the clutch housing, all the more so.

Pulling back even further THEN starts to apply the brake. So, when you say you pull back and nothing happens - it sounds like - at the least - the brake is not working at all. If the brake WAS working, and the clutch was disengaged - that track would stop. If the brake is working, and the track is NOT disengaging, the engine would start to labor or stall. Try pulling both levers all the way back. If the machine stops, then you know the right-hand side is disengaging. Then, with the left back, let the right go. If the right track moves, then that side is also engaging. At this point, you'll have some idea of what is, and is not working. If just no brake, maybe just needs adjustment or some linkage got unhooked. [Reply]  [No Email]

Take the top off steering clutch cover & look inside for grease in the bottom caused by leaking seal. Should be dry down there. Used to leave the drain plug out of the bottom so any grease getting in there drained before it got on clutches. Had to remember to put plug back in working in mud & water or sand, mud, etc. went up thru the hole & covered the clutches. [Reply]  [No Email]
