Need some clarification on how the steering on a CAT D3B works.
I understand that when you press a steering clutch pedal you activate the steering clutch valve. When the valve is open hydraulic fluid flows to the piston inside the steering clutch case. This pushes on the rod which pushes the arm of the yoke. When this happens it "opens" the clutch pack. WHY does this cause the clutch pack to disengage???? Also, I know that there is a "stop" bolt that is to be set at a certain distance from the sideway of the case. What happens is the clutch pack opens WIDER that what is specified???
These probably sound like silly questions, but I'm finding I'm wearing brake bands like crazy and I'm not sure WHY? Dozer is only used around my property and had it for 5 years and went thru 3 bands that had to be relined. Seems like alot.
Thanks to all who respond!!!
