Hey guys I have done some cut and paste from another forum. I need help. I'm about to loose my mind.
I just replaced the lift and tilt spool seals on my 763. I spread 1 load of dirt. The pedals were working very smoothly. Then on the last bucket of material, the tilt spool was hard to push with my heel. When I got it to press down, it stuck. (kind of like detent) I had to return it to center with my toe. It is harder to push at higher rpm. No leaks. I put some cheap r and o hydraulic fluid in it to get it on the trailer originally. That fluid is still in the machine and its a little low but not too low and no cavitation/foaming. What gives? Why would it all of a sudden start acting up?
New info about this. It is the tilt spool. I have tried everything!
Filled up with fluid. I have narrowed it down to the centering spring, I think. I removed the interlock and tried it, still sticking. (btw, when i say sticking i mean, rough pedal operation and it sticks in the tilt up position, I have to rock the bucket a little forward to "unhang" the pedal. It makes it impossible to finesse the tilt) I turned the spool 180 degrees, still sticking. It seems that every time I remove the centering spring cap and re install it, the operation is just right for a short time (10 minutes) then it goes back to sticking and rough throughout the pedal range of motion. I put a little grease inside the cap which did nothing to help. There are no scars inside the cap like its been rubbed or anything. I can't figure this thing out! Any more ideas guys?
