Moreauville LA | Running a 635F on a 9860. Noticing lately it has been getting slower to raise
Yesterday was the worst. Not as bad when cool. Checked pressure at header valve by accumulator and went to 3100 at WOT when header lifted completely and machine cool.
Wont raise at idle Very little at mid throttle.
Does the main hyd pump get weak or they're either good or bad?
I am aware of the shimming the spring to raise pressure but it is within spec.
Worn spools in the header valve? Or coils not pulling enough; at $425 each? | |
