Possible Solutions
Oil leaking from

Internal pressure in valve.
Check return line hose connected and that return
line flow is not restricted by damaged fittings or
the tractor spool valve.

Check bolts through valve tightened to correct
torque specified in the maintenance section.
Separation of slices in valve block as a
result of reverse oil flow (only when

Fit return pipe to free flow return on tractor, or fit
