 PART 3

 

Symptom

 

Fault

 

Possible Solutions

 

Oil leaking from 

 

between slices of the 
valve. 

 

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.

 

Clamping bolts loose.

 

Check bolts through valve tightened to correct 
torque specified in the valve manual. 

 

Separation of slices in valve block as a 
result of reverse oil flow (only when 

 

connected to a double acting spool 
valve).

 

Fit return pipe to free flow return on tractor, or fit 
check valve on outlet port to prevent 

 

reverse flow.

 

Interface seals damaged by either of the
