REMEDY
a. Verify leak is not external by checking fluid level in reservoir and looking at couplings for oil leaks. If no
external leaks are found, disconnect and cap off the hydraulic actuators one at a time and find the leaky one by
process of elimination. If isolating entire system still indicates internal leak, power pack check valve (located in
pressure port of pump) is bad and needs replacement or reseating.
b. Visually inspect lines, cylinders, and hoses and replace as necessary.
5. PROBLEM
– Power pack cycles on and off during gear cycle.
PROBABLE CAUSE
a. Binding in retraction unit.
b. Pressure switch cut off limit too low.
REMEDY
a. Investigate for free operation. Check gear that retracts last.
b. Replace pressure switch.
6. PROBLEM
– Slow gear operation cycle (considerably longer than 30 seconds).
PROBABLE CAUSE
a. Plugged oil screen.
b. Poor electrical connection to motor. Check ground.
c. Poor motor.
d. Worn pump gears.
REMEDY
a. Clean intake screen located inside reservoir tank.
b. Connect motor direct to 12/24 volt source and note operation poor, motor needs overhaul.
c. Covered in (b) above.
d. Replace pump
7. PROBLEM
– Circuit breaker pops during cycle.
PROBABLE CAUSE
a. Wire connections bad or corroded.
