REMEDY
a. Replace pressure switch.
b. Clean and check relief valve.
3. Problem
- Powerpack shuts off before gear reaches position.
PROBABLE CAUSE
a. Binding or jammed gear retractor, which causes pressure to build up (and stay up), and pressure switch
shuts off powerpack.
REMEDY
a. Repair retractor.
4. Problem
- Powerpack cycles on and off after gear is in position.
PROBABLE CAUSE
a. Internal hydraulic leak.
b. External hydraulic leak.
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.
c. Poor motor.
d. Worn pump gears.
