2. Check vehicle charge line cables for damage, dirty connections and loose connections.

If Liftgate battery box is installed, check for damaged battery cables, dirty cable

connections and loose cable connections in battery box. Replace damaged cables, clean

dirty connections and tighten loose connections.

3. Check for bent parts on the Liftgate that could interfere

with normal operation.

4. Verify that relief valve pressure settings are correct. Refer to relief valve pressure

setting procedure. If pressure settings can’t be corrected or if pump runs

hot and excessively noisy, replace pump.

5. Remove pump assembly from reservoir (FIGS. 53-1 and 53-2). Check if pump ﬁ lter

is clogged. Clean clogged ﬁ lter and ﬂ ush contaminated ﬂ uid from reservoir. Replace

spin-on ﬁ lter in pump box. Reinstall pump/motor assembly.

1. Check for unequal cylinder operation (lagging cylinder ﬁ rst).

 GRAVITY DOWN LIFTGATES: Lower the platform to the ground. Disconnect the

RETURN HOSE at the bottom of each column. Place a large container under

cylinder to catch ﬂ uid. Set control box toggle switch to UP position to raise platform.

Check if ﬂ uid is streaming from the ﬁ tting. A few drops of hydraulic ﬂ uid is okay;

however, if ﬂ uid streams steadily from the ﬁ tting, replace piston seals.

 POWER DOWN LIFTGATES: Raise the platform to bed height. Disconnect both

bottom POWER DOWN RETURN HOSES at the “T” connector between pump

box and bottom of each cylinder. (Refer to POWER DOWN HYDRAULIC LINES

IDENTIFICATION in this manual. Place a large container to catch ﬂ uid from both

hoses. Set control box toggle switch to UP position to raise platform. Check if ﬂ uid

is streaming from the hoses. A few drops of hydraulic ﬂ uid is okay; however, if ﬂ uid

streams steadily from a hose, replace piston seals in the cylinder connected to that

hose.
