Section 9 Hydraulic System
Model 6036/6036T S/N 9B0500 thru 14833 9-59
Warning
Relieve hydraulic pressure before servicing any
hydraulic component. Escaping hydraulic fluid
under pressure can penetrate the skin causing
serious injury.
Warning
Wait for the hydraulic fluid to cool before servic-
ing any hydraulic component. Hot hydraulic fluid
can cause severe burns.
IMPORTANT: Protect the finish on the rod at
all times. Damage to the surface of the rod can
cause premature seal failure.
5. Pull rod (3) and attached parts straight out of
the tube.
NOTE: It may be necessary to apply heat to break
the bond of the sealant between locknut (5) and
rod (3) before the piston can be removed. Refer
to paragraph 9.5.a.
6. Remove locknut (5), piston (2), and gland (4)
from the rod (3).
7. Remove rod wiper (6), U-cup seal (7), O-ring
(8) and back-up ring (14) from the gland.
8. Remove O-ring (9), wear rings (12), piston
seal (10) and expander (13) from the piston.
9.5.11 Steering Cylinder
(S/N 3102 & After)
a. Removal
1. Engage the park lock, place the travel select
lever in neutral, and stop the engine.
2. Operate the hydraulic controls after the engine
has stopped to relieve any trapped pressure.
3. Disconnect the hydraulic lines from the
steering cylinder and cap or plug open con-
nections.
4. Remove cotter pins (1, Fig. 9.31) and nuts (2)
securing the cylinder socket assemblies (3) to
carrier (4) and knuckle (5).
5. The steer cylinder socket is a taper fit in
knuckle. Use an impact fork to release the
socket from the knuckle.
6. Remove the cylinder from the forklift using a
strap sling and hoist or other suitable lifting
equipment.
7. Measure the total length of the fully retracted
cylinder with sockets in place and note or
record the distance. Loosen socket clamp and
unscrew the socket assembly from the cylin-
der (3).

b. Disassembly
1. Remove all dirt and grease from the steering
cylinder.
2. Determine the direction that the gland (4, Fig.
9.32) will be turning when it is removed so
that the wire retainer (11) will feed out through
the tube hole.
3. Using a sharp object, such as a screwdriver,
pry up one end of the lockwire from its hole in
the tube (1).
4. Using a wrench, remove the gland allowing
the wire retainer to work its way out of the
tube.
