Lift Cylinder 1900 SRM 964
DISASSEMBLE
CAUTION
Lubricate the seals and O-rings with clean hy-
draulic oil before assembling. Make certain to
install spacers, if any were removed.
1. Loosen the gland nut. Extract the piston, gland
nut, and rod from the cylinder. See Figure 13.
2. Disassemble the nut and piston from the cylinder
rod. Remove the spacers, if used, and slide the
rod out of the gland nut.
3. Remove all seals and O-rings.
ASSEMBLE
1. Install the seals and O-rings as necessary into
the gland and piston after coating them with
clean hydraulic oil.
2. Carefully install the rod through the gland nut.
Install the piston, spacer (if necessary), and the
lock nut. Tighten the lock nut (lubricated) to
150 N•m (110 lbf ft).
CAUTION
Make certain that none of the sealant (sealant
2064554 or equivalent) gets into the cylinder.
Allowing sealant to get into the hydraulic
system may cause damage to the components
within the hydraulic system.
3. Carefully install the rod assembly into the cylin-
der. Apply sealant 2064554 or equivalent to the
threads of the gland nut. Tighten the gland nut
to 27 N•m (20 lbf ft).
INSTALL
1. Align the bottom of the cylinder with the frame
and install the bottom clevis pin.
2. Install the roll pin to retain the clevis pin.
3. Align the top of the cylinder rod with the frame
and install the top clevis pin. Install the roll pin
to retain the clevis pin.

8. Connect battery and turn the key switch to the
ON position.
9. Operate the hydraulic functions several times to
purge air from the hydraulic circuit.
10. Test lift truck by lifting and lowering a load sev-
eral times. Check for leaks.
11. Check hydraulic oil level in reservoir and fill to
proper level. See Hydraulic Reservoir, Table 1.
12. Install the drive unit compartment covers. See
