SECTION 3 - CHASSIS & TURNTABLE
Lubrication Information
GENERAL PROPERTIES
Lubricant should be petroleum based gear fluid containing
anti-oxidation, anti-foaming, and extreme pressure additives.
The lubricant should have a minimum viscosity index of 95 cst
and maintain a minimum viscosity of 40 cst under normal
operating conditions. Some applications require special con-
siderations; consult the JLG Service Department for additional
information.
The table below lists recommended viscosities for various
ambient operating temperatures. Recommendations are
based on temperature rise of 50° to 100°F at normal operating
conditions.

Footnotes
1. For operation in this ambient temperature range, synthetic oil is recommended with
a pour point of 10°F lower than the minimum ambient temperature.
2. For operation in this ambient temperature range, synthetic oil is recommended for
proper lubricant life at elevated temperatures.
MAINTENANCE
Oil amounts for each series of Torque-Hub drives are indicated
in the appropriate series literature. An initial oil change should
be made after the first 50 hours of operation. Subsequent oil
changes should be made at 1,000 hour intervals or annually,
whichever comes first.
Oil temperatures should be not higher than 71° to 82°C
(160° to 180°F) for continuous operation, and no higher than
93°C (200°F) for intermittent operation. For special applica-
tions, consult the JLG Service Department.

Motor Removal
Refer to Figure 3-26. and Figure 3-27.
1. Place unit on bench with motor end up.
2. Remove magnetic Pipe Plug (1P) and drain oil from gear-
box.
NOTE: Record oil condition and volume.
3. Remove Hydraulic Tubing Assembly (35) by loosening
fittings on both ends of tube with a wrench.
4. Using a wrench, loosen jam nuts on Elbow Fittings (30)
and remove fittings from Brake Housing (6) and Motor
Control Valve (32).
5. Remove O-ring Pipe Plugs (23) from Motor Control Valve
(32).
6. Remove Motor Control Valve (32) from Motor (31) by
removing the four Bolts (21) and washers (22).
7. Remove O-ring (99) between Motor Control Valve (32)
and Motor (31). Discard O-ring.
8. With unit resting on bench with Motor (31) end up,
loosen Hex Bolts (29) and remove Lift Lugs (28) from the
Motor (31).
9. Pull Motor (31) straight up and remove Motor (31) from
Brake Housing (6).
10. Remove O-ring (26) from between Motor (31) and Brake
Housing (6). Discard O-ring.
