10. 1400 SRM 46 Description
General
This section contains description and repair procedures for the differential. There is a Specifications section
and a Troubleshooting section at the end of this section.
Description
This differential is fastened to the drive axle hous-
ing of the lift truck. The differential provides a sin-
gle-speed reduction for an increase in torque to the
drive wheels. There is a housing, a ring and pinion
gear set, and the differential assembly. The ring gear
transfers power from the pinion through the differen-
tial assembly to the axles. The differential assembly
permits the drive wheels to rotate at different speeds
during a turn. See Figure 1.

REMOVE
NOTE: The repair procedures cover all units unless
otherwise indicated.
Differential Carrier From Axle Housing,
Remove
NOTE: The differential assembly can normally be
removed without removing the drive axle. On some
trucks, including the H7.00-12.50H (H150-275H),
the drive axle must be removed to remove the dif-
ferential assembly. If removal of the drive axle is
necessary, see the Drive Axle service manual for
your lift truck model.
1. Remove the mast. See the Mast section for your
lift truck model for the removal procedures.
2. Raise the end of the vehicle where the axle is
mounted. Use a jack or other lifting tool, and
place safety stands under each side of the axle.
See Figure 2.
WARNING
Block the wheels to prevent the lift truck
from moving. Support the lift truck with
safety stands. DO NOT work under a lift truck
supported only by jacks. Jacks can slip and
fall over. Serious personal injury can result.
3. Place jack stands under each spring seat of the
axle, to hold the lift truck in the raised position.
