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.
