Description
General
This section has a description and the repair procedures for the planetary gear axle.
Description
The planetary axles incorporate a single reduction
carrier/differential assembly with hypoid gearing.
The final reduction is a planetary spur designed
gearing built into the wheel hubs. See Figure 1 and
Figure 2. The axles have only cast housings. See
Figure 3 and the section Differential for your lift
truck.

Operation
Operation
The planetary axles permit the hypoid gearing of the
carrier and the axle shafts to carry only a nominal
torsional load. At the same time, they provide the
highest practical numerical gear reduction at the
wheels.
• The hypoid pinion and differential assembly of the
first reduction supports the roller bearings.
• A hardened precision spacer between the inner and
outer pinion bearings adjusts and maintains the
pinion bearing preload.
• The positioning of the threaded adjusting rings in
the carrier leg and cap bores adjusts and maintains
the differential tapered bearing preload.
• The teeth of the floating sun gear m
