How to Install the Rotation
Bearing and Worm Drive
The rotation bearing is a structural component. It
attaches the chassis to the turntable. The
turntable is bolted to the inner race, with the worm
gear housing sandwiched in-between. This
housing has to be exactly positioned to provide the
correct gear lash between the worm gear and the
ring gear. The outside bearing race is bolted to the
chassis from the underside.
This procedure requires specific
repair skills, lifting equipment and
a suitable workshop. Attempting
this procedure without these skills
and tools may result in death or
serious injury and significant
component damage. Dealer
service is required.
If a repair requires that the
turntable be removed from the
chassis, installing a new rotation
bearing is recommended.
Consider the service life of the
rotation bearing before installing a
used bearing.
1 Position the rotation bearing on the chassis.
2 Locate the "red" mark on the outside bearing
race. Align the mark with the rotation stop
block on the chassis.
