How to Install the Rotation
Bearing and Worm Drive
The rotation bearing is a structural component. It
attaches the drive 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 correctly positioned to provide
the correct gear lash between the worm gear and
the ring gear. The outside bearing race is bolted to
the drive 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
drive 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 drive
chassis. Use appropriate lifting techniques.
2 Locate the “G” mark stamped on the outside
bearing race. Align the mark with the rotation
stop block on the chassis.
