Bearing preload check
The bearing preload tool checks that the bearing preload force is correctly set. If necessary,
the tool can be used to correct the bearing preload force if adjustment is required.
CAUTION:
Bearing preload checking is required to check and if necessary set the bearing preload
using the bearing preload tool. Failure to do so may shorten the service life of the
pump.
1. Fit and use the preload tool in accordance with pre-service Preload check on page 9.
While performing this check, the posion of the test indicator must be noted when
a change in preload transion occurs. Refer to Figure 13 on page 18.
2. If the test indicator falls within the pass limit, then no further acon is required.
Proceed to Service counter reset on page 18.
3. Adjustment of the bearing preload force will be required if the test indicator falls
above or below the pass limit when a change in preload transion occurs. Using the
preload tool body, rotate the magnec bearing adjuster nut (viewed from top)
clockwise if the test indicator is above the pass limit and an-clockwise if the test
indicator is below the pass limit.
It is advisable to monitor the preload force using the preload tool test plunger
between 1 mm rotaonal increments. Connue this process unl the test indicator
