NOTICE:
Failur
e to ensure a correct preload on the bearing may shorten the service life of the
pump.
Fit and use the preload tool. While performing this check, record he posion of the test
indicator when a change in preload transion occurs.
If the test indicator falls within the pass limit, no further acon is required.
If the test indicator falls above or below the pass limit when a change in preload
transion occurs, adjust the bearing preload force. Using the preload tool body, rotate
the magnec bearing adjuster nut (viewed from top) clockwise if the test indicator is
above the pass limit, or counter-clockwise if the test indicator is below the pass limit.
We recommend that you monitor the preload force using the preload tool test plunger
between 1 mm rotaonal increments. Connue this process unl the test indicator falls
within the pass limit.
If no preload is detected, slowly turn the preload tool body clockwise unl preload is
established. When the preload has been veried, measure the preload force by
following the corresponding instrucons above.
