1. DuraCirc models 52 to 74 only: Allow
bearings to cool to ambient temperature.
Failure to do so will result in incorrectly
set bearings.
2. Fit the tabbed lock washer (56) on the
shaft with the tabs angled away from the
bearing.
3. Locate and tighten the bearing nut (57),
whilst at the same time rotating the
bearings (54) and spacer (55). The
bearings are correctly adjusted when the
spacer can only be moved with a light tap
of a mallet.
4. Once in place bend one of the tabs of the
tabbed lock washer (56) in to the nearest
cut out on the bearing nut (57). If no tab is
aligned with the cut out on the bearing nut
tighten the bearing nut slightly until
aligned with a tab.

compound to the bearing diameters.
