CONVERTING HUBS FROM GREASE TO OIL
Oil filled bearings are better lubricated and have proven to be
necessary when running in hot conditions to give long life. Should
you wish to convert to oil filled:-
1. Remove hub as described in Hub Removal, if original bearings
are to be re-used ensure they are refitted in the original hubs.
2. Clean out the grease from the hub cavity and wash out both
bearings with a suitable cleaner. If the bearings are dried with the
use of an air jet avoid rotating the bearings at high speed.
3. Refit inner bearing into hub and fit a new unitized oil seal.
4. Refit hub, refit outer bearing and adjust bearings as described
in Hub Refitting.
5. Fit new oil filled hub cap and gasket.
