) You may have different version of the Hiller Arm. It works the same; please see the figure for installation
Note: Some Center Hubs are designed for one O-ring each side. If this is your case, use
one O-ring each side. The beveled edge of the Thrust Bearing Spacer (No. 11) should
be face away from the Center Hub. The flanges of the bearings of the Hiller Arms should
face outside. Usually the Thrust Bearing has three parts: two race washers and caged
ball bearings. The caged ball bearings will be between two race washers. In some cases,
you may get different version of the Thrust Bearing: one race washer, one flat washer,
and caged ball bearings in your kit. That is fine; it still works the same. In this case, you
need to install the flat washer first (next to Thrust Bearing Spacer-No. 11), then the
caged ball bearings, the race washer goes last. Remember to apply grease for bearings.
