For Brake Lathes
Operating and Service Instructions
No. 909232GP

The double taper cone adapters are made of
premium grade alloy steel. They have been
turned, hardened, and ground to extremely
close tolerances in concentricity and end
squareness to assure the accurate location of
hubbed drums and rotors for precision resurfac-
ing.
The two tapers on each adapter are radiused,
not just coned. This results in a greater circular
bearing surface than is possible with a straight
taper cone and less chance of distortion to the
hub bearing race.
The diameter range of the two tapers on each
adapter also overlap in the sets to provide an
overall diameter range of 1.319" to 3.560". The
adapter sets thus match the hubbed bearing
surface of passenger cars, trucks, and RVs.
Instructions
After selecting the correct adapters to fit the
hubbed bearing seats, make sure the adapters
and the arbor are clean of all chips and dirt. The
proper mounting sequence is illustrated: Inner
adapter, hubbed drum or rotor, outer adapter,
any spacers necessary to fill out the arbor shaft,
the self-aligning spacer and the arbor nut.
