Care of Arbors and Adapters
Although the adapters, arbors, and the spindle are
made of top grade steel and are turned, hardened,
and precision ground to close tolerances, great care
should be taken in their use, handling, and storage.
Even the smallest nick, scratch, or loose chip can
cause incorrect rotor or drum alignment and the
result will be inaccurate machining.
Always inspect the faces and the seating tapers of each
adapter. Wipe each adapter clean before and after use. Carefully
correct any flaw with a fine stone. If the damage cannot be cor-
rected, replace the part.
Handle and store arbors and adapters with great care. Keep
them clean and oiled with light machine oil. DO NOT dump
them together in a box to collect nicks and dirt. DO NOT use the
adapters for any other purpose than they are intended.
Remove all adapters from the arbor after machining a drum or
rotor and wipe them clean - especially the inboard adapter.
When a finished drum or rotor is removed from the arbor, the
inboard adapter may move slightly away from the face of the
arbor and allow chips or dust to fall into the opening. If these
chips are not cleaned from between the arbor face and the
adapter, they may adversely affect the machining of the next
brake part.
