KH AFB C

KH-AFB Crank arm

Including Retaining Ring

CAUTION:

The retaining clip supplied with the clamp is

not

used to mount the KH-

AFB crank arm.

The KH-AFB crank arm is used in non-direct coupled mounting applications. The KH-
A

AFB may also be used to simultaneously direct couple to a damper shaft and provide
an additional crank arm connection to a second damper.
