Warner Electric Re-gap Adjustment Procedure - Manual (Page 2)

When to remove shim:
When a clutch has worn to the extent that the
existing air-gap is too large to allow for complete clutch
engagement (clutch may engage easily when cold but
has problems engaging when hot), the brake shim can
be removed to restore air gap and allow the clutch to
continue to function. (With engine off, key removed and
clutch disengaged)
After verifying that proper voltage and current are sup-
plied to the clutch as outlined by the operator’s manu-
al, proceed with procedure outlined below.
Component Identification Reference
CMS250 pictured, same procedure applies to CMS200
Procedure:
Consult the operator’s manual for
all related procedures & safety practices.
Using a pneumatic line, blow out any debris from under
the brake pole and around the aluminum spacers.
1. Loosen both brake mounting bolts 1/2 to 1
full turn as shown below. (Figure 3)
Do not remove brake pole from
field shell/armature - brake pole tracks match
with clutch off and brake on and need to
continue to match after shim is removed to
ensure proper brake torque.
2. Using needle nose pliers, or by hand, take hold
of the tab and remove shim (do not discard shim
until proper clutch function has been confirmed).
