Service & Installation Instructions

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)

Figure 3

After verifying that proper voltage and current are sup­plied to the clutch as outlined by the operator’s manu­al, proceed with procedure outlined below.

Do not remove brake pole from

with clutch off and brake on and need to
continue to match after shim is removed to
ensure proper brake torque.
