Clutch Installation

1. Remove your AT Clutch from its shipping

carton and inspect it thoroughly to ensure
that it has arrived in good condition.

An accessory kit included with your clutch
contains a key, retaining ring, and coil wire
retainer. In addition, you may have ordered
the optional sheave or timing belt pulley and
field restraining strap.

Two methods for fastening pulleys and sheaves
are offered. For key mounting, follow the
instructions in 2. below; for through bolt
mounting, go to instruction 3.

Note: For high cycle rate applications
with potential pulley misalignment,
apply Loctite to the I.D. of the pulley to
eliminate the possibility of keyway wear.

b. Gently tap the sheave or pulley until it

seats against the hub shoulder.

Note: Do not force the pulley or sheave
onto the hub if it will not go. Check
alignment to assure it is going on evenly.
Check for burrs or ridges on the shaft
and remove any which may be present
with a file.

c. Install the furnished retaining ring with

retaining ring pliers. Ensure that the
retaining ring is fully seated around its
periphery.

2. Key and Snap Ring Mounting

a. Install the factory ordered sheave or pulley

by first inserting the factory furnished key
into its keyway in the clutch hub. Position
the sheave or pulley so it will fit onto the
hub, aligning the keyway with the key. Be
sure to keep the tapped pulley removal
holes accessible.

When installing this or other
retaining rings, be sure to hold the ring with
one hand so it will not spring away should the
pliers lose their grip on the ring. Always wear
safety glasses when installing or removing
retaining rings.
