Introduction
This sheet provides step by step installation
instructions for manufacturer furnished pulleys for
AT series clutch pulleys.
Failure to follow these
instructions may result in product damage,
equipment damage, and serious or fatal
injury to personnel.
Key and Snap Ring Mounting
1. Insert 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.
Note: For high cycle rate applications or
applications with potential pulley
misalignment, apply Loctite
® to the I.D. of
the pulley to eliminate the possibility of
keyway wear.
2. 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.
3. Install the furnished retaining ring with retaining
ring pliers. Ensure that the retaining ring is fully
seated around its periphery.
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.
Through Bolt Mounting
Note: This method is suitable for pulleys and
sheaves with adequate radial wall thickness
to accommodate through holes.
1. Drill holes through the pulley or sheave to
match the tapped holes on the hub shoulder
of the clutch.
2. Align the through holes in the sheave or
pulley with the tapped holes on the hub
shoulder and gently tap until it seats against
the shoulder.
Note: Installing the keyway and snap ring
are not necessary if the sheave or pulley is
held in place by the through bolt method.
3. Secure the pulley with capscrews, using
lockwashers or Loctite to assure thread
retention.
