Shaft Seal Kits
Remove the Shaft Seal
The shaft seal can be safely removed by partially inserting an appropriately sized screw or bolt
into the face of the shaft seal. The head of the screw or bolt provides a convenient point to grasp
and remove the shaft seal.
Before installing the screw, create a pilot hole appropriate for the screw being used. Use masking
tape or a depth sleeve to establish a drilling depth limit of 4 mm (0.16 in.) from the tip of the drill
bit.
Follow these steps to remove the shaft seal.
1. Remove power to the motor before removing the shaft seal.
2. Drill a pilot hole in the face of the shaft seal less than the depth limit specified above.
Make sure the drill does not come in contact with the shaft seal bore.
3. Thread your screw or bolt into the pilot hole.
4. Lift the shaft seal from the motor by grasping the screw head and slightly rotating the
seal while pulling.
5. Inspect and clean the shaft and sealing surfaces as necessary.
Use an abrasive cloth to remove any nicks or burrs from the motor shaft.
ATTENTION:
To avoid injury or damage to the equipment, remove power from the motor before
removing the shaft seal.
ATTENTION:
Do not drill into the shaft seal deeper than 4 mm (0.16 in.).
Drilling and inserting a screw completely through the shaft seal can damage the motor bearings,
and require factory service to repair the motor.
IMPORTANT
Cover the sharp edges of the keyway with tape to protect the shaft seal lip from
damage.
