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.
1. Drill a pilot hole in the face of the shaft seal less than the depth limit specified above.
Be sure the drill does not come in contact with the shaft seal bore.
2. Thread the screw or bolt into the pilot hole.
3. Lift the shaft seal from the motor by grasping the screw head and slightly rotating the
seal while pulling.
4. Inspect and clean the shaft and sealing surfaces as necessary.
Replace the Shaft Seal
No tools are required to install the replacement shaft seal.
1. Apply the provided grease to the inner ring of the shaft seal and motor shaft.
2. Center the shaft seal on the mounting surface of the motor with the seal oriented in the
same manner as the removed seal.
3. Press the shaft seal into the seal recess by applying pressure with your fingertips in a
circular fashion to slowly seat the shaft seal in place.
The surface of the seal must be 0.6 mm (0.02 in.) below the pilot surface.
4. Verify that the outer and inner circumference of the shaft seal is fully seated into
position.
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 This shaft seal requires a lubricant to reduce wear. The lubricant is supplied in the kit.
TIP To verify that the shaft seal is fully seated into position, run your fingertip around the
seal-to-motor joint and feel for irregularities in the shaft seal, or an uneven alignment where
the shaft seal contacts the motor.
