Required Tools
Use these tools to install a shaft seal:
•
Rubber/wooden mallet, or a metal hammer and wooden work piece
•
Socket, pipe, or tubing (various sizes)
•
Abrasive cloth (to remove any nicks or burrs from the motor shaft)
Install a Shaft Seal
Follow these steps to install the shaft seal.
1. Verify that power is removed from the motor.
2. Remove the shaft key (if installed).
3. Remove the old shaft seal (if installed).
4. Remove any dirt or grease from the motor shaft and the area around the front end bell of
the motor near the bearing.
5. Use an abrasive cloth to remove any nicks or burrs from the motor shaft.
6. Cover the sharp edges of the keyway with tape to protect the seal lip from damage.
7. Lubricate the inner and outer lip of the shaft seal with the lubricant in the kit.
8. Position the shaft seal so that the sealing lip faces outward on the shaft.
9. Slide the shaft seal onto the motor shaft.
10. See Shaft Seal Installation Clearances on page 3 for the correct installation clearance of
the shaft seal.
11. Use one of the Shaft Seal Installation Methods on page 4 to gently press the outer
diameter of the shaft seal into the motor.
ATTENTION: To avoid injury or damage to the equipment, remove power from the motor before installing the
shaft seal.
IMPORTANT Shaft seals must be lubricated. Lubricant is supplied with the shaft seal kits.
IMPORTANT Verify that the shaft seal is installed to the correct installation clearance.
If the shaft seal is installed too deep, it can be subject to excessive wear and require frequent
replacement.
If the shaft seal is installed too shallow, it can reduce the effectiveness of the protective seal.
