Item Name:
Covington Parts - Tumbler Drive Pulley 1/21 HP
SKU:
COVPUL300-1/21
Description:
The Tumbler Drive Pulley 1/21 hp is a replacement drive pulley used in Covington rolling tumbler systems that run a 1/21 horsepower motor. This pulley is a machined metal component designed to mount to the tumbler drive shaft and transmit power from the motor through a belt drive. In a belt-driven tumbler, the pulley ratio helps set the roller speed, which directly affects tumbling action and overall grinding and polishing efficiency. This part is used when a pulley is worn, damaged, or being replaced during routine maintenance to keep the tumbler running smoothly and at the intended operating speed.
How it is used:
- Disconnect power to the tumbler before servicing.
- Remove the belt guard and relieve belt tension to access the drive components.
- Remove the worn pulley from the drive shaft and install the replacement pulley in the same position and orientation.
- Reinstall and tension the belt so it tracks correctly, then replace the belt guard before operation.
- Use the restored belt drive to maintain consistent roller speed for steady grinding and polishing runs.
