Description:
The Tumbler Drive Pulley 250 is a replacement drive pulley used in Covington rolling tumbler systems configured for the 250 series drive setup. This pulley is a machined metal component designed to mount to the tumbler drive shaft and transfer power through a belt drive to the roller system. In a belt-driven tumbler, the pulley size and ratio help determine roller speed, which affects how consistently your load turns during grinding and polishing. This part is typically used when the original pulley is worn, damaged, or being replaced during maintenance to restore proper belt tracking and dependable tumbler operation.
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 existing pulley from the drive shaft and install the replacement pulley in the same position.
- Reinstall and tension the belt so it runs true, then replace the belt guard before operation.
- Run the tumbler briefly to confirm smooth rotation and consistent belt alignment.
