This item is one drive belt to suit a Lortone 33B or 45C rock tumbler.
After a period of use, the drive belt may stretch and cause the drive shaft to stop rotating - if belt tension cannot be adjusted sufficiently by the drive motor screws, you will need to replace the drive belt. Will NOT fit the 3A tumbler.
Part K on the parts list - item 210-002.
Note from Lortone: To ensure proper motor life and performance, it is important that the drive belt be kept as loose as possible without slipping on the pulleys. Excessive tension can cause motor bearing failure. When oiling drive bearings, take care not to get oil on the drive belt as this may cause damage to the belt.
For information on how to change or adjust the belt, please see our YouTube video here.
