Belt for Thumler's T2 tumbler

Thumler's T2 Belt

Only $5.99
Replacing the belt on a Thumler's T2 tumbler is an easy job that can be done without tools. If your T2 tumbler has the belt guard, swivel it out of the way. Then lift up the drive shaft and remove the old belt. Slip the new one over the pulley, push the drive shaft back down into place, and roll the belt over the motor pulley.
Thumler's tumbler bearings

T2 Tumbler Bearings

Four for $7.99
Thumler's T2 bearings are made of durable polyethylene. Bearings are simple to replace. Remove the retainer clip, slide the old bearing off, put the new one on, and replace the retainer clip. We suggest purchasing some extra retainer clips just in case one gets damaged.
