Thumler's Model A-R6 Belt
Replacing a worn out A-R6 belt is one of the easiest fixes on the tumbler. No tools are required for the fix. It is a good idea to have an extra belt lying around in case a belt breaks in the middle of tumbling a batch of rough.
A-R6 Tumbler Bearings
Thumler's A-R6 bearings are made of 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 you damage some while removing or replacing them.
Thumler's A-R6 Barrel Guides
Thumler's A-R6 tumbler barrel guides are made of nylon which makes them durable. You won't have to change these very often but when you do it is a simple job. Remove the retainer clip, remove the bearing and old guide, slide on a new guide and replace the bearing and retainer clip. Purchasing some extra retainer clips in case you damage one is a good idea.
Thumler's Shaft Retainer Clips
Retainer clips are used to hold the bearings on the end of the shafts and to hold the nylon rollers in the proper location on the idler shaft.
Thumler's Tumbler Nylon Roller
After years of use, the nylon rollers on the idler shaft may wear down and need to be replaced. We offer a set of two rollers for the A-R1 and A-R6 tumblers and a set of three rollers for the A-R2 and A-R12 tumblers.
Thumler's Rubber Roller
These rubber rollers for the drive shaft are what give the barrel traction and keep it turning to tumble the rocks inside. Replace worn rollers for optimum tumbling action. A set of two rubber rollers is needed for the A-R1 and A-R6 tumblers while a set of three rollers is needed for the A-R2 and A-R12 tumblers.

Thumler's A-R6 Idler Shaft

Thumler's A-R6 Barrel Lid
This is Thumler's A-R6 barrel. It is made out of plastic which means it will eventually wear through, so having an extra one on hand is a good idea.
Thumler's A-R6 Barrel Retaining Ring
This retaining ring is used to secure the lid on a Thumler's A-R6 Tumbler barrel. Note: This new retainer ring will appear much smaller than the one that you're replacing. That is because it hasn't been stretched out. It will fit the barrel, but it may be tough to stretch at first. In the video below, we share a tip on how to do it.
