Thumler's Model A-R1 Belt
Replacing a worn out A-R1 belt is one of the easiest fixes on the tumbler. No tools are required for the fix.
Model A-R1 Tumbler Bearings
Thumler's A-R1 bearings are made of durable polyethylene. Bearings are simple to replace. Remove the retainer ring, slide the old bearing off, put the new one on and replace the retaining ring. We suggest purchasing some extra retainer rings just in case one gets damaged.
Thumler's A-R1 Barrel Guidess
Thumler's A-R1 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.
