Thumler's Model T Belt
Replacing the belt on a Thumler's Model T tumbler is an easy job that can be done without tools. Lift the drive shaft off of the frame, slip the belt over the pulley, replace the drive shaft and roll the belt over the motor pulley.
Model T Tumbler Bearings
Thumler's Model T 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 you damage some while removing or replacing them.
Stop Squeaky Bearings
We oil our Thumler's Tumblers every 30 days (or after each batch of rocks) with 3-IN-ONE Multi-Purpose Oil or SAE20 motor oil. Only one drop on each bearing. See our article for photos and detailed instructions.
Needle-Tip Oil Bottle
Have your own SAE20 motor oil or general purpose oil? Use one of these needle-tip bottles to accurately dispense it on tumbler bearings and motors. Keep your tumbler running smooth and quiet.
Thumler's Model T Barrel Guides
Thumler's Model T 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 might wear down and need to be replaced. We offer a set of two rollers for the A-R1, A-R6 and Model T 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, A-R6 and Model T tumblers, while a set of three rollers is needed for the A-R2 and A-R12 tumblers.

Thumler's Model T Motor Mounting Nuts
Two keps nuts (nuts with attached, free spinning, star-shaped lock washers) are used to keep the motor in place. They screw onto the two motor-mounting bolts where they extend through the motor housing, one on each side of the opening where the motor's drive shaft protrudes. A 9mm wrench is needed to install.
