Check the part before you buy

Start with the label on your machine and the original part number. The same-looking lid, belt or drum can differ by model, and a stated weight alone does not establish fit.

KomeStone K1 / K1 Pro
2.5 lb replacement barrel or motor

The manufacturer lists one replacement barrel for both models, but its K1 motor is K1-only. Use the exact machine label when shopping for the drive part.

Part reference
Raytech TV-5
23005R bowl and cover

Match the eight-inch bowl to the TV-5. The center fastening parts have separate references, so check the contents if you need the rubber nuts as well.

Thumler A-R6 / A-R12
Lid and retainer

The A-R6 uses a nine-pound barrel with a retaining ring. The A-R12 uses a different lid and a metal clamp. Match both the vessel and the closure before buying.

Thumler MP-1 / Model T versus A-R2
Drive belt

Compare the original THU400 thin belt with the separate THU401 thick belt. Use the model from the manufacturer list before selecting a replacement profile.

Part reference
MJR rotary tumblers
Polymer drum

Compare the original drum dimensions with the maker’s size chart and check the base width. The nominal capacity helps identify a variant, but the roller spacing and supported working load determine suitability.
