Workshop Tip - 17mm Thrust Washers

Hobbyists who keep their models in top order will find the Tamiya 50645 - 17mm Thrust Washer Set for RC Cars SP-645 a straightforward addition to their spares box. The four washers are aimed at reducing friction where axial loads occur, helping gears and shafts to run truer for longer.

Typical Applications

These washers slot into axial bearing locations to limit play and reduce abrasive wear on mating surfaces. They are especially handy during setup work, where fine spacing changes can improve steering feel and drivetrain efficiency.

Compatibility Notes

The 17mm sizing makes these washers compatible with many Tamiya models and other cars that use similar thrust clearances. Measure your existing spacing before fitting to ensure correct placement and function.

Verify that the required thrust clearance is 17mm and confirm shaft diameter and gearbox spacing. A quick measure with calipers will tell you if the washers will seat correctly.
They affect axial positioning rather than spur pinion engagement, but any change in shaft position should be checked to ensure gear mesh remains correct after fitting.
Yes, they are commonly used in race setups to control end float and maintain consistent handling during repeated runs. Regular inspection is recommended after heavy use.
