Tamiya TB04 66T Delrin 48P Spur Gear DTB4066T by GPM  [DTB4066T]

TB04 Delrin 66T Spur Replacement

This single-piece Delrin spur is an aftermarket spare tailored for the Tamiya TB04 platform, featuring a 48 pitch, 66-tooth design for the TB-04 spur position. Supplied as 1 pcs, it is intended to replace worn large spur gears or to give hobbyists a reliable plastic upgrade option.

Acetal Delrin offers a low friction surface and good dimensional control during normal RC operation, supporting consistent gear mesh and predictable wear patterns on 48 pitch setups. Verify pitch and tooth count when matching with your pinion to maintain correct engagement and avoid premature wear.

Fitment advice: install as the TB-04 spur gear replacement, check alignment and mesh carefully, assess gearbox bearings and pinion for any signs of wear, and rotate the drivetrain by hand to confirm free movement before final assembly. This part is intended for model use only.
