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

TB-04 Delrin Spur Gear Unit

This Delrin spur gear is supplied as a single aftermarket replacement for the Tamiya TB04 chassis, with a 48 pitch 66-tooth profile suited to the TB-04 large spur location. Supplied as 1 pcs, it is intended for replacing damaged or worn spur gears and for modders seeking a durable plastic alternative to factory parts.

Delrin, an acetal polymer, balances low friction with stable dimensions under usual RC loads and helps preserve consistent tooth contact on 48 pitch systems. Always confirm the gear pitch and tooth count against your motor pinion to ensure proper mesh and to avoid damage.

Fitting notes: install as an RC-scale replacement on the TB-04, set axial alignment and backlash correctly, inspect gearbox bearings and pinion for wear before reuse, and check for smooth rotation by hand prior to final assembly. This part is intended for model use only.
