TAMIYA TT02/TT02B 69T Delrin Spur Gear, 42 Pitch, Compatible Replacement - DTT2B069T by GPM  [DTT2B069T]

Aftermarket Delrin 69T Spur Gear Specifications

This Delrin spur gear is supplied as an aftermarket replacement for TAMIYA TT02 and TT02B vehicles. The unit is referenced as DTT2B069T and uses a 42 pitch tooth profile with 69 teeth to mesh with matching 42 pitch pinions.

Delrin gives a blend of low friction and dimensional reliability which supports consistent mesh under normal model loads. It is suitable for installation within the gearbox or at the motor mesh area and should be part of routine drivetrain inspections.

Fitting advice: set the initial pinion mesh before final assembly, confirm axial alignment and clearance for the 69T diameter, and avoid overtightening hardware to prevent Delrin distortion during installation.

Upgrade strategy: changing spur tooth count is a straightforward tuning option for the TT02 series; moving teeth counts up or down will shift the balance between acceleration and top speed, so plan swaps based on track and powerplant.
