TT01 42-Pitch 61-Tooth Delrin Spur Gear DTT4261T for TAMIYA by GPM  [DTT4261T]

TT01 Delrin spur gear replacement

Model DTT4261T is a Delrin 42-pitch 61-tooth spur engineered as an aftermarket spare for TAMIYA TT01 transmissions, suitable for replacing worn spurs or changing drive ratio for different track demands.

Ensure your TT01 uses 42-pitch gearing before fitting and check pinion mesh and clearance carefully. Proper shimming and examination of the spur hub and bearings during installation will help avoid premature wear.

Fitting a 61T spur reduces gearing for stronger acceleration at the expense of top speed; builders often prefer Delrin to reduce gear noise and smooth engagement when compared with harder materials.
