3Racing Tamiya TT-01 TYPE-E Spur Gear 55/58/61T - TT01-28 - RC Spare Part  [TT01-28]

This replacement spur gear set is made for the Tamiya TT-01 TYPE-E and is supplied as model TT01-28. It includes three tooth counts - 55T, 58T and 61T - so you can alter overall gear ratio without changing motor position or chassis layout.

Tuning purpose: swapping between the supplied 55T, 58T and 61T gears gives a simple way to balance acceleration and top speed for different surfaces and driving styles. Lower tooth counts deliver stronger acceleration, while higher tooth counts favour top speed and smoother low rpm behaviour. These sizes let you keep the same pinion and motor while testing ratio changes on your TT-01 TYPE-E.

Fitting notes: this part replaces the large spur inside the TT-01 TYPE-E gearbox. When installing, set correct gear mesh with the motor pinion, ensure the spur runs true on the shaft and that bearings are engaged without lateral play. Complete a low-speed drivetrain check to confirm smooth rotation before full-speed runs.
