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

This is a replacement spur gear pack intended for the Tamiya TT-01 TYPE-E platform, supplied under model TT01-28. The kit includes three tooth-count variants - 55T, 58T and 61T - allowing systematic adjustment of overall gear ratio without modifying motor placement or gearbox mounting points.

Tuning strategy: use the 55T gear to increase effective drive ratio for faster acceleration, the 58T for a compromise setup, and the 61T where higher top speed and improved low rpm torque smoothness are required. Keep the existing pinion and motor to evaluate the incremental effect of each spur size on motor load and rpm range.

Installation and checks: replace the TT-01 TYPE-E large spur within the gearbox assembly. On assembly, ensure correct backlash to the motor pinion, confirm concentric seating of the spur on the shaft, and verify bearing engagement without lateral play. Perform a controlled low-speed rotation test and monitor motor current and drivetrain noise prior to full-power runs.
