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

This spare spur gear set fits the Tamiya TT-01 TYPE-E and is listed as model TT01-28. The pack contains three tooth-count choices - 55T, 58T and 61T - enabling ratio adjustments without moving the motor or changing the chassis layout.

Tuning guidance: swapping the supplied tooth counts is an easy method to tune acceleration against top speed for different track types. Smaller tooth counts increase drive ratio for snappier acceleration, while larger tooth counts favour top speed and smoother low rpm torque. Use these gears to test performance changes while retaining your current pinion and motor setup on the TT-01 TYPE-E platform.

Installation advice: replace the existing large spur within the TT-01 TYPE-E gearbox assembly. When fitting, set the gear mesh to the motor pinion, ensure the spur runs concentric on the shaft and that bearings engage correctly with no side play. Perform a slow rotation check through the drivetrain before final running.
