Tamiya F101/102 Group C and F1 Chassis 14T Pinion Gear - 3515018  [3515018]

14-tooth Pinion for F1-style Tamiya Chassis

This 14T pinion is listed as Tamiya 3515018 and is intended as a drop-in motor pinion for F101/102 Group C and F1-style Tamiya chassis. It is specified by tooth count, so confirm the 14-tooth dimension when matching to your spur gear rather than relying on material descriptions.

Fit depends on motor shaft diameter and the retention method used; always check part number 3515018 against your chassis parts list before fitting. Installation is typically done by removing the motor to set mesh and axial play, then securing the pinion with the existing set screw or clamp system.

When tuning, a 14-tooth pinion shifts the drive ratio: fewer teeth deliver more low-end bite and torque at the expense of theoretical top speed. Make changes incrementally and test on-track to find the best balance for your setup.

Confirm shaft diameter and set screw style, and verify part number 3515018 to ensure correct compatibility with your Tamiya F101/102 or F1 chassis.
