Tamiya 3515018 14 Tooth Pinion for F101/102 and F1 Chassis  [3515018]

14T Pinion: maintenance and longevity

Designated Tamiya 3515018, this 14-tooth pinion is suitable for F101/102 Group C and F1-style Tamiya chassis as a replacement or service item. Because the specification is the tooth count, confirm the 14T measurement to ensure correct meshing with your spur gear.

Proper fit requires matching the motor shaft diameter and the retention method; check part number 3515018 against your build notes before fitting. Removing the motor to set correct mesh and axial play will extend gear life and help avoid premature wear to teeth and bearings.

From a longevity standpoint, correct mesh and gradual break-in under light loads will reduce stress. Adjust ratios in small steps to avoid sudden increases in current draw that can accelerate wear.

Always verify shaft diameter and set screw type, and confirm part number 3515018 to ensure correct fit and long-term reliability with your Tamiya F101/102 or F1 chassis.
