Direct replacement pinion for Tamiya F101/102

Sold as Tamiya 3515018, this 14T pinion is a direct fit option for F101/102 Group C and F1-style Tamiya chassis when shaft interface and retention match. It is specified by tooth count, so ensure the 14-tooth sizing lines up with your spur gear pitch and motor shaft requirements.

Compatibility comes down to shaft diameter and whether the motor uses a set screw or clamp; always cross-reference part number 3515018 with your chassis parts list. For installation, removing the motor to set correct mesh and endplay is recommended to avoid gear misalignment.

As a general rule, fewer teeth on the pinion shift the ratio toward torque and acceleration, while more teeth increase theoretical top speed. Test any changes progressively to avoid stressing the drivetrain.

Confirm your motor shaft diameter and fastening style, and verify part number 3515018 for assured fitment with Tamiya F101/102 or F1 chassis variations.

Will this pinion work on other Tamiya models?

It may fit other models that share the same shaft diameter and set screw type, but always confirm part 3515018 and measure the shaft before assuming interchangeability.

What shaft measurements matter for compatibility?

Measure the motor shaft diameter and note whether the pinion seats against a shoulder or is secured to motor flats. These details determine if the 14T pinion will seat and clamp correctly.

Can I use a different set screw when fitting this pinion?

You can use a compatible set screw if it matches shaft geometry and thread size; ensure it does not protrude into the bore and that it tightens securely without damaging the shaft.

Is special tooling required for installation?

Basic hand tools are usually sufficient: hex keys for set screws, a small press or vise for gentle seating if needed, and a feeler gauge to set mesh. No specialised factory tools are normally required.
