Precision Replacement Pinion for Lunch Box Vehicles

For builders seeking dependable drivetrain behaviour, the Tamiya 3505015 pinion gear is a direct-fit option for Lunch Box models 58063, 58347, 58546, and 58575. It supports smooth transfer of power and helps maintain correct gear mesh under load. The part is appropriate for routine servicing or modest upgrades.

Designed for Accurate Tooth Engagement

The Tamiya 3505015 is produced to deliver repeatable tooth geometry, which reduces uneven wear and helps spur gears stay aligned. That accuracy makes it a sensible choice when replacing a worn pinion or restoring original drivetrain performance.

Good for Maintenance and Modest Tuning

This pinion works well when replacing damaged components or adjusting gearing for a different motor or driving style. With careful mesh setup, the Tamiya 3505015 helps maintain efficient power delivery and prolongs the life of surrounding drivetrain parts.

Measure your motor shaft diameter and compare it to the replacement pinion bore. If in doubt, remove the old pinion to verify fit before final installation.
Check for smooth rotation by hand, confirm the set screw is secure, and run at low throttle to listen for unusual noise indicating poor mesh or misalignment.
Yes, provided the spur gear has compatible tooth form and the mesh is adjusted correctly; mismatched profiles can increase wear and noise.
Yes, inspect the mesh and set screw after a short test run, then again after a few sessions to ensure nothing has loosened and wear is even.
