Heavy-Duty Pinions for Consistent Drive

The Tamiya 53103 Steel Pinion Gear Set is made for 1/10 on-road RC cars and supplies a 24T and a 25T pinion manufactured from robust steel to withstand repeated stress. Precisely cut teeth ensure smooth engagement with compatible spur gears, helping to maintain predictable power delivery during spirited driving.

What Sets the Tamiya 53103 Apart

  • Material: Robust steel construction for extended durability
  • Teeth Count: Includes one 24T and one 25T pinion
  • Compatibility: Intended for Tamiya 1/10 on-road gearboxes
  • Efficiency: 0.4 module specification for dependable engagement

Installation Notes and Recommended Pairings

This pinion set works well with the Tamiya Spur Gear (53104) and the Aluminum Motor Mount (53106) for a coherent drivetrain upgrade. The packaging provides grub screws and a hex key for fitting; follow the printed guidance to set correct mesh and secure the pinion firmly.

Can I switch between 24T and 25T to change gearing?

Yes, swapping between the included 24T and 25T alters final drive ratio; choose the tooth count that best matches your track or handling preference.

Do I need special tools to fit these pinions?

No specialist tools are required beyond the supplied hex wrench, but a small driver and a marker to note set screw position can help with repeatable installation.

How do I check for wear on steel pinions?

Inspect teeth for rounding or gouging and listen for increased gear noise; replace pinions if engagement becomes rough or if tooth profiles degrade.

Will these pinions fit non-Tamiya motor mounts?

They may fit other setups that use the same shaft diameter and 0.4 module gearing, but confirm bore and clearance before committing to a permanent fit.
