Precision replacement pinion for motor pinion area

This replacement motor pinion is produced for TRAXXAS UNLIMITED DESERT RACER style motor assemblies and seats in the motor pinion area. Machined and heat treated to hardened steel #45 specification, the 28T gear is intended to provide improved wear resistance for repeated runs and setup adjustments.

Package contents are provided below following manufacturer notation:

  • Motor Gear - 1pcs
  • 4x4 Set Screw - 1pcs

The gear supplied is 28T, compared to the referenced 127T original; correct installation requires aligning the pinion to the corresponding positioning hole on the motor mount, setting an appropriate mesh clearance, and securing the 4x4 set screw to maintain precise motor alignment and consistent performance.

What are the material and treatment details?

The pinion is manufactured from steel and finished to a hardened #45 level to increase surface durability under pinion load cycles common to UDR applications.

How should I verify alignment during installation?

Align the pinion with the motor mount positioning hole, rotate the assembly to inspect tooth engagement, set minimal acceptable backlash, then tighten the set screw and confirm no axial play.

Are replacement set screws standard?

A 4x4 set screw is included with the gear; use it to secure the pinion and consider thread locker in high-vibration applications.
