TRAXXAS MAXX 18T Hardened Steel Motor Pinion TXMS018TS by GPM  [TXMS018TS]

Precision 18T motor pinion for TRAXXAS MAXX

This #45 hardened steel motor gear is engineered as a direct replacement to interface with the motor output on TRAXXAS MAXX monster truck platforms. It is intended to transmit rotational torque to the drivetrain while maintaining accurate mesh between the motor pinion and mating gear under load conditions.

Installation procedure: position the pinion square to the motor shaft, set the recommended mesh clearance, and torque the set screw to secure axial position. The hardened steel material is specified to increase wear resistance compared with softer alloys, supporting consistent engagement during tuning cycles and sustained operation.

Service recommendations: inspect mating surfaces for contamination, ensure uniform tooth contact across the face width, and perform a controlled low-speed run to validate free rotation and absence of binding prior to full-power testing.
