TRAXXAS TRX4 CNC-Grade 14T Pinion TRX4014T by GPM  [TRX4014T]

14T Hardened Steel Pinion for Motor Drive

Aftermarket 14T pinion set engineered for TRAXXAS TRX4 platform use, supplied as two gears plus a 3x3 securing screw. The pinion mounts directly to the motor shaft and transmits torque into the spur and drivetrain, providing a durable replacement option for scale crawling rigs.

Technical notes follow the provided data: material hardened steel #45, tooth count 14T, centre bore 3.175mm, tooth distance 0.8mm and pitch 32. The included 3x3 screw shaft secures the pinion to the motor. Confirm compatibility with your spur gear tooth form and motor shaft size prior to installation.

Installation guidance for workshop fitting: verify shaft diameter, set correct backlash with the spur gear to avoid premature wear, and tighten the securing screw to appropriate torque for your motor shaft material to prevent slippage. Selecting a different tooth count will adjust the final drive ratio and should be chosen based on terrain and motor characteristics.
