GPM SBJ016T Steel Pinion Gear 16T for Baja 5b/5b Ss/5T  [SBJ016T]

16T steel pinion for Baja

This steel pinion is an RC-scale replacement part intended for motor-to-spur engagement on Baja 5b/5b Ss/5T platforms. It is offered as a single-piece steel pinion, and the original listing specifies it must be paired with the GPM SBJ058T spur gear to achieve correct gear interaction.

In practical terms the pinion serves the drivetrain role of transferring torque from the motor to the spur gear while resisting wear better than softer materials. When fitting, position the pinion on the motor shaft according to your motor’s fastening method, confirm proper gear mesh with the matching spur, and secure the pinion so it does not shift under load. Regular inspection for wear and correct backlash preserves drivetrain life and reduces noise.

The part is supplied as one steel pinion intended as a direct replacement where the matching spur gear specification is met; do not mix with unmatched spur gears to avoid improper meshing.

Use this steel pinion when replacing a worn motor pinion on the listed Baja platforms and when running the specified GPM SBJ058T spur gear to maintain correct drivetrain geometry.
