Baja 5b/5b Ss/5T 16T Steel Pinion SBJ016T Motor Replacement by GPM  [SBJ016T]

16T steel motor pinion for Baja use

This steel 16T pinion is offered as a straightforward replacement part for Baja 5b/5b Ss/5T models. It is a single-piece steel pinion and should be matched with the SBJ058T spur gear to secure correct tooth contact and gearbox alignment.

The pinion's role is to transfer drive from the motor to the spur while resisting wear better than softer alternatives. Mount the pinion to the motor shaft following the motor maker's fastening method, establish correct gear mesh with the matching spur, and clamp the pinion to prevent movement under load. Regular checks of backlash and tooth condition will help reduce noise and extend service life.

Sold as one steel pinion for replacement use when the matching spur specification is met; avoid mixing with unmatched spur gears to prevent improper meshing.

Choose this 16T steel pinion when replacing a worn motor pinion on the listed Baja platforms and when using the SBJ058T spur to maintain correct drivetrain geometry.
