Yokomo YOKPG4818 18T 48-Pitch Hardened Pinion  [YOKPG4818]

Hardened 18T Pinion for 48-Pitch Systems

This component is a hard precision pinion built for 48-pitch RC drivetrains. With 18 teeth it serves as a mid-range option to tweak final drive without changing the spur, enabling balanced trade-offs between acceleration and top speed in 48-pitch configurations.

Confirm compatibility by ensuring your motor uses a 48-pitch shaft and that the spur gear matches; inspect shaft diameter and set screw location before fitting. Proper mesh and minimal backlash are critical to avoid premature wear of the pinion and spur teeth.

Adjust pinion size in single-tooth increments and run tests between swaps to evaluate performance. Secure the pinion with the correct torque or a thread-locking product where suitable, and revisit mesh settings after any break-in period or drivetrain work.
