For 48-Pitch Motors: 19T Pinion Gear - Yokomo YOKPG4819  [YOKPG4819]

48-Pitch 19T Pinion Gear Details

The Yokomo YOKPG4819 is an RC-scale pinion gear engineered for 48-pitch drivetrains. The 19-tooth profile allows builders to adjust overall gear ratio in small, predictable increments when matched with a 48-pitch spur gear.

In operation, this part alters the balance between acceleration and top speed without changing motor or ESC settings. Proper fitment requires a motor shaft and a spur gear that follow the 48-pitch standard so tooth mesh and backlash can be set correctly.

Installation notes: slide the pinion onto the motor shaft, align the tooth mesh with the spur gear, and verify smooth rotation across full suspension travel or drivetrain articulation. Recheck mesh under load and after a few runs, retighten mounting hardware as needed and inspect the teeth for wear.

Maintenance tips: keep mating gears free of grit, inspect for chipped or worn teeth before each session, and replace the pinion if wear alters mesh. This component is intended for 1/10 electric RC cars and should be used with compatible 48-pitch parts.
