Precision Pinion for 48-Pitch Gears

The Yokomo PG-4837A Precision Hard Coated Aluminium Pinion Gear is produced to match 48-pitch spur gears and provide consistent 37-tooth engagement. It helps reduce vibration and keeps gear alignment steady in tuned rigs.

Why Use An Aluminium Pinion?

Aluminium pinions cut rotating mass which helps rev response and handling. The hard coating gives improved surface hardness so the teeth last longer under load than untreated aluminium.

Installation Advice for Best Mesh

Install the Yokomo PG-4837A by confirming spur pitch and checking axial runout before locking the pinion. Small mesh adjustments with shims will prevent premature tooth wear and improve drivetrain efficiency.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Can I swap this into any 48-pitch car?

Yes, provided the car uses a 48-pitch spur and the motor pinion diameter and shaft fit the pinion bore. Confirm physical fit before running.

Should I pair it with a steel spur?

A steel spur is common for longevity, but a well-made aluminium spur can work if both gears are properly matched and inspected regularly.

Is modification recommended?

Do not file or re-profile the teeth. Any machining can ruin the hard coating and change the tooth geometry, leading to poor mesh and faster wear.
