Scale 48-Pitch 28T Pinion

The Yokomo YOKPG4828 is a 28-tooth, 48 pitch pinion intended for scale electric car drivetrains, featuring an ultra-hard surface finish as noted in the product description. It functions as a replacement or upgrade option where 48 pitch gears are specified and sits in the common tooth-count range used for balancing acceleration and top speed.

Installation notes: verify correct mesh with the matching spur, check motor shaft alignment and bearing freedom, avoid pressing the pinion too far onto the shaft to prevent bearing preload, and rotate by hand to confirm smooth engagement before running the model under power. Make small backlash adjustments rather than large corrections to reach the ideal engagement.

Tuning role: choosing different pinion tooth counts within 48 pitch setups directly changes overall gear ratio, so swapping pinions like this one is a straightforward way to tune acceleration and top speed according to track demands and motor characteristics.
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.

What gear profile and tooth count does this model use?

This model is a 48 pitch pinion with 28 teeth, matching the designation shown in the product name.

Any tips to avoid bearing damage during fitment?

Avoid hammering the pinion onto the shaft; instead, press it evenly and confirm shaft alignment so bearings are not subjected to axial load. Check for free bearing rotation after fitting.

Will this pinion change my car's gearing much?

Yes. The tooth count directly affects the final drive ratio. Moving up in teeth will tend to increase top speed and reduce acceleration, while fewer teeth do the reverse.
