48 Pitch Pinion — 28 Tooth Scale Part

The Yokomo YOKPG4828 pinion is manufactured as a 48 pitch, 28-tooth component intended for use in scale electric model drivetrains. The ultra-hard finish described in the item name provides improved surface durability compared with untreated stock parts, making it suitable as a replacement or spare for 48 pitch systems.

Installation notes: inspect spur mesh and confirm correct axial placement on the motor shaft, ensure bearings are free to turn, avoid compressing bearing seals when setting the gear, and always hand-rotate the drivetrain to detect any tight spots before applying power. Make modest backlash corrections incrementally to find the best engagement.

Tuning role: swapping to a different 28T vs other tooth counts on 48 pitch gearing changes the gear ratio and will alter acceleration and top-end behavior; use pinion swaps to tailor performance to track surface and motor characteristics while keeping within 48-pitch compatibility.
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.

Is this pinion compatible with standard 48-pitch spurs?

Yes. The YOKPG4828 uses 48 pitch geometry and is intended to mesh with standard 48-pitch spur gears of matching tooth profile.

What pre-checks should I do after fitting the pinion?

After fitting, check for smooth manual rotation, confirm there is no binding at the motor mount, and verify backlash is within a small range so the teeth engage cleanly without heavy contact.

How does the hardened finish affect longevity?

The ultra-hard surface treatment increases wear resistance, helping tooth profiles remain accurate longer under typical electric motor loads, which can extend service life compared with untreated gears.
