Precision 48P 28T Pinion

The Yokomo YOKPG4828 pinion is a 48 pitch, 28-tooth unit crafted for electric model drivetrains and finished with an ultra-hard surface as stated in the product title. It is suitable as a replacement or spare part where 48 pitch gearing is specified and is commonly used when adjusting the balance between acceleration and top speed.

Installation notes: confirm correct engagement with the spur gear and ensure the motor shaft is correctly located with bearings operating freely; do not overtighten the pinion against the shaft which can load bearings, and rotate the drivetrain by hand to check for smooth mesh before powered testing. Make gradual backlash adjustments to refine gear contact.

Tuning role: swapping pinions within the 48 pitch family changes the gear ratio and therefore vehicle behavior; this pinion is a practical option for fine-tuning gearing to suit circuit layout and motor power characteristics while remaining within 48-pitch specifications.
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.

Does this fit standard 48P spur gears?

Yes. This pinion conforms to 48 pitch geometry and is intended to mesh cleanly with standard 48P spur gears of matching profile.

How should I approach backlash when installing?

Start with a small clearance and test by hand-turning the drivetrain; increase or decrease backlash in small increments until engagement is smooth and noise is minimized, avoiding heavy tooth pressure.

What benefit does the hardened finish provide?

The ultra-hard surface treatment improves wear resistance under normal electric drivetrain loads, helping maintain accurate tooth profiles for longer and reducing the frequency of replacements.
