Yokomo PG-4818A 18T Hard Coated Pinion Overview

The Yokomo PG-4818A is an 18-tooth pinion constructed from hard coated aluminium for use in 48 pitch gear systems. Its tougher surface finish helps resist abrasion while keeping the gear light for better rotational dynamics.

Compatibility and Typical Use

Suited to RC cars that require precise gear engagement, the PG-4818A works with matching 48 pitch spurs to ensure smooth drivetrain operation. The reduced mass of the aluminium design supports improved acceleration and responsive performance.

Installation and Care

Fit the Yokomo PG-4818A only with a 48 pitch spur and confirm the motor shaft diameter is correct. Check gear mesh and set screw tightness after installation and re-check after a few runs.
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 shaft sizes are common for this pinion?

Motor shafts vary, so verify the shaft diameter before purchase. The PG-4818A will fit motors that accept 48 pitch pinions when the bore matches the shaft size.

Should I change grease often?

Keep gears clean and apply gear-compatible lubricant as needed based on driving conditions. Heavy dirt or water exposure means more frequent care.

Can I drill or modify the gear?

Avoid modifying the pinion unless you know the consequences for balance and strength. Any machining could void performance and increase wear risk.

How do I check for correct mesh?

Use a feeler or paper method to set a small clearance between teeth, then tighten mounting screws and test at low speed before full use.
