Small motor pinion built for durability

The MG218T/0.5M pinion is an aftermarket RC replacement manufactured from 40Cr steel with a hardened black finish to boost wear resistance and maintain smooth gear mesh. It carries 18 teeth at a 0.5mm module and a 2.2mm motor tooth diameter, compatible with many small motor designs.

Installation is simple: the part uses a round motor bore and secures with two 3x3 set screws. Always double-check motor shaft diameter, module rating and tooth count to ensure a correct match before fitting.

This pinion works well as a direct swap or when upgrading to a tougher steel gear for longer service life under tuning and regular driving. Fit with basic hand tools and tighten the set screws evenly to preserve alignment.

Can I use this pinion with any 0.5mm module motor?

Only if the motor accepts an 18T pinion at 0.5mm module and the motor tooth diameter is 2.2mm; confirm the shaft size and module before purchase.

How should I prepare the motor shaft before fitting?

Clean the shaft, remove any burrs, slide the pinion onto the round bore and secure it with the two 3x3 set screws, tightening a little at a time to center the gear.

Does hardened 40Cr steel reduce maintenance needs?

The hardened finish increases wear resistance, which typically means fewer replacements compared with softer stock gears under normal operating conditions.
