Modifi Motor Pinion Gear

Stock pinion gears are often made of softer metals that wear down quickly under high-stress conditions. This hardened steel gear offers significantly better durability and wear resistance, which helps maintain consistent power transfer and prevents the gear from stripping during intense operation.

No, this specific pinion gear is engineered for seamless integration with the Marui motor series. While it is designed for standard AEG systems, you should verify that your motor shaft matches the Marui specification before installation.

Yes, you will typically need a dedicated pinion gear removal and installation tool to safely press the old gear off and secure the new one onto the motor shaft. Attempting to force it on without the proper tool can damage the motor shaft or the gear itself.

If your current gear is stripped or chipped, replacing it with this steel option will likely resolve the grinding noise and restore proper engagement. However, if the noise is coming from the motor bearings or internal components, replacing the pinion gear alone may not solve the issue.

It is generally good practice to inspect your bevel gear whenever you replace the pinion. If the bevel gear shows signs of significant wear, installing a new, hardened steel pinion against it can cause premature wear on both parts due to mismatched tooth profiles.
