Fine Tuning Gear Engagement with Serpent SER120112

The Serpent SER120112 pinion is a 64P, 25-tooth aluminium gear made for precise tooth contact in RC drivetrains. It is aimed at hobbyists seeking reliable meshing without excessive cost.

Longevity and On-Track Performance

This hard aluminium pinion withstands frequent running while keeping mass low. Reduced rotational weight helps the motor spool up faster and can improve throttle response on the track.

Where This Pinion Works Best

The 64P 25T specification suits many on-road and light off-road models. Use it when swapping ratios or replacing worn pinions to regain correct mesh and smooth power transfer.

Can I run the Serpent SER120112 on my standard 540 motor?

Yes. The 64P 25T pinion fits common 540-size and similar motor setups as long as the shaft size and bore compatibility are checked.

Any tips for quieter gear operation?

Set a small clearance between pinion and spur and ensure both gears are clean and free of burrs. Proper shimming and tightening of the motor mount will reduce noise.

Is aluminium better than plastic for pinions?

Aluminium offers improved wear resistance over plastic for many users, though it can transfer more shock to the drivetrain. Choose based on your use case and maintenance habits.

How often should I replace the pinion?

Replacement frequency depends on running time and conditions. Inspect teeth after heavy sessions and swap it at the first sign of pronounced wear to protect the spur.
