Pinion details and fitment notes

The MG5020TS is an aftermarket 1/8-scale motor pinion suitable for ARRMA and TRAXXAS vehicles, designed to deliver consistent engagement in hobby drivetrains. Constructed from 20Cr steel with a hardened black surface treatment, it offers better wear resistance than many lighter materials.

Key parameters are 20 teeth, a 1.0mm module, and a 5.0mm round bore for the motor shaft. The unit secures with two 4x4 set screws; confirm compatibility with your motor and spur gear prior to purchase.

This pinion is recommended when durability and reliable mesh are priorities. Always verify module, tooth count and bore alignment to your current gear train to ensure correct operation.

What should I inspect on my spur gear to match this pinion?

Check that your spur gear uses a 1.0mm module and that tooth counts create the gearing you expect. Also verify the motor flange and shaft are compatible with a 5.0mm round-bore pinion.

Any tips for maintaining mesh and reducing wear?

Set mesh with a thin, even gap at rest, tighten the two set screws evenly, and periodically check for backlash or burrs. Regular inspection helps preserve the hardened finish and prevents premature wear.
