Replacement pinion for compact motors

The MG317T/0.5M pinion is sized for motors that match the specified module and motor tooth diameter. Manufactured from 40Cr steel and finished in hardened black, it aims to reduce wear relative to typical stock gears and help keep drivetrain output consistent in everyday use.

Key specs: 17 teeth at module 0.5mm, motor tooth diameter 3.175mm, round motor bore, retained by two 3x3 set screws. Confirm motor shaft measurements and mesh parameters before purchasing to ensure compatibility.

Application notes: use the pinion when replacing worn gears or when tuning final drive ratios. Install concentrically, set the correct mesh with the spur gear, and tighten the two set screws evenly to maintain alignment. Small adjustments to pinion size will produce predictable effects on acceleration and top speed.

What measurements should I confirm before buying?

Measure your motor tooth diameter and confirm the pinion module is 0.5mm. Also check bore type and available clearance for the two 3x3 set screws to ensure a correct fit.

Is there any break-in required after installation?

After installing and setting the mesh, run the drivetrain at low speed for a short period to confirm alignment and to let the parts seat. Recheck set screws and mesh after the initial run.
