Compact motor pinion upgrade

The MG317T/0.5M is a compact pinion sized for motors matching the specified module and tooth diameter. Manufactured from 40Cr steel and given a hardened black finish, it offers stronger wear resistance than many stock pinions and helps preserve consistent torque delivery under routine use.

Specs summary: 17 teeth, module 0.5mm, motor tooth diameter 3.175mm, round motor bore, retained by two 3x3 set screws. Check motor shaft dimensions and gear mesh clearance before fitting to avoid mismatches.

Fitting guidance: slide the pinion onto the motor shaft ensuring concentric seating, set the correct mesh with the spur gear, and tighten the two set screws evenly. Use this pinion to experiment with small changes to the final drive ratio for controlled driveline behavior.

How do I check my motor shaft for compatibility?

Measure the motor tooth diameter and confirm the required module is 0.5mm. If both measurements match 3.175mm and 0.5mm respectively, the pinion should fit, but also verify bore type and set screw clearance.

Any tips for securing the pinion reliably?

Align the pinion concentrically, pre-tighten one 3x3 set screw, rotate the shaft slightly and then tighten the second screw evenly. Recheck mesh and test at low speed before full use.
