17 Tooth Motor Pinion for 0.5M Systems

The MG217T/0.5M pinion is produced in 40Cr steel and treated with a hardened black surface to resist wear. It provides a 17-tooth profile compatible with a 0.5mm module and a 2.2mm motor bore for common electric model setups.

The pinion uses a round motor hole and is fixed to the shaft with two 3x3 set screws for reliable retention. Always confirm the motor bore size and module before fitting to guarantee proper engagement with the spur gear.

Use this pinion when changing gear ratios or replacing a damaged pinion; the hardened finish helps extend service life but does not modify tooth geometry, so verify mesh clearances and backlash after installation and testing.

What is the correct installation process?

Slide the pinion onto the motor shaft, align teeth with the spur, then tighten the two 3x3 set screws evenly. Check for endplay and spin the motor to confirm smooth operation before sealing the gear box.

Should I change mesh after first run?

Yes. Hardened pins may bed slightly; run the model briefly, then recheck and fine tune mesh and backlash to prevent premature wear.

Can this pinion be used for tuning final drive ratios?

Yes. Swapping to the MG217T/0.5M alters the pinion tooth count and will change the final drive ratio. Recalculate the ratio and test performance to find the desired balance between speed and torque.
