Overview of the Motor Pinion

The MG315T/0.5M motor pinion is an aftermarket replacement designed to match motors with a 3.175mm tooth diameter, presenting a 15-tooth count and a 0.5mm module. Fabricated from 40Cr steel and heat treated with a darkened finish, it aims to resist wear and preserve consistent gear engagement.

Dimensions of note are 15T, 0.5mm module, and a 3.175mm motor tooth diameter; the round bore fits standard motor shafts. Two 3x3 set screws secure the pinion in place, offering a straightforward clamping method for retention on the shaft.

During installation, align the teeth with the mating spur and confirm proper mesh before first full-power operation. Tighten the set screws evenly and recheck after a brief run to ensure there is no axial movement or misalignment.

What is the correct installation procedure for this pinion?

Slide the pinion fully onto the motor shaft, position it for the desired mesh, then tighten both 3x3 set screws evenly; run the model briefly and recheck screw tightness and mesh.

How should I set gear mesh with this 0.5mm module pinion?

With the spur installed, adjust motor position until there is a small amount of backlash and smooth rotation by hand; tighten set screws and verify no binding at full rotation.

What torque or tightness should I use on the set screws?

Tighten the 3x3 set screws snugly but avoid over-torquing; they should clamp the pinion without deforming the bore. Recheck after initial runs.
