MG314T/0.5M Motor Gear 14T, 40Cr Steel, 0.5mm Module (3.175mm) by GPM  [MG314T/0.5M]

Summary of the 40Cr 14T Pinion

The MG314T/0.5M pinion is intended as a replacement pinion for small electric RC models that require a 0.5mm module and a motor tooth diameter of 3.175mm. Built from 40Cr steel with a hardened black finish, it is designed to improve wear resistance and provide reliable gear engagement.

Key mechanical details: 14 teeth, module 0.5mm, motor tooth diameter 3.175mm, and a round motor bore secured by two 3x3 set screws. These fixed features determine how the pinion mates with the spur gear and transmission components.

Installation and tuning notes: ensure the MG314T/0.5M tooth module, tooth count, and 3.175mm diameter match your motor and spur before fitting. Position the pinion on the shaft, check mesh and backlash, then tighten both 3x3 set screws in small increments to prevent shaft binding. Selecting a different tooth count will change gear ratios and affect speed and torque.
