Associated RC 18T Precision Titanium 15T Motor Pinion TAR015T by GPM  [TAR015T]

15T titanium motor pinion tailored for Associated 18T

This 15-tooth titanium motor gear is specified for the Associated RC 18T and is supplied as a single pinion with its securing screw, intended strictly as an aftermarket replacement or upgrade component. Titanium offers a good balance of wear resistance and lower rotating mass where the material is appropriate, and the part swaps directly for the stock 15T motor pinion on the designated chassis.

Fitment requires confirming the tooth count and orientation before installation, then setting correct mesh with the spur gear to achieve the desired backlash. Ensure the set screw clamps to the motor shaft flat and re-check drivetrain rotation and any end float after final tightening. Regular checks for screw security and contact wear will help avoid drivetrain issues during running.

Used as a like-for-like 15T replacement the pinion keeps the original ratio but can alter inertia and longevity due to the material change. It is suitable for maintenance upgrades and for replacing worn 15T pinions without modifying overall gearing.
