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

Technical note on the titanium 15T motor pinion

This titanium 15T motor pinion is intended for the Associated RC 18T platform and is supplied as a single 15T unit with its securing screw, intended as an aftermarket replacement or upgrade. The choice of titanium delivers improved wear characteristics and reduced rotating mass where material change is desirable, while the part is intended to swap directly with the factory 15T motor pinion without altering the nominal gear ratio.

For installation verify the pinion tooth count and orientation, then set mesh against the spur gear to achieve appropriate backlash. Engage the set screw on the motor shaft flat and then validate drivetrain rotation and axial play after final torque. Regular inspection of engagement and screw retention will maintain consistent torque transfer during operation.

In tuning contexts this 15T like-for-like replacement preserves original gear ratio while changing inertial properties and service life due to the titanium material. Select this part for maintenance-driven upgrades or to replace a worn 15T pinion without changing gearing strategy.
