GPM alloy main gear adaptor for RC18T service

This alloy main gear adaptor is supplied as a single-piece set for the Associated RC 18T platform and includes the retaining screws, designated AR115. It is provided as an aftermarket replacement to restore secure seating between the spur gear and gearbox and to address wear on the original adaptor.

Installation notes: slide the adaptor onto the main gear shaft, align the adaptor with the spur gear teeth, tighten screws evenly and confirm minimal axial runout before final torque. Use the correct hex driver size and moderate torque to protect fasteners and verify gear mesh and backlash after installation.

Tuning and service role: the adaptor maintains concentric alignment of the spur gear during rebuilds and maintenance, helping to keep gear engagement consistent for predictable drivetrain response during operation.

What does the AR115 package contain?

The package includes one alloy main gear adaptor AR115 and the set of retaining screws required for mounting.

Is AR115 a direct fit for standard RC18T gear shafts?

AR115 is specified for Associated RC 18T gear assemblies; confirm shaft diameter and gearbox spacing before installation to ensure a direct fit.

Recommended setup checks after fitting?

Verify shaft runout, set correct backlash, and rotate the gear assembly by hand to confirm smooth engagement prior to powered testing.
