Precision Delrin main gear for Associated RC18T

This Delrin 56-tooth main gear is supplied as 1 pc and serves as an aftermarket replacement compatible with Associated RC18T spur carriers and gearboxes. The geometry is maintained to allow direct replacement without altering motor mount positions.

Manufactured from acetal Delrin, the part offers reduced friction and stable wear characteristics compared with common injection-moulded plastics, supporting consistent tooth contact under typical 1/18 electric off-road torque loads. It is suitable for users seeking dependable, low-drag spur performance for maintenance or tuning experiments.

Technical fitting notes: inspect pinion and spur tooth profiles prior to installation, set backlash using a paper shim or feeler gauge for precise clearance, and verify rotation through the full suspension travel to detect binding. Use the gear for planned maintenance cycles, spur replacement after wear, or controlled testing during drivetrain setup.

What inspection steps before fitting?

Check pinion tooth profile and bore concentricity, confirm tooth count and pitch match, and ensure the carrier seats correctly before torqueing fasteners.

Recommended mesh tolerance?

Set a minimal but consistent backlash using paper or a shim, then run the drivetrain at low speed to confirm even engagement across several rotations before final securing.

Material considerations for durability?

Delrin delivers predictable wear and lower friction than softer plastics; for extended high-load applications evaluate reinforced or metal spurs depending on duty cycle.
