Built as a service part for the Associated RC18T platform, this Delrin 54T main gear provides a simple replacement option for 1/18 scale 18T machines. The item is supplied as 1 pcs and is designed to install into typical stock gear mounts without the need for modification in most cases.
Delrin is chosen for its low friction characteristics and adequate wear life for practice sessions and club events. During installation, confirm proper pinion engagement and ensure the gearbox spins freely under load; small adjustments to motor height or pinion seating can help reduce premature wear and drivetrain noise. This is an aftermarket spare for the stated model.
Replacing a worn spur with the same 54-tooth count maintains the factory gear ratio while restoring crisp gear engagement. Keep spare screws and check bearing axial play before completing the fit to avoid misalignment issues.
