This Delrin 54-tooth main gear is supplied as a maintenance spare for the Associated RC18T platform and suits 1/18 scale 18T models. Delivered as 1 pcs, the part is designed to sit in common stock gear mounts without machining in most standard configurations.
Delrin offers a low friction surface and reasonable wear characteristics for club and practice use. When installing, check gear mesh alignment and confirm the gearbox rotates smoothly under load; minor motor height or pinion seating changes can cut noise and reduce wear. This item is an aftermarket accessory for the stated chassis.
Maintaining the same 54T tooth count preserves the original gearing, so fitting an identical replacement restores expected acceleration and engagement. Also check fasteners and bearing condition while replacing the spur to ensure long term reliability.
