Technical 55T Delrin Spur for V One RRR

High-precision Delrin 55-tooth spur intended for use on Kyosho V One RRR and V One RRR Evo chassis, identified as model V3R-0855. The Delrin material lowers sliding friction at the gear interface compared with common nylon blends, helping to maintain consistent torque transfer and more immediate throttle response without altering ratio or tooth count.

Workshop fitment is direct: remove the gearbox cover, verify hub concentricity and motor pinion alignment, mount the Delrin spur on the original hub, and fine-tune mesh and lateral clearance before reassembly. During installation, inspect bearing play and mating surfaces to avoid intermittent vibration or premature wear.

For racers and tuners, the low-friction spur reduces internal drivetrain drag and sharpens transient throttle behaviour on lightweight electric setups. Evaluate mesh, pinion depth, and audible cues during run-in to confirm optimal setup. This component is intended solely for RC model applications.

What is the best method to set final mesh?

Set a minimal lateral gap across the pinion face, rotate the drivetrain to check for binding, then tighten gradients and recheck under light motor load to confirm no interference.

Is Delrin suitable for high-power setups?

Delrin reduces friction but monitor heat and contact patterns; in very high-power applications review mating components and consider reinforced hardware as required.

How to inspect mesh wear quickly?

Run the drivetrain by hand to feel for rough spots, inspect tooth contact with a thin smear of marking compound, and check bearings for smooth rotation to identify early wear.
