Technical Delrin 55T spur for Kyosho V One RRR drivetrains

The V3R-0855/V2 Delrin 55T spur is engineered as a replacement or performance hop-up for the Kyosho V One RRR. Its thermoplastic composition reduces internal friction relative to harder gear materials while preserving accurate tooth profiles for reliable engagement under typical electric touring loads.

Assembly guidance: perform a pre-fit inspection of spur teeth and gearbox bearings, set gear mesh precisely with the chosen motor pinion to avoid preload, and verify smooth rotation across the gearbox after installation. Expect slight material compliance from Delrin; monitor mesh uniformity and correct any radial runout or binding.

Tuning and compatibility: use this Delrin spur when refining drivetrain feel or restoring a worn spur to nominal engagement. Coordinate pinion selection and secure mounting to maintain torque transfer and drivability during acceleration and corner exits.

What pinion considerations apply with this spur?

Select a pinion that matches the intended gear ratio and avoids extreme mesh offsets; oversize pinions can increase load and accelerate wear on Delrin teeth.

How should I verify mesh after fitting?

Set a nominal backlash, rotate the gearbox through full turns while observing tooth contact, and listen for chatter or binding; adjust pinion spacing and retest until engagement is even.

Any bearing or gearbox prep recommended?

Inspect and, if needed, replace worn bearings, clean the gearbox interior of debris, and ensure shafts run true to optimise load distribution on the Delrin spur.
