Kyosho FW05-R/FW05RR Transmission Shaft FW05-021 by 3Racing  [FW05-021]

Replacement transmission shaft for FW05-R and FW05RR

This transmission shaft is a scale replacement intended for Kyosho FW05-R and FW05RR chassis, listed under part number FW05-021. It is supplied as a direct-fit service item for routine gearbox and drivetrain maintenance when the original shaft shows wear.

The component is designed to restore alignment and rotational transfer inside the model transmission, offering like-for-like fitment with existing gearbox elements. Installation commonly requires partial disassembly of the gearbox and careful alignment with the current gears and bearings to reduce the risk of premature wear.

Treat this shaft as a maintenance spare when planning repairs or setup changes: inspect mating surfaces, confirm correct gear mesh and bearing condition, and check for smooth rotation before running the car. The part is intended for standard tuning and maintenance on the FW05-R/FW05RR platform and is not for applications beyond scale RC models.
