MR-4TCSD Front One-Way & Solid Axle Ring and Drive Gear (Graphite) - YOKSD643G by Yokomo  [YOKSD643G]

This RC-grade graphite ring gear and drive gear set is made for MR-4TCSD front one-way and solid axle installations. The components are supplied as replacement drivetrain gears intended for direct-fit use where the front one-way or solid axle assembly requires graphite parts.

Focus on fit and routine service: confirm the MR-4TCSD front assembly type before ordering, inspect current gear mesh and bearing condition, and choose this set when worn or damaged gears produce play or inconsistent engagement. The graphite material gives stable dimensional behavior suitable for regular maintenance cycles in hobby RC drivetrains.

Installation notes: isolate power and secure the chassis before starting, disassemble the front drive housing following your chassis manual, clean all mating surfaces, fit the gears to maintain correct mesh, verify alignment with the front one-way or solid axle components, and rotate the assembly by hand to confirm smooth engagement before reassembling electronics and testing at low throttle.

Tuning role: this gear set is intended as a service replacement that preserves consistent tooth engagement and drivetrain feel, and it is useful when adjusting gear mesh or diagnosing front-end driveline behavior during setup sessions.
