Direct fit main shaft for Yokomo RS1.0

The Yokomo RS-644 Main Shaft is a vital replacement part for the RS1.0 chassis that helps preserve accurate motor mount alignment. It supports the centre pulley and spur gear arrangement to keep driveline geometry consistent, and is compatible with RSR-010 and RSR-LFGT3RTR models for both repairs and performance-minded maintenance.
Remark :
Due to limited stock availability, please notice that some Yokomo items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will the RS-644 fit a modified RS1.0 setup?

The RS-644 is a direct fit when the RS1.0 motor mount and pulley positions are retained. If you have custom brackets or altered gear spacing, check clearances before installation.

How do I know when to replace the main shaft?

Inspect for play, scoring, or bent surfaces after crashes or during routine service. If you notice excessive slop or gear misalignment, replace the RS-644 to restore reliable operation.

Is special tooling needed to install this shaft?

Basic hobby tools are sufficient: small hex drivers, pin spanner or pliers for pulley removal, and a clean workbench. Follow the RS1.0 service procedure to ensure correct reassembly.
