This 63-tooth spur is produced in hardened 40Cr steel and matches the metric 1.0 pitch used on CROSSRC EMO platforms. It is intended as a direct replacement or upgrade to improve tooth life under load for 1/5 and 1/6 scale applications.
During installation verify pinion compatibility with M1.0 pitch and set gear mesh carefully. Proper alignment of bearings and shafts will help reduce premature wear and running noise. Handle hardened components with caution to prevent chipping while fitting.
A material-led 63T M1.0 replacement for EMO gearboxes that balances strength and consistent gear engagement for long trail sessions and scale running.
