CROSSRC EMO Main 63T M1.0 Spur Gear CRXXL063TS Upgrade by GPM  [CRXXL063TS]

40Cr 63T M1.0 spur for CROSSRC EMO gearboxes

A hardened 63-tooth spur cut in 40Cr steel, this part is a direct replacement where a metric 1.0 pitch spur is required on CROSSRC EMO 1/5 and 1/6 platforms. The hardened black finish and robust material selection focus on strength and wear resistance for heavy-duty scale RC running.

Before final assembly confirm the pinion is M1.0 and set correct gear mesh and bearing alignment. Accurate mesh and straight shaft alignment reduce noise and premature wear. Follow standard RC maintenance when handling hardened steel components to avoid chipping or burrs during fitment.

This main gear gives a straightforward, material-focused 63T M1.0 upgrade for EMO gearboxes, improving toughness and delivering consistent engagement for scale driving and trail work.
