The 41-tooth main spur is a direct aftermarket option for CROSSRC EMO platforms. Constructed from 40Cr steel with a hardened black coating, the spur keeps the original M1.5 metric pitch so gearbox alignment and geometry remain unchanged.
Use this part to replace a worn factory spur or when upgrading for increased durability on tough terrain and heavier loads. The steel build prioritises longevity while retaining the correct tooth profile for existing M1.5 pinion gears.
Packing contents appear below and compatibility is listed after that to help confirm fit before purchase.
Fit as a like-for-like swap, confirm correct pinion engagement and backlash, and run a short test to ensure smooth gear mesh before full use.
