Quick Tip: Before installing the 1312304027 clutch hub, clean the main shaft thoroughly and check for burrs or wear on the splines. A misaligned or dirty spline can cause grinding in low gears — a common issue after rebuilds. Lightly grease the internal teeth with moly-based assembly lube, not regular oil, to prevent dry start-up damage.
