Fitting tips

1. Heat the crankcase (around 100 to 120 °C) to remove the old bearing and fit the new one without force.
2. Only push on the race that is the tight fit: outer race in the crankcase, inner race on the shaft.
3. Check which way round it goes if the bearing has a shielded side.
4. Close up with new gaskets or a complete engine gasket kit.
