Fitting tips

1. Heat the crankcase halves (around 100 to 120 °C) to remove and fit the bearings without force; put the new bearings in the freezer to help them go in.
2. Never hit the outer race of a bearing mounted on the shaft, or the inner race of a bearing mounted in the crankcase.
3. Fit the oil seals perfectly square, with greased lips.
4. Close up with a complete engine gasket kit and check that the crankshaft turns freely.
5. Take the opportunity to check the gearbox bearings and refill with fresh oil.
