Fitting tips

2. Fit the gaskets dry, except where the workshop manual specifies sealant.
3. Replace the O-rings at the same time: a crushed O-ring can't be reused.
4. With the cases split, also replace the crankshaft bearings and oil seals and check the gearbox bearings.
5. Tighten the crankcases and covers in a criss-cross pattern to the manufacturer's torque, then fill up with oil and coolant.
