4.5.16 Crankcase
Figure 58
– Split Crankcase
Now the crankcase halves can be split: remove the nuts from the retained studs and then set about
carefully tapping each retained stud (located at the front and back of the case) with a suitable soft
hammer until the case halves start to separate.
Carefully pull each case half away from the crankshaft, taking care not to let the camshaft fall. Remove
the camshaft from the case and set it aside.
The oil filler support fitting, arrowed in Figure 58, can be removed now if necessary (i.e. if the case is to
be line-bored). Otherwise it can be left in place.
Remove the main bearing shells. Remove all ‘O’ rings. The front and rear retained studs should be left
in the cases at this stage; if necessary they will be removed after the inspection stage.
