Splitting the crankcase halves
- Before opening the crankcase, it is advisable to
check the axial clearance of the crankshaft. To do
this, use a plate and a support with appropriate tool
dial gauge.
- Upper clearances are an indication of wear on
the surfaces of the crankshaft casing support.
- Remove the 10 crankshaft coupling screws.
- Separate the crankcase while keeping the crank-
shaft in one of the two halves of the crankcase.
- Remove the crankshaft.
- Remove the half crankcase coupling gasket.
- Remove the two screws and the internal cover
shown in the diagram.
- Remove the oil guard on the flywheel side.
- Remove the oil filter fitting shown in the diagram.
- Check the axial clearance on the connecting rod.
- Check the radial clearance on the connecting rod.
-Check the surfaces that limit the axial free-play
are not scored and measure the width of the crank-
shaft between these surfaces, as shown in the
diagram.
- If the axial clearance between crankshaft and
crankcase is exceeding and the crankshaft does
