Grease the area of the crankshaft which needs to
slide into the oilseal in the left-hand crankcase (1),
and fit the crankcase centre gasket, cutting it in the
cylinder area (2) to avoid interference with the connecting rod during assembly.
N.B. Put a little grease on the gasket face of the righthand crankcase in order to help the gasket to adhere.
N.B. It is good practice to change the gaskets each
time the crankcase is opened.

After heating the left-hand main bearing, place the
left crankcase half over the right half, and use a plastic hammer to close up the two halves until they are
positioned correctly.
