Inspecting the crankshaft
Check that there is no play on the coppers
around the crank disks.
Inspect the large end of the connecting
rod.
Separate the crankcase halves from each
other..
This can be done without tools as the
crankshaft has a sliding fi t in the bearing
seatings.
Using a screwdriver, carefully prise off the
guide rail for the bypass channels from
the fl ywheel side of the crankcase half.
Heat the crankcase halves to approx.
150°C using a hot air gun.
Knock the halves against a wooden block
so that the bearings fall out of their seats.
Remove the gaskets with a suitable
punch.
Scrape off any gasket residue from
the cylinder base plane and from the
crankcase's contact face.
Inspecting the crankshaft
Check that there is no play on the coppers
around the crank disks.
The crankshaft cannot be reconditioned
but must be replaced if it is worn or dam-
aged.
Inspect the large end of the connecting
rod. If seizure marks, discolouration on
the sides or damaged needle holders are
found the crankshaft must be replaced.
