Dismantle the ball-bearings from the crankcase
halves.
Heat the crankcase halves to 110°C using a hot air
gun. See figure 70.
5
Knock the crankcase half against a wooden block
so that the ball-bearing falls out. See figure 71.
6
Dismantle the sealing rings from the crankcase
halves.
Use a suitable punch or sleeve and knock out
the sealing rings with the help of a hammer. See
figure 72. Do this while the crankcase half is still
warm if possible.
Now clean the crankcase halves and crankshaft.

7.22 Cleaning and inspection

The crankshaft cannot be reconditioned but must
be replaced if it is worn or damaged.
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. See figure 73.
