Place the extractor plate.
Fit the three fixing screws.
Adequately centre the plate with refer-
ence to the crankshaft.
Tighten the three fixing screws.
Screw the long threaded end of the ex-
tractor screw on the extractor plate un-
til the crankcase half on the clutch side
starts to get detached. Facilitate the
detachment of the crankcase by tap-
ping the secondary shaft with a rubber
mallet, being careful that the crank-
case half gets detached evenly. Be ex-
tremely careful not to tap the seal
surfaces.
Check the thrust washer of the main
shaft. When detaching the crankcase,
the washer may get glued inside the
crankcase halves.
Once the crankcase halves have been
detached, remove the extracting tool
before the crankcase halves are fully
apart.
