Removing crankshaft sealing ring - belt pulley side
1. Make a 3-mm hole at the front of the sealing ring using an angle drill. Grease the drill in order to bind the chips caused by drilling. Screw a sheet
metal screw with a washer approximately 5 mm into the bore hole.
ATTENTION: Particles of dirt can damage the engine.
^
When working on the engine, absolute cleanliness is essential.
2. Position a lever tool on the sheet metal screw, place a wooden wedge between the lever tool and the crankcase and lever out the sealing ring.
Carefully remove any residual dirt on the crankshaft flange.
ATTENTION: The crankshaft flange can be damaged if not cleaned correctly.

acetone.
