The contact surface (3) on the crankshaft flange (2), the sealing lip (1d) and the protective lip (1s) of the end cover with radial shaft sealing ring (1) must not be oiled or greased. Oil or grease on the slanting webs of the sealing lip (1d) of the end cover with radial shaft sealing ring (1) prevent back-transport of engine oil in the crankcase.

During use of an insertion tool one must absolutely ensure correct alignment of the sealing lip (1d) otherwise deficient sealing can arise.

Clean

1 Clean and degrease sealing surfaces on cylinder crankcase (4) and on oil pan (5) in the area of the end cover with radial shaft sealing ring (1) as well as the contact surface (3) on crankshaft flange (2) .

Do not use any sharp-edged tools or abrasive paper for cleaning. These can damage the sealing surface on the cylinder crankcase (4), the oil pan (5) or the contact surface (3) on the crankshaft flange (2).

2 Clean and degrease sealing surface on the new end cover with radial shaft sealing ring (1).
