Oil line

Check for hairline cracking at the soldering joints, blow compressed air through the oil line and, while doing that, check it for

unobstructed passage. In addition, check the oil line for possible scuff marks and replace the copper seal rings (8x12x1)

O-rings

Replace the O-rings during every oil filter change.

Oil pump cover

Check for score marks caused by the oil pump rotors on its inner side and, if necessary, replace it.

Oil pump shaft

Place it on a planar surface and check it for eccentricity.

Oil pump wheel

Check toothing for wear. The recess for the needle roller must not be worn out.

Oil screen

Clean the two oil screens with compressed air and petroleum.

O-rings

Check them for brittleness and, if necessary, replace them.

Oil pump rotors

Place the oil pump rotors into the engine casing and check them as shown on page 5-9.

No particles must adhere to the oil pump rotors.
