Gasket ring versions

I	Elastomer gasket ring 1 sealing lip -1-; with garter spring
II	PTFE gasket ring multiple sealing lips -2-; without garter spring

Note t  Do no moisten the PTFE gasket ring with oil before inserting. The shaft must also be free from oil and grease. t  Never install an elastomer gasket ring (old version), if a PTFE gasket ring (new version) was fitted. t  An elastomer gasket ring can be replaced by a PTFE gasket ring.

Marking on crankshaft bearing for ordering replacement parts The crankshaft bearing shells are factory-classified. Align the top crankshaft bearing shells according to the marking on the cylinder block (stamped letters).   Note t  -Arrow- points to the belt pulley. t  Identification of the bearing is visible without removal of the oil pan. Colour coding of bearing shells matches the letters on the cylinder block

R	=	red
G	=	yellow
B	=	blue
W	=	white

The bottom crankshaft bearing shells are always supplied as replacement parts with the colour coding “yellow”.

Removing and installing sensor rotor –  Replace sensor rotor -2- and bolt -1- each time they are slackened.   Note t  After being attached a second time, the attachment point in the sensor rotor -2- is sufficiently misshapen that the bolt head -1- rests against crankshaft -3--arrows- and the sensor rotor is positioned loosely below the screw. t  Assembly only possible in one position -holes offset-.
