Crankshaft (VW Passat B6)

Note: Before removing the crankshaft, ensure proper storage place to avoid damaging the sensor gear.

Note: To perform installation work, the engine must be secured to the engine and gearbox retainer.

Removal and installation the sensor gear

Note: Replace sensor gear 2 after each removal of bolts 1.

After the second tightening, the screwing point of the countersunk head screws in the sensor gear is deformed so much that the screw heads rest on the crankshaft 3 and stop pressing the sensor gear (fig. 2.152).

The sensor gear can only be installed in one position, the holes are offset.

Main bearing markings

The upper bearing shells of the correct thickness are installed in the cylinder block at the factory. Colored marks are used to indicate the thickness of the bearing shells (fig. 2.153).

The bearing thickness that should be used in a specific location is indicated on the lower seating surface of the cylinder block by letter marking:

• G - yellow;
• B - blue;
• W - white.

Note: If the color marks are no longer legible, use the blue bearing shell.

Note: Lower main bearing shells are supplied as spare parts with a "yellow" colour marking.
