Shimming crankshaft

Using depth gauge, BMW # 00 2 550, measure distance from crankshaft web to housing joint line = dimension "B".




Measure distance from left engine housing joint face to spacing washer contact face = dimension "A".

Dimension "A" minus dimension "B" = crankshaft endplay.

Note:

• Allow for the thickness of the compressed gasket (approx. 0.4 mm/0.016 in).
• On the magnet side, the spacing washer is always 1.0 mm (0.04 in) thick.

Select a suitable spacing washer to ensure that the correct endplay is obtained.

Crankshaft endplay: 0.1...0.3 mm (0.004...0.012 in).

Note:

• Shim the balancing shaft in the same way as the crankshaft.
• Install spacing washers only on the clutch side.

Fit left engine housing and screw down.

Note: Note the two fasteners in the oil filter housing.

Cut off protruding gasket.

Tightening torque:

• Threaded fasteners of engine housing: 10 Nm
