1 Clean bearing points on crankshaft with a chamois leather.

2 Measure main bearing journal dia. with the  micrometer at two points (offset about 90°).

 If one of measurements obtained is not within the tolerance, machine crankshaft.

W03.20-0023-01

3 Clean bearing points in crankcase and main bearing cap with a chamois leather.

4 Insert crankshaft bearing shells (2) into the crankcase in the order marked.

 The locking lug (arrow) of crankshaft bearing shells (2) must be located in slots of the crankcase basic bores. Oil drillings in crankshaft bearing shell (2) and in crankcase must be aligned.

W03.20-0024-01

5 Insert crankshaft bearing shells (1) in marked order into main bearing caps (3, 4).

 The locking lugs (arrows) of crankshaft bearing shells (1) must be located in the slots of the main bearing caps (3).

W03.20-0025-01

6 Fit main bearing caps (3, 4) onto the crankcase.

 All main bearing caps (3, 4) have dowel pins and are marked with numbers. They must be installed in ascending order of the numbers, beginning from the front. Oil main bearing bolts (6, 7) and tighten in the specified order. First tighten the central main bearing bolts (6, 7), then the side bolts.

W03.20-0019-01

7 Use micrometer to set dial gauge and quick calipers to nominal dimension of the main bearing journal (preload 5 mm).

8 Use dial indicator and quick calipers to measure crankshaft bearing bores in crankcase at three points (A, B, C) (vertically and each about 30° away from separation points).

 If one of measurements obtained (A, B, C) is not within tolerance, replace main bearing shells to match the measured main bearing journals. Main bearing shells are factory-supplied ready for installation and also in Deviations for repair work. No reworking is permissible.

9 Take off main bearing caps (3, 4) again.
