1

Mount balance shaft housing or main bearing.

2

Measure roundness of the crankshaft bearing bore in the areas (A, B, C) in two levels.

3

Measure crankshaft bearing bore the area (A); note measured value.

 Example: Diameter 62.50 mm.

4

Detach balance shaft housing.

5

Measure diameter at crankshaft bearing journal.

 Example: 57.95 mm.

6

Determine thickness of bearing shells.
