1

Remove balance shaft housing or main bearing.

2

Measure roundness of crankshaft bearing bore in areas (A, B, C) at two levels using dial  indicator.

 Commercially available devices/tools
Quick calipers for internal measurements

3

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

 Example: Diameter 62.50 mm.

4

Measure diameter at crankshaft bearing journal.

 Commercially available devices/tools
Outside micrometer

 Example: 57.95 mm.

5

Determine thickness of bearing shells.
