Measurement with bearing shells for determining radial bearing clearance
2.2 Measure crankshaft bearing bore in direction A, B and C at two levels (out of-roundness).
3.1 Measure crankshaft bearing bore, without bearing shells, in direction A, note measurement, example: 68,51 3.2 Measure crankshaft bearing bore,
without bearing shells, in direction A, note measurement, example: 64 4 Dismount lower crankcase section (1).
5 Measure crankshaft bearing journal- example: 63,95 mm
6.1 Determine bearing shell thickness
Example: bearing bore 0 68.51 mm crankshaft journal 0 -63. 95 mm 4. 56 mm
Radial bearing clearance -0,04 mm
Test values chart "crankshaft bearing clearance"
4.52 mm:2 Bearing shell thickness 2,26 mm
6.2 Determine radial bearing clearance
Example: bearing bore 0 64, 00 mm
Crankshaft journal 0 -63. 95 mm
Radial bearing clearance 0,05 mm
7 Assign bearing shells (only for standard dimension crankshaft) example: bearing shell thickness 2,26 mm chart "test values crankshaft bearing
shells"
Upper bearing shell "yellow"
Lower bearing shell "yellow" m If the bearing shell thickness differs, install thicker bearing shell into lower crankcase section.
