Crankshaft Main Bearing: Service and Repair
Mounting Crankshaft Radially In Bearings
1. Remove crankshaft.
2. Disassemble and clean engine.
3. Clean and inspect crankshaft.
4. Install and tighten bearing cap to 30 Nm
5. Measure and note bearing bore diameter.
6. Measure and note crankshaft bearing journal diameter.
7. Match bearing shells. Refer to illustration.
Example:
Bearing bore diameter
62.51 mm
Crankshaft journal diameter
- 57.95 mm
_______
4.55 mm
Radial bearing play
- 0.04 mm
_______
Bearing shell thickness
4.51 mm/2 = 2.25 mm
CAUTION: When determining different bearing shells, match thicker bearing shell to the bearing cap.
NOTE: Top bearing shell "blue". Bottom bearing shell "blue".
8. Calculate the likely radial bearing play.
9. Blow bolt holes clean.
