Tools Required

1. Coat the crankshaft bearings with engine oil.
2. Install the upper crankshaft bearings into the engine block crankshaft journals.
3. Install the lower crankshaft bearings into the crankshaft bearing caps.
4. Install the crankshaft.
5. Inspect the crankshaft end play with the crankshaft bearings installed.
6. Check for permissible crankshaft end play. Refer to Engine Mechanical Specifications .



7. With the crankshaft mounted on the front and rear crankshaft bearings, check the middle crankshaft journal for permissible out-of-round (runout). Refer to Engine Mechanical Specifications .




Important: Grease the crankshaft journals and lubricate the crankshaft bearings slightly so that the plastic gaging thread does not tear when the crankshaft bearing caps are removed.

8. Inspect all of the crankshaft bearing clearances using a commercially available plastic gaging (ductile plastic threads).
9. Cut the plastic gaging threads to the length of the bearing width. Lay them axially between the crankshaft journals and the crankshaft bearings.



10. Install the crankshaft bearing caps.

Notice: Refer to Fastener Notice in the Preface section.

11. Install the crankshaft bearing cap bolts using the J 45059 or the KM-470-B .

Tighten
Tighten the crankshaft bearing cap bolts to 50 N·m (37 lb ft). Tighten the crankshaft bearing cap bolts 45 degrees plus 15 degrees.




12. Remove the crankshaft bearing caps.
13. Measure the width of the flattened plastic thread of the plastic gaging using a ruler. (Plastic gaging is available for different tolerance ranges.)
14. Inspect the bearing clearances for permissible tolerance ranges. Refer to Engine Mechanical Specifications .
