NOTE
If clearance between any crankshaft journal and its bearing shells exceeds 0.0060 in.
(0.152 mm), replace all bearing shells. Clearance for new parts is 0.0010–0.0040 in.
(0.025–0.102 mm).
2.
Check main bearings to crankshaft journals clearance as follows:
a.
With crankshaft removed, measure outside diameter of crankshaft main bearing journals and inside
diameter of main bearing shells in place with required torque. When installed, bearing shells are
0.001 in. (0.03 mm) larger in diameter at parting line than 90 degrees from parting line.
CAUTION
Use washers, spacers, stabilizers, or supports under main bearing bolts to prevent
bolts from bottoming out in cylinder block holes.
b.
With main bearings and crankshaft in position, place plastic gage strip (Figure 4, Item 20) on
crankshaft journal (Figure 4, Item 21). Install main bearing cap assembly, stabilizers or washers and
bolts. Torque main bearing bolts (Figure 4, Item 4) to 120–130 Ib-ft (163–177 N·m). Remove main
bearing bolts, stabilizers or washers, and cap assembly. Measure width of plastic gage with measuring
strip (Figure 4, Item 19).
