Check Crankshaft Bearing Clearance (With Plastigage)

NOTE:
- Crankshaft removed.
- Do not rotate the crankshaft.
Lay out plastigage.

Lay out plastigage (flexible plastic thread) around the entire width of the crankshaft bearing journal (1).
NOTE:
The bolts can be reused for checking the crankshaft bearing play.

Install the 4 lower crankshaft bearings (3) and the lower crankshaft thrust bearing (4).
Install the crankshaft bearing cap tie plate (2).
Install the 10 inner crankshaft bearing cap tie plate bolts (1).
CAUTION:
Refer to Fastener Caution .

Tighten the 10 inner crankshaft bearing cap tie plate bolts in a sequence as shown and in the following order:
1. Tighten the inner crankshaft bearing cap tie plate bolts to 25 N.m (18 lb ft).
2. Tighten the inner crankshaft bearing cap tie plate bolts an additional 60 degrees. Use EN-470 - B wrench.
3. Tighten the inner crankshaft bearing cap tie plate bolts an additional 15 degrees. Use EN-470 - B wrench.
Remove the crankshaft bearing cap tie plate bolts and the crankshaft bearing cap tie plate.
NOTE:
When reading the value, do not confuse millimeters and inches on the measuring scale.

Measure the crankshaft bearing play.
1. Compare the width of the flattened plastic thread (arrow) to the measuring scale (1).
2. The crankshaft bearing play should be 0.007 - 0.031 mm (0.00028 - 0.00122 in).
