Fitting Bearings

OIL CLEARANCE
1. Measure the journal outside diameter as shown in the illustration. Refer to the illustration of the Crankshaft Table for Specifications.





PLASTIGAGE (OIL CLEARANCE) MEASUREMENT
1. Remove oil from journal and bearing shell.
2. Install crankshaft.
3. Cut plastigage to same length as width of the bearing and place it in parallel with the journal axis.
4. Install the main bearing cap carefully and tighten the bolts to specified torque.

CAUTION: Do not rotate crankshaft or the plastigage will be smeared.

5. Carefully remove the bearing cap and measure the width of the plastigage at the widest part using the scale on the plastigage package. Refer to the illustration of the Crankshaft Table for Specification and proper clearances. If the clearance exceeds the specified limits. Replace the main bearing(s) and if necessary have the crankshaft machined to next undersize.

CAUTION: Do not rotate crankshaft or the Plastigage may be smeared.
