PLASTIGAGE PROCEDURE
1. Remove oil film from surface to be checked. Plastigage is soluble in oil.
2. Place a piece of Plastigage across the entire width of the bearing shell in the cap approximately 6.35 mm (1/4 inch) off center and away from the
oil holes. (In addition, suspected areas can be checked by placing the Plastigage in the suspected area). Torque the bearing cap bolts of the bearing
being checked to the proper specifications.
3. Remove the bearing cap and compare the width of the flattened Plastigage with the metric scale provided on the package. Locate the band closest
to the same width. This band shows the amount of clearance in thousandths of a millimeter. Differences in readings between the ends indicate the
amount of taper present. Record all readings taken. Plastigage generally is accompanied by two scales. One scale is in inches, the other is a metric
scale.
NOTE: Plastigage is available in a variety of clearance ranges. Use the most appropriate range for the specifications you are checking.
