9-5 Arc Sport Wagon (9600) V6-3.0L Turbo (B308) (2002)
Clean the crankshaft and measure the crankpins with a micrometer. Measurements should be taken at several points round the circumference. The
out-of-round (ovality) of the main journals must not exceed 0.003 mm. If the measurements are close to or in excess of this wear, the crankshaft
should be ground down to the specified undersize.
Checking bearing clearances
Main bearings
Measure clearances with (45) 30 06 558 Plastigage
Important: When measuring clearances with Plastigage, make sure that none of it gets into the oil holes.
1. Position the engine with the cylinder head surface downwards so that the weight of the crankshaft will not affect the measurements.
2. Clean the parts that are to be measured. Place a strip of Plastigage along the shaft.
