Before the bearing clearance is checked in connection with fitting of new bearings, the crankshaft journals ovality and taper must be checked. The
clearances are checked with Plastigage, part number 30 06 558, available in three dimensions. Type PG-1 (green) must be used.
Important: When using the Plastigage to measure play, be careful not to get any in the oil holes.
Measure ovality with a micrometer in two positions 90 degrees from each other. Clearance can be checked with a Plastigage as follows:
1. Clean the parts to be measured so that they are dry and free from oil and dirt. Place a strip of Plastigage along the shaft.
2. Fit the bearing cap.
Tightening torque 20 Nm + 70° (15 ft. lbs. + 70°)
The crankshaft must remain absolutely still while measurement is in progress.
3. Remove the bearing cap. The strip of Plastigage should now have adhered to either the bearing cap or the main journal.
