Main Bearing Clearance
Check clearance by using gaging plastic according to following procedure.
1. Remove bearing caps.
2. Clean bearings and main journals.
3. Place a piece of gaging plastic the full width of bearing (parallel to crankshaft) on journal, avoiding oil hole.
4. Install bearing cap and evenly torque cap bolts to specified torque.
Bearing cap MUST be torqued to specification in order to assure proper reading of clearance.
Tightening Torque (a): 54 Nm (39.0 ft. lbs.)
NOTE: Do not rotate crankshaft while gaging plastic is installed.
5. Remove cap and using scale on gaging plastic envelope, measure gaging plastic width at its widest point. if clearance exceeds its limit, replace
bearing. Always replace both upper and lower inserts as a unit.
A new standard bearing may produce proper clearance. If not, it will be necessary to regrind crankshaft journal for use of 0.25 mm undersize
bearing.
After selecting new bearing, recheck clearance.
Bearing clearance:
Standard: 0.020 - 0.040 mm (0.0008 - 0.0016 inch)
Limit: 0.060 mm (0.0023 inch)
