Main Bearings: Installation

Be sure that all bearing caps are installed in their original location. Coat rear mating surface of rear main bearing cap with oil resistant sealer.

If bearing clearance using standard size bearing inserts is excessive, a.001" or.002" undersize bearing half may be used in combination with a standard size bearing half. If.002" undersize bearing is used on more than one journal, they may be positioned in the cylinder block rather than in the bearing cap. If standard and.002" undersize combination do not bring clearance to within specified limits, the crankshaft will have to be refinished and undersize bearings installed.
