NOTE: Do not rotate crankshaft during bearing-to-journal oil clearance. DO NOT file, shim or scrape bearings or caps in an attempt to modify oil clearance.

NOTE: A number or bars is stamped on side of each connecting rod and cap as a code, indicating connecting rod bore. A letter or bars is stamped on crankshaft counterweights as a code, indicating connecting rod journal diameter. See Figure. Both codes are necessary when ordering replacement bearings.
