Crankshaft & Main Bearings

  1. Mark bearing caps for reassembly. Measure journal diameter, out-of-round, taper and oil clearance. If measurement is not within specification, replace main bearings and/or machine crankshaft. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS  table under ENGINE SPECIFICATIONS.
  2. Align thrust bearing surfaces, and measure crankshaft end play. See THRUST BEARING below.
