  1. Inspect journals for wear, taper and out-of-round. If specifications are exceeded, grind journals to undersize or replace crankshaft. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS  table under ENGINE SPECIFICATIONS.
  2. Inspect bearing shells for signs of fusion, pitting, burning or flaking. Observe contact pattern. Standard bearings are unmarked. Undersized bearings are stamped US025 on the back of the bearing to indicate .010" (.25 mm) undersize.
  3. Check bearing clearance using Plastigage measuring method. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS  table. Connecting rod side clearance limit is .0137" (.35 mm).
  4. To install, reverse removal procedure. Tighten connecting rod nuts to specification. See TORQUE SPECIFICATIONS  table.
