Rod Bearings
CAUTION:
DO NOT use a new bearing half with an old bearing half.
- Upper and lower bearing halves are not interchangeable. Install bearings in pairs. DO NOT file rods or bearing caps. Before installing rod bearings, hold a straightedge across threads of connecting rod bolts.
- Ensure connecting rod bolt threads contact straightedge in all areas. If threads fail to contact straightedge, bolts are stretched and must be replaced. Ensure rod bearing cap face surfaces are not damaged. If fractured rod and joint face are damaged, engine damage may occur.
- Bearing shells must be installed with tangs inserted into machined grooves in rods and bearing caps. Ensure hole in upper bearing half aligns with oil hole in connecting rod. Connecting rod bearings are available in .001" (.025 mm) and .010" (.250 mm) undersize.
- Using a dial indicator, test connecting rod cap side play. Rest indicator tip against connecting rod cap being tested. Move connecting rod to rear of its travel. Zero dial indicator. Move connecting rod forward of its travel and read dial indicator. See CONNECTING RODS table under ENGINE SPECIFICATIONS. Apply light coat of engine oil to connecting rod threads before tightening nut to specification. See TORQUE SPECIFICATIONS .
