Piston & Rod Assembly

  1. Install piston, connecting rod and bearings in corresponding cylinder. Connecting rods and bearing caps have numbers stamped on them. Ensure arrows on top of pistons point toward front of engine.
  2. Lubricate connecting rod bearings with oil. Install bearing caps, ensuring numbers match and are aligned. Install NEW connecting rod bolts, and tighten to 17 ft. lbs. (23 N.m). Using Torque Angle Gauge (11-2-110), tighten connecting rod bolts an additional 70-degree torque angle.
NOTE: If piston and connecting rod assembly have been separated, ensure piston is installed with arrow pointing toward right when connecting rod numbers are facing you.
