2) Install rings on piston with TOP mark facing upward.
Recessed edge on outside of center ring must face piston pin (down).
Position ring gaps on piston at 120-degree intervals.
Connecting Rod Bearings
Mark rod caps for reinstallation. Use Plastigage to measure
bearing clearances. Measure connecting rod side play. Replace or
machine as necessary. See CRANKSHAFT, MAIN & CONNECTING ROD BEARINGS
table under ENGINE SPECIFICATIONS. Tighten evenly to specification in
several steps. See TORQUE SPECIFICATIONS.
Crankshaft & Main Bearings
