(60°C). Ensure rod is properly positioned with piston. See
Fig. 34 .
Fitting Pistons
Measure clearances with cylinder block supported on work bench. Check clearance of piston-to-cylinder
bore. Piston diameter is stamped on top of piston in millimeters.

Rod Bearings
Mark rod caps for reinstallation. Use Plastigage to measure bearing oil clearance. Tighten connecting rod
nuts to 22 ft. lbs. (30 N.m) when measuring oil clearance. DO NOT turn additional 90 degrees. Measure
connecting rod side play. Replace or machine as necessary. See
CRANKSHAFT, MAIN &
CONNECTING ROD BEARINGS table under ENGINE SPECIFICATIONS. Lubricate bolt threads when
installing connecting rod caps. Tighten evenly to specification in several steps. See TORQUE

Crankshaft & Main Bearings
Main bearing caps are marked with matching journal for installation in original position. See Fig. 35 . Use
Plastigage to measure oil clearance. Tighten main bearing cap bolts to 48 ft. lbs. (65 N.m) when measuring
oil clearance. DO NOT turn additional 90 degrees. Measure crankshaft end play. See THRUST BEARING.
