Connecting rod length must be measured from center of [[Crankshaft crankshaft]] journal inside diameter to center of piston pin bushing using proper caliper. Connecting rods must be the same length. Connecting rods should be checked on an alignment fixture for bent or twisted condition. Replace all components which are damaged or not within specification.
Check for improper bearing installation, wrong bearing cap or insufficient bearing clearance if side clearance is insufficient. Connecting rod may require machining to obtain proper clearance. Excessive clearance usually indicates excessive wear at crankshaft. [[Crankshaft Crankshaft]] must be repaired or replaced.
With [[Crankshaft crankshaft]] removed, install bearings and caps in original location on cylinder block. Tighten bolts to specification. On connecting rods, install bearings and caps on connecting rods. Install proper connecting rod cap on corresponding rod. Ensure bearing cap is installed in original location. Tighten bolts to specification. Using a telescopic gauge and micrometer or inside micrometer, measure inside diameter of connecting rod and main bearings bores. Subtract each crankshaft journal diameter from the corresponding inside bearing bore diameter. This is the bearing clearance.

=====''PISTONS, CONNECTING RODS & BEARINGS''=====
Install piston on connecting rod for corresponding cylinder. Ensure reference marking on top of piston corresponds with connecting rod and cap number. [[http://www.garage411.com/images/GeneralAuto/PistonPinInstall.gif See Figure]].
Using feeler gauge, check ring end gap. [[http://www.garage411.com/images/GeneralAuto/PistonRingGap.gif See Figure]]. Piston ring end gap must be within specification. Ring breakage will occur if insufficient ring end gap exists.
Cylinders must be honed prior to piston installation. Install upper connecting rod bearings. Lubricate upper bearings with engine oil. Install lower bearings in rod caps. Ensure bearing tabs are properly seated. Position piston ring gaps according to manufacturer's recommendations. [[http://www.garage411.com/images/GeneralAuto/RingPositions.gif See Figure]]. Lubricate pistons, rings and cylinder walls.
Install ring compressor. Use care not to rotate piston rings. Compress rings with ring compressor. Install plastic tubing protectors over connecting rod bolts. Install piston and connecting rod assembly. Ensure piston notch, arrow or FRONT mark is toward front of engine. [[http://www.garage411.com/images/GeneralAuto/PistonRodInstall.gif See Figure]].
Position connecting rod toward one side of crankshaft as far as possible. Using feeler gauge, measure clearance between side of connecting rod and crankshaft. [[http://www.garage411.com/images/GeneralAuto/RodClearance.gif See Figure]]. Clearance must be within specification.
Remove bearing cap. Compare Plastigage width with scale on Plastigage container to determine bearing clearance. [[http://www.garage411.com/images/GeneralAuto/BearingClearance.gif See figure]]. Rotate crankshaft 90 degrees. Repeat procedure. This is done to check journal eccentricity. This procedure can be used to check oil clearance on both connecting rod and main bearings.
''Micrometer & Telescopic Gauge Method''
A micrometer is used to determine journal diameter, taper and out-of-round dimensions of the crankshaft.
With crankshaft removed, install bearings and caps in original location on cylinder block. Tighten bolts to specification. On connecting rods, install bearings and caps on connecting rods. Install proper connecting rod cap on corresponding rod. Ensure bearing cap is installed in original location. Tighten bolts to specification. Using a telescopic gauge and micrometer or inside micrometer, measure inside diameter of connecting rod and main bearings bores. Subtract each crankshaft journal diameter from the corresponding inside bearing bore diameter. This is the bearing clearance.
