Crankshaft Bore Code Location

Letters or bars have been stamped on the end of the engine block as a code for the size of each of the four main journal bores.

Use them, and the numbers stamped on the crankshaft (codes for main journal size), to choose the correct bearings. If the codes are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.

Scheme 747: Connecting Rod Bearing Clearance Inspection
  1. Remove the connecting rod cap and the bearing half (see «CRANKSHAFT AND PISTON REMOVAL»(ref-294717-S10761147132008081300000) ).
  2. Clean the crankshaft rod journal and bearing half with a clean shop towel.
  3. Place a strip of plastigage across the rod journal.
  4. Reinstall the bearing half and the cap, and tighten the bolts. NOTE: Apply new engine oil to the bolt threads and flanges. Do not rotate the crankshaft during inspection. Tightening Torque: 20 N.m (2.0 kgf.m, 15 lbf.ft)+90°
  5. Remove the rod cap and the bearing half and measure the widest part of the plastigage. Connecting Rod Bearing-to-Journal Oil Clearance Standard (New): 0.020-0.044 mm (0.0008-0.0017 in.) Service Limit: 0.050 mm (0.0020 in.)
  6. If the plastigage measures too wide or too narrow, remove the upper half of the bearing, then install a new, complete bearing with the same color code, and recheck the clearance. Do not file, shim, or scrape the bearings or the caps to adjust clearance.
  7. If the plastigage shows the clearance is still incorrect, try the next larger or smaller bearing (the color listed above or below that one), and check clearance again. If the proper clearance cannot be obtained by using the appropriate larger or smaller bearings, replace the crankshaft and start over (see «CRANKSHAFT AND PISTON REMOVAL»(ref-294717-S10761147132008081300000) ).

Connecting Rod Journal Code Locations

Numbers or bars have been stamped on the side of each connecting rod as a code for the size of the big end. Use them, and the letters or bars stamped on the crank (codes for rod journal size), to choose the correct bearings. If the codes are indecipherable because of an accumulation of dirt and dust, do not scrub them with a wire brush or scraper. Clean them only with solvent or detergent.

  1. Remove the engine/transmission (see «ENGINE REMOVAL»(ref-294701-S37258878062008081300000) ).
  2. Remove the transmission (see «TRANSMISSION REMOVAL»(ref-372405-S08042130282010092500000) ).
  3. Remove the drive plate (see «DRIVE PLATE REMOVAL AND INSTALLATION»(ref-372405-S22173913832010092500000) ).
  4. Remove the cylinder heads: J35A6 engine (see «CYLINDER HEAD REMOVAL»(ref-294693-S22121878322008081300000) ) '07 model J35A7 engine (see «CYLINDER HEAD REMOVAL»(ref-294693-S25769468732008081300000) ) '08-09 models J35A7 engine (see «CYLINDER HEAD REMOVAL»(ref-294693-S00800205632008081300000) )
