NOTE
The gauging plastic shall be positioned the full width of the bear-
ing and centered on the bearing journal when the bearing cap
is installed.
Position gauging plastic on bearing journal (3) the fill width of the bearing (4) and parallel to the
center line of the crankshaft.
NOTE
Identification numbers on connecting rods and rod caps must be
installed on the same side.
Check identification number on side of connecting rod (6) and install corresponding rod cap (2).
Secure rod cap (2) to connecting rod (6) with two nuts (1) and tighten to 44-52 lb-ft (60-71 N•m).
Remove two nuts (1) and rod cap (2) from connecting rod (6).
Measure gauging plastic at its widest point.
If the gauging plastic tapers toward the middle or ends, there is a difference in clearance indicating
taper, low spot, or irregularity of bearing or crankshaft journal. If gauging plastic indicates more
than 0.001 in. (0.025 mm) taper, measure crankshaft journal with micrometer (para. 2-17).
NOTE
It is acceptable to use a standard bearing with a 0.001 in.
(0.025 mm) undersize bearing to obtain the proper rod bearing
clearance. If unable to produce proper clearance, replace
crankshaft.
If the measurement is within specification, 0.002-0.004 in. (0.051-0.102 mm) bearing is satisfactory.
If measurement is not within specifications, a 0.001 in. (0.025 mm) undersize bearing may produce
proper bearing clearance. Replace bearings and repeat steps 9 through 15.
Remove gauging plastic.
Apply OE/HDO to rod bearings. Check identification number on side of connecting rod (6) and
install corresponding rod cap (2).
Secure rod cap (2) to connecting rod (6) with two nuts (1) and tighten to 44-52 lb-ft (60-71 N•m).
Rotate crankshaft (5) to ensure crankshaft (5) rotates.
Repeat steps 2 through 19 for remaining pistons and connecting rods.
