Connecting Rod and Crankshaft End Play Inspection
1. Remove the oil pump (see page 8-16).
2. Remove the baffle plates (see step 8 on page 7-13).
3. Measure the connecting rod end play with a feeler
gauge between the connecting rod and the
crankshaft.
4. If the connecting rod end play is beyond the service limit, install a new connecting rod, and recheck. If it
is still beyond the service limit; replace the
crankshaft (see page 7-13). 5. Push the crankshaft firmly away from the dial
indicator, and zero the dial against the end of the
crankshaft. Then pull the crankshaft firmly back
toward the indicator, the dial reading should not
exceed the service limit.
6. If the end play is beyond the service limit, replace the thrust washers and recheck. If it is still beyond
the service limit, replace the crankshaft (see page
7-13).

Crankshaft Main Bearing Replacement
1. To check the main bearing-to-journal oil clearance,
remove the lower block and the bearing halves
(see page 7-13).
2. Clean each main journal and bearing half with a clean shop towel.
3. Place one strip of plastigage across each main journal.
4. Reinstall the bearings and lower block, then tighten the bolts to 29 N·m (3.0 kgf·m, 22 lbf·ft) 56 ° in
thepropersequence(seestep19onpage7-27).
NOTE: Apply new engine oil to the bolt threads and flanges.
 Do not rotate the crankshaft during inspection.
5. Remove the lower block and the bearings again, and measure the widest part of the plastigage. 6. If the plastigage measures too wide or too narrow,
remove the crankshaft, and remove the upper half
of the bearing. Install a new, complete bearing with
the appropriate color code(s), 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 the current one), and
check again. If the proper clearance cannot be
obtained by using the appropriate larger or smaller
bearings, replace the crankshaft, and start over.

3. Use the crank bore codes and crank journal codes
to select the appropriate replacement bearings
from the following table.
NOTE: Color code is on the edge of the bearing.
 When using bearing halves of different colors, it does not matter which color is used in the top or
bottom. 1. Remove the oil pump (see page 8-16).
2. Remove the baffle plates (see step 8 on page 7-13).
3. Remove the connecting rod cap and the bearing
half.
4. Clean the crankshaft rod journal and the bearing half with a clean shop towel.
5. Place plastigage across the rod journal.
6. Reinstall the bearing half and connecting rod cap, and tighten the bolts to 20 N·m (2.0 kgf·m, 14 lbf·ft)90 ° (K20Z2 engine) or 29 N·m (3.0 kgf·m,
22 lbf·ft) 90 ° (K20Z3 engine).
NOTE:  Apply new engine oil to the bolt threads and flanges.
 Do not rotate the crankshaft during inspection.
7. Remove the connecting rod cap and the bearing half, and measure the widest part of the plastigage.
