1. Remove the oil pump (see page 8-8).
2. Remove the baffle plate (see step 7 on page 7-12).
3. Measure the connecting rod end play with a feeler
gauge (A) between the connecting rod (B) and
crankshaft (C).
4. If the connecting rod end play is out-of-tolerance,
install a new connecting rod and recheck. If it is still
out-of-tolerance, replace the crankshaft (see page
7-12).
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; dial reading should not
exceed the service limit.
6. If the end play is out-of-tolerance, replace the thrust
washers and recheck. If it is still out-of-tolerance,
replace the crankshaft (see page 7-12).

Crankshaft Main Bearing Replacement
1. Remove the main caps and bearing halves (see
page 7-12).
2. Clean each main journal and bearing half with a
clean shop towel.
3. Place one strip of plastigage across each main
journal.
NOTE: If the engine is still in the car when you bolt
the main cap down to check the clearance, the
weight of the crankshaft and drive plate will flatten
the plastigage further than just the torque on the
cap bolt and give you an incorrect reading. For an
accurate reading, support the crank with a jack
under the counterweights, and check only one
bearing at a time.
4. Reinstall the bearings and caps, then torque the
bolts (see step 21 on page 7-25). Do not rotate the
crankshaft.
5. Remove the caps and bearing half, and measure
the widest part of the plastigage.
6. If the plastigage measures too wide or too narrow,
(remove the engine if it’s still in the car), remove
the crankshaft, and remove the upper half of the
bearing. 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
again. If the proper clearance cannot be obtained
by using the appropriate larger or smaller bearings,
replace the crankshaft and start over.

1. Letters or bars have been stamped on the end of
the block as a code for the size of each of the four
main journal bores.
If you can not read the codes 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.
2. Numbers or bars have been stamped on the
crankshaft No. 1 web as a code for the main journal
sizes.
3. Use the crankshaft bore codes and journal codes to
select the appropriate main bearings from the table.

1. Remove the connecting rod cap and bearing half
(see page 7-12).
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 cap, and torque the
bolts (see step 18 on page 7-25). Do not rotate the
crankshaft.
5. Remove the rod cap and bearing half and measure
the widest part of the plastigage.
6. If the plastigage measures too wide or too narrow,
remove the upper half of the bearing, 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
