CAUTION: Care should be taken not to
damage the fractured rod and cap joint face
surfaces or damage to the engine may occur.

NOTE: Connecting rod bolts are retained in the
connecting rod cap with a light press fit. The
connecting rod bolts have been torqued to yield
at least twice and must be discarded. Use a
hammer and punch to drive connecting rod bolts
from connecting rod caps.
Using new connecting rod bolts, attach
connecting rod cap and lower connecting rod
bearing to connecting rod and upper connecting
rod bearing to prevent mixing parts and damaging
the fractured joint face surfaces.

NOTE: Any piston rings that are removed from
piston should be discarded and replaced with
new piston rings.
If
piston ring replacement is required, use a
suitable piston ring expander. Remove two
compression rings. Remove two oil ring rails and
expander by hand.
Mark connecting rod cap to ensure reassembly
with same piston and installation in same
cylinders from which they were removed.
NOTE: The piston and piston pin (6 1 35) are a
matched set. Keep pistons, piston pin, piston
rings, connecting rods and connecting rod
bearings together in proper cylinder order.
Using Piston Pin Tool D81 L-6 135-A or equivalent,
press piston pin from piston and connecting rod.

37. loosen crankshaft main bearing cap adjusting
screws (6C360).
38. Remove bearing main cap retaining bolts. These
are torque-to-yield bolts and should not be
reused.
39. NOTE: The location of the main bearing caps and
the main bearing inserts should be identified.
When the engine is assembled, bearings which
are to be reused should be installed in their
original positions.
Remove each main bearing cap and lower
crankshaft main bearing (6333). Keep each cap
and lower crankshaft main bearings together.
40. CAUTION: When removing the crankshaft,
use care not to damage any of the bearing
surfaces on the crankshaft.
Remove crankshaft.
4 1 . Clean and inspect crankshaft and cylinder blocks.
Replace worn or damaged components as
required.
Assembly
1 . NOTE: Before assembling cylinder blocks, all
sealing surfaces must be clean and free of chips,
dirt, paint and foreign material. Also, make sure
coolant and oil passages are clear.
lubricate and install crankshaft main bearings
into cylinder blocks. Install crankshaft main
bearings and crankshaft thrust main bearing
(6337) into main bearing caps.
2.
Install crankshaft into cylinder blocks.
