(5) Inspect connecting rods and connecting rod
caps for cylinder identification. Identify them, if nec-
essary (Fig. 78).
(6) Remove connecting rod cap. Install connecting
rod bolt protectors on connecting rod bolts (Fig. 79).
(7) Remove each piston and connecting rod assem-
bly out of the cylinder bore.
NOTE: Be careful not to nick crankshaft journals.
(8) After removal, install bearing cap on the mat-
ing rod.
INSTALLATION
(1) Before installing pistons and connecting rod
assemblies into the bore, ensure that compression
ring gaps are staggered so that neither is in line with
oil ring rail gap (Fig. 80).(2) Before installing the ring compressor, ensure
the oil ring expander ends are butted and the rail
gaps located as shown in (Fig. 80).
(3) Lubricate the piston and rings with clean
engine oil. Position a ring compressor over the piston
and rings, and tighten the compressor (Fig. 81).Be
sure position of rings does not change during
this operation.
(4) Position upper bearing onto connecting rod.
Lubricate bearing with oil.
(5) Install connecting rod bolt protectors (rubber
hose or equivalent) on the connecting rod bolts (Fig.
81).

(6) The pistons are marked with a ªFº located near
the piston pin. Install piston with this mark posi-
tioned to front of engine on both cylinder banks. The
connecting rod oil squirt hole faces the major thrust
(right) side of the engine block (Fig. 82).
(7) Rotate crankshaft until the connecting rod
journal is located in the center of the cylinder bore.
Insert connecting rod and piston into cylinder bore.
Carefully guide connecting rod over the crankshaft
journal (Fig. 81).(8) Tap the piston down in cylinder bore, using a
hammer handle. At the same time, guide connecting
rod into position on connecting rod journal.
(9) Install lower bearing shell and connecting rod
cap (Fig. 81). Install nuts on cleaned and oiled rod
bolts and tighten to 54 N´m (40 ft. lbs.) PLUS
1¤4
turn.
(10) Repeat procedure for each piston and connect-
ing rod installation.

STANDARD PROCEDURE - PISTON RING
FITTING
(1) Wipe cylinder bore clean. Insert the ring and
push down with piston to ensure squareness in bore
to approximately 12 mm (0.50 in.) from top of cylin-
der bore. Check ring gap with a feeler gauge (Fig.
83). For clearance specification (Refer to 9 - ENGINE
- SPECIFICATIONS).
(2) Check piston ring to groove side clearance (Fig.
84). For clearance specification (Refer to 9 - ENGINE
- SPECIFICATIONS)

ING ROD - REMOVAL)
(2) Remove No. 1 and No.2 piston rings from pis-
ton using a ring expander tool (Fig. 87).
(3) Remove upper oil ring side rail (Fig. 86).
(4) Remove lower oil ring side rail (Fig. 86).
(5) Remove oil ring expander (Fig. 86).
INSTALLATION
(1) Install rings with manufacturers I.D. mark (if
present) facing up, to the top of the piston (Fig. 85).CAUTION: Install piston rings in the following
order:
a. Oil ring expander.
b. Upper oil ring side rail.
c. Lower oil ring side rail.
d. No. 2 Intermediate piston ring.
e. No. 1 Upper piston ring.
(2) Install the side rail by placing one end
between the piston ring groove and the expander.
Hold end firmly and press down the portion to be
installed until side rail is in position.Do not use a
piston ring expander(Fig. 86).
(3) Install upper side rail first and then the lower
side rail.
