CARRIER - INSTALLATION).
(16) Install oil pan (Refer to 9 - ENGINE/LUBRI-
CATION/OIL PAN - INSTALLATION).
(17) Install cylinder head (Refer to 9 - ENGINE/

CONNECTING ROD BEARINGS
STANDARD PROCEDURE
CONNECTING ROD - FITTING
(1) For measuring connecting rod bearing clear-
ance procedure and use of Plastigage (Refer to 9 -
ENGINE - STANDARD PROCEDURE). For bearing
clearance refer to Engine Specifications. (Refer to 9 -
ENGINE - SPECIFICATIONS)
NOTE: The rod bearing bolts should not be reused.
(2) Before installing the NEW bolts the threads
should be oiled with clean engine oil.
(3) Install each bolt finger tight then alternately
torque each bolt to assemble the cap properly.
(4) Tighten the connecting rod bolts using the 2
step torque-turn method. Tighten according to the
following values:
CAUTION: Do not use a torque wrench for the sec-
ond step.
1. Tighten the bolts to 27 N·m (20 ft. lbs.).
2. Tighten the connecting rod bolts an additional
1/4 TURN.
(5) Using a feeler gauge, check connecting rod side
clearance (Fig. 66). Refer to clearance specifications
(Refer to 9 - ENGINE - SPECIFICATIONS).
PISTON RINGS
STANDARD PROCEDURE
PISTON RING - FITTING
(1) Wipe cylinder bore clean. Insert ring and push
down with piston to ensure it is square in bore. The
ring gap measurement must be made with the ring
positioning at least 12 mm (0.50 inch) from bottom of
cylinder bore. Check gap with feeler gauge (Fig. 67).
Refer to Engine Specifications.
(2) Check piston ring to groove side clearance (Fig.
68). Refer to Engine Specifications.

PISTON & CONNECTING ROD (Continued)
REMOVAL
(1) Using a suitable ring expander, remove upper
and intermediate piston rings (Fig. 69).
(2) Remove the upper oil ring side rail, lower oil
ring side rail and then oil ring expander from piston.
(3) Clean ring grooves of any carbon deposits.
INSTALLATION
NOTE: The identification mark on face of upper and
intermediate piston rings must point toward top of
piston.
Install rings with manufacturers identification
mark facing up, to the top of the piston (Fig. 70).
CAUTION: Install piston rings in the following
order:
1. Oil ring expander.
2. Upper oil ring side rail.
3. Lower oil ring side rail.
4. No. 2 Intermediate piston ring.
5. No. 1 Upper piston ring.

PISTON RINGS (Continued)
(1) Install oil ring expander (Fig. 70).
(2) Install upper side rail first and then the lower
side rail. Install the side rails by placing one end
between the piston ring groove and the oil ring
expander. Hold end firmly and press down the por-
tion to be installed until side rail is in position. Do
not use a piston ring expander (Fig. 71).
(3) Install No. 2 piston ring and then No. 1 piston
ring (Fig. 70).
(4) Position piston ring end gaps as shown in (Fig.
72).
(5) Position oil ring expander gap at least 45° from
the side rail gaps but not on the piston pin center or
on the thrust direction. Staggering ring gap is impor-
tant for oil control.

REMOVAL
(1) Disconnect negative battery cable.
(2) Support engine under oil pan with wooden
block and floor jack.
(3) Remove three right side engine mount vertical
bolts to front engine bracket.
