PISTON & CONNECTING ROD (Continued)
INSTALLATION
(1) Install piston rings on piston (Refer to 9 -
ENGINE/ENGINE BLOCK/PISTON
INSTALLATION)
(2) Before installing pistons and connecting rod
assemblies into the bore, be sure that compression
ring gaps are staggered so that neither is in line with
oil ring rail gap (Fig. 59).
(3) Before installing the ring compressor, make
sure the oil ring expander ends are butted and the
rail gaps located as shown in (Fig. 59). As viewed
from top.
(4) Immerse the piston head and rings in clean
engine oil, slide the ring compressor, over the piston
(Fig. 60). Be sure position of rings does not
change during this operation .

(5) The directional stamp on the piston should face
toward the front of the engine (Fig. 56).
(6) Rotate crankshaft so that the connecting rod
journal is on the center of the cylinder bore. Lubri-
cate connecting rod journal with clean engine oil.

(7) Install connecting rod upper bearing half into
connecting rod. Install Special Tool 8189, connecting
rod guides onto connecting rod (Fig. 58).
(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) Remove Special Tool 8189, connecting rod
guides.
NOTE: The connecting rod cap bolts should not be
reused.
(10) Before installing the NEW bolts, the threads
should be coated with clean engine oil.
(11) Install connecting rod lower bearing half into
connecting rod cap. Install connecting rod cap.
(12) Install each bolt finger tight then alternately
torque each bolt to assemble the cap properly.
(13) 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.
(14) Using a feeler gauge, check connecting rod
side clearance (Fig. 61). (Refer to 9 - ENGINE -
SPECIFICATIONS) for connecting rod side clearance.
(15) Install Balance Shaft Carrier Assembly (Refer
to 9 - ENGINE/VALVE TIMING/BALANCE SHAFT
CARRIER - INSTALLATION).
(16) Install oil pan (Refer to 9 - ENGINE/LUBRI-
CATION/OIL PAN - INSTALLATION).
(17) Install cylinder head (Refer to 9 - ENGINE/
CYLINDER HEAD - INSTALLATION).
