connecting rod assemblies from the engine,
rotate crankshaft so that each connecting rod
is centered in cylinder bore.
NOTE: Connecting rod bearing caps are not inter-
changeable and should be marked before removing
to ensure correct reassembly.
CAUTION: DO NOT use a number stamp or a punch
to mark connecting rods. Damage to connecting
rod could occur.
(2) Mark connecting rod and bearing cap positions
using a permanent ink marker or scribe tool (Fig.
78).
CAUTION: Care must be taken not to damage the
fractured rod and cap joint face surfaces, as engine
damage may occur.

8189 Connecting Rod Guides into the connecting rod
being removed (Fig. 79). Remove each piston and rod
assembly out of cylinder bore.
NOTE: Be careful not to nick crankshaft journals.
(4) After removal, install bearing cap on the mat-
ing rod to prevent damage to the fractured cap to rod
surfaces.
PISTON RINGS—INSTALLATION
(1) The No. 1 and No. 2 piston rings have a differ-
ent cross section. Ensure No. 2 ring is installed with
manufacturers I.D. mark (dot) facing up, towards top
of the piston (Fig. 80).
CAUTION:
Install piston rings in the following
order:
(2) Oil ring expander.
(3) Upper oil ring side rail.
(4) Lower oil ring side rail.
(5) No. 2 Intermediate piston ring.
(6) No. 1 Upper piston ring.
(7) 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 during this step (Fig. 81).
(8) Install upper side rail first and then the lower
side rail.
(9) Install No. 2 piston ring and then No. 1 piston
ring (Fig. 82).
(10) Position piston ring end gaps as shown in
(Fig. 83).
(11) Position oil ring expander gap at least 45°
from the side rail gaps but not on the piston pin cen-
ter or on the thrust direction. Staggering ring gap is
important for oil control.
