Refer to specifications (Fig. 8).
(2) Check piston ring to groove clearance: (Fig. 9).
Refer to specification (Fig. 8).
PISTON RINGS—INSTALLATION
(1) The No. 1 and No. 2 piston rings have a differ-
ent cross section. Install rings with manufacturers
I.D. mark facing up, to the top of the piston (Fig. 10).
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. 11).
(3) Install upper side rail first and then the lower
side rail.
(4) Install No. 2 piston ring and then No. 1 piston
ring (Fig. 12).
(5) Position piston ring end gaps as shown in (Fig.
13).
(6) 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.
INSTALLING PISTON AND CONNECTING ROD
ASSEMBLY
(1) Before installing pistons and connecting rod as-
semblies into the bore, ensure that compression ring
gaps are staggered so that neither is in line with oil
ring rail gap.
(2) Before installing the ring compressor, make
