14. Apply liquid gasket to the rubbe. seal at the eightcorne.s of the recesses.
NOTE:
. Use liquid gasket, Part No. 08718 - 0001.. Check that the mating surfaces are clean and dry
before applying liquid gasket.
a Do not install the parts if 20 minutes or more
have elapsed since applying liquid gasket.
Instead,.eapply liquid gasket after removing oldresidue.
r After assembly, wait at least 20 minutes beforefilling the engine with oil.
Apply liquid gasket tothe shaded areas.

Piston
lnstallation
'1.
Before installing the piston, apply a coat ofengine oil to the ring grooves and cylinder bores.
lf the crankshaft is already installed:
. Remove the connecting rod caps and slip short
sections of rubber hose ove. the threaded ends
of the connecting rod bolts.
a Install the ring compressor, check that the bear'
ing is securely in place, then position the piston
in the cylinder and tap it in using the wooden
handle of a hammer.
Stop after the ring compressor pops free and
check the connecting rod-to-crank journal align-
ment before tapping piston into place.
. Install the rod caps with bearings, then torque
the nuts,

cylinder and tap it in using the wooden handle of
a nammer.
. Position all Distons at toD dead center.

BING COMPRESSORUse the wooden handleof a hammer to push ortap the piston into thecylinder bore.
Piston Rings
Replacement
1.Using a ring expander, remove old piston rings.
Clean all ring g.ooves thoroughly.
NOTE:
. Use a squared-oJf broken ring or ring groove
cleaner with blade to fit piston grooves.
. Top ring groove is 1.0 mm (0.039 in) wide, sec-
ond groove is 1.2 mm (0.047 in) wide. and oil
ring groove is 2.8 mm (0.110 in) wide.. File down blade if necessary.
CAUTION: Do not use a wire brush to cloan thr
ring lands, or cut ring lands dsopo. with cl€aning
tool.
NOTE: lf the piston is to be separated from the con-
necting rod, do not install new rings yet.
Install new rings in the prope. sequence and posi-
tion (see page 7-18).
NOTE: Do not use old piston rings.

preload closest to the standard mean value of 2.50
N.m (25.5 kgJ.cm, 22 lbf.in).
NOTE: Changing the 79.5 mm shim to the next size
will increase or decrease tapered roller bearing

Recheck the tapered roller bearing preload.
How to select the correct 79.5 mm shim:- 1) Compare the tapered roller bearing preload you
get with the 79.5 mm shim that was removed
with the specified mean preload of 2.50 N.m(25.5 kgf .cm. 22 lbf.inl.-2) lf your measured tapered roller bearing preload
is less than specified, subtract your's from the
soecified.
lf your's is more than specified, subtract the
specified from your measurement.
For example with a 1 .38 mm (O.O543 in) shim:
@ specified 2.50 N.m (25.5 kgf.cm, 22 lbf.in)- you measure 0.54 N.m (5.5 kgt.cm, 5lbt'in)
2.0 N.m {20 kgf.cm, 18lbt.in} less
@you measure 3.29 N.m {33.5 kgl.cm, 29 lbl.in)- specified 2.50 N.m {25.5 kgf.cm, 22 lbf.in)
0.8 N.m (8 kgf.cm, 7lbt.in) more
3) Each shim size uD or down from standard
makes about O.3-O.4 N.m (3-4 kgf.cm,
2.6-3.5 lbf.in) difJerence in tapered roller
bearing preload.
a In example @, your measured tapered roller
bearing preload was 2.O N.m (20 kgf'cm,
I 8 lbl.in) less than standard so you need a
79.5 mm shim five sizes thicker thsn stan-
dard {trv the 1.53 mm (0.0602 inl shim and
recheck).
a In example @ your's was O.8 N.m (8
kgf.cm, 7 lbJ.in) more than standard, so
you need a thrust shim two sizes thinner (try
the 1.32 mm (0.0520 in) shim and recheck).
After adjusting the tapered .oller bearing preload, as-
semble the transmission, and installthe transmission
housing {see section 13).
