Timing Belt
lnstallation
Install the timing belt in the feverse order of removal;
Only key points are described there.
NOTE: Clean the middle cover and lower cover before
installation.
1. Position the crankshaft and the camshaft pulleys as
shown betore installing the timing belt.
A. Set the crankshaft so that the No. 1 piston is at
top dead center {TDC). Align the groove on the
teeth side of the timing belt drive pulley to the V
pointer on the oil pump.
B. Align the TDC marks on intake and exhaust pul-
leys.
2. Install the timing belt tightly in the sequence
shown.

NOTE;
. Inspect the timing belt before removing the cylinder

Mark all emissions hoses betore disconnecting them.
Anti-theft radios have a coded theft protection circuit.
Be sure to get the customer's code number before- Disconnecting the battery.- Removing the No.32 (7.5 A) fuse trom the under-
hood fuse/relay box.- Removing the radio.
After service, reconnect power to the radio 8nd turn it
on.
When the word "CODE" is displaved. enter the cus-
tomer's 5-digit code to restore radio operation,
Disconnect the negative terminal from the battery.

Install the rubber seal in the groove of the cylinder
head cover. Seat the seal in the recesses for the
camshaft first, then work it into the groove around
the outside edges.
NOTE:
. Before installing the rubber seal. thoroughly
clean the seal and the groove.
. When installing, make sure the seal is seatedsecurely in the corners of the recesses with nogap.

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,

lf the crankshaft is not installed:
o Remove the rod caps and bearings. install the
ring compressor, then position the piston in the
cylinder and tap it in using the wooden handle of
a nammer.
. Position all Distons at toD dead center.
CONNECTING RODOIL HOI-E (Br8Bl onginelThe arrow must facethe timing belt sideof the engine. Theconnecting rod oil holemust lace the intak€manifold {81881 €ngine).
NOTE: Maintain downward force on the ring com-
pressor to prevent rings from expanding before
entering the cylinder bore,
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.
