Distributor Replacement
Removal:
1. Disconnect the connector from the distributor.
2. Disconnect the ignition wires from the distributor
ignition (Dl) cap.
3. Remove the mounting bolts from the distributor,
then remove the distributor from the cylinder head.

MOUNTING BOLTS8 x 1.25 mm2,1N.m {2.,1kgrf.m, 17 lbf ftl
lnstallation:
1. Bring the No. 1 piston to compression stroke TDC.
2. Coata new O-ring with engine oil, then install it.
3. Align the lug on the end of the distributor and its
mating grooves in the camshaft end, then slip the
distributor into position.
NOTE: The lug on the end of the distributor and its
mating grooves in the camshaft end are both offset
to eliminate the possibility of installing the distribu-
tor 180o out of time.
4. Installthe mounting bolts, and tighten them lightly.
5. Connect the ignition wires to the distributor ignition(Dl) cap as shown,

8. After setting the ignition timing, tighten the mount-
ing bolts.

Disconnect ground from the No. 3 terminal. The actu-
ator rod should return. lf it does not return, but the
vent hose and filter are not plugged, the solenoid
valve assembly is defective.
Repeat steps 2 through 5. and disconnect ground
from the No. l terminal. The actuator rod should
return. lf it does not return, but the vent hose and
filter are not plugged, the solenoid valve assembly
is defective.
lf you replace the solenoid valve assembly, be sure
to use new O-rings on each solenoid.
Disconnect power and ground from the 4P connector.
Disconnect the vent hose from the actuator. Connect
a vacuum pump to the actuator vent hose port, and
apply vacuum. The actuator rod should pull in com-pletely. lf not, the vacuum valve is stuck open.

Using an upward motion on the lever arm, compress
the valve spring and remove the keepers from the
valve stem. Slowly release pressure on the spring.
Repeat step 11 for the other valve in that cylinder.
Remove the valve seals (see page 6-24).

19. Insert the cross shaft through the bottom hole of
the two uprights.
Select the 7/8 in. diameter short compressor attach
ment, and fasten the attachment to the No. 4 hole of
the lever arm with the speed pin supplied.
Position the piston at TDC, and insert an air adaptor
into the spark plug hole. Pump air into the cylinder
to keep the valve closed while compressing the
springs and removing the valve keepers.

spring being compressed. Use the rear position slot
on the lever as shown.
Using a downward motion on the lever arm, com-
press the valve spring and remove the keepers from
the valve stem. Slowly release pressure on the
spring.

Inspection
Remove the cylinder head cover.
lnspect the timing belt for c.acks and oil or coolant
soaking. Replace the belt if it is oil or coolant
soaked. Remove any oil or solvent that gets on the
belt.
lnspect thisarea for wear.
After inspecting, retorque the crankshaft pulley bolt
to 177 N.m (18.0 kgnm, 130 lbf.ft).
Install the cylinder head cover (see page 6-32).

Tension Adjustment
NOTE:
. Always adjust the timing belt tension with the engine
coto.
. Always rotate the crankshaft counterclockwise when
viewed from the pulley side. Rotating it clockwise
may result in improper adiustment of the belt ten-
sion.
'1. Remove the cylinder head cover
2. Set the No. 1 piston at TDC (see page.6-12).
3. Rotate the crankshaft five or six revolutions to set
the belt.
