lgnition Timing Inspection and Setting
2.
1.Check the idle speed, and adjust it if necessary (see
section 1 1).
Pull out the service check connector 2P (BRN and
BLK wires) from the connector holder located under
the dash on the front passenger side, then connect
the scs service connector (P/N 07PAz - 0010100) to
it.
Start the engine. Hold the engine at 3,000 rpm with
no load (A/T in N or E, Mff in neutral) until the
radiator fan comes on, then let it idle.
Connect the timing light to the No. I ignition wire,
then point the light toward the pointer on the timing
belt cover.
Check the ignition timing in no load conditions:
headlights, blower fan, rear window defogger, and
air conditioner are not operating.
lgnition Timing:
M/T: 16" 12" BTDC (RED) idling in neutral

Loosen the distributor mounting bolts, and turn the
distributor ignition (Dl) housing counterclockwise to
advance the timing or clockwise to retard the tim-
t no,

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).
3.
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.
Set the No. 1 piston at TDC.
Loosen the adjusting bolt 1/2 turn (180') only.

Mark the rocker arms, then remove them.
Reinstall the camshaft and holders. Tighten the
camshaft holder bolts in a crisscross pattern, begin-
ning with the inner bolts.

Seat the camshafts by pushing them toward the dis-
tributor end of the head with a screwdriver.
Zero the dial indicator against the end of the
camshaft, push the camshaft back and forth and
read the end play.

Unscrew the camshaft holder bolts two turns at a
time, in a crisscross pattern, Then remove the
camshaft holder bolts from the cvlinder head.
Lift the camshafts out of the cylinder head. wipe
them clean, then inspect the lift ramps, Replace the
camshaft if any lobes are pitted, scored, or exces-
sively worn.
Clean the camshaft journal surfaces in the cylinder
head, then set the camshaft back in Dlace. Place aplastigage strip across each journal.
Install the camshaft holders. and torque the bolts tothe values and in the sequence shown on page 6-31.
NOTE: Do not rotate the camshafts during inspection.

you must replace the cylinder head.. lf the camshaft has not been replaced, first check
total runout with the camshaft suoDorted on V-
blocks.

- lf the total runout of the camshafts is within tol-
erance, replace the cylinder head
- lf the total runout is out of tolerance, replace the
camshafts and recheck. lf the oil clearance is still
out of tolerance, replace the cylinder head.

7.Place the rocker arms on the pivots and the valve
stems. Put the rocker arms in their original posi-
lrons.
lnstall the camshafts, then install the oil seals with
the open side (spring) facing in. Make sure that the
keyways on the camshafts are facing up and the No.
1 piston is at TDC.
Clean and dry the cylinder head mating surfaces.
Apply liquid gasket (P/N 08718 - 0001 or 08718 -

lf the measurement is out of the specification.
adjust the preload using the tollowing procedures.
a. Loosen the tilt lever, and set the steering column
in the neutral position.
