Alternator Belt Inspection and Adjustment
NOTE: When using a new belt, first adjust the deflectionor tension to the values for the new belt, then readjustthe deflection or tension to the values for the used beltafter running engine for five minutes.
Deflection methodi
Apply a force of 98 N (10 kgt,22lbll, and measure thedeflection between the alternator and crankshaft pulley.
Detlection:
Used Belt:8.5 - 11.5 mm (0.33 - 0.45 inlNew Beft: 5.5 - 8.0 mm 10.22 - 0.31 inl

Valve Seals
Replacement (cylinder head removal not required)
The procedure shown below applies when using the in-
car valve spring compressor (Snap-on YA8845 with
YA8845-2A 7/8" auachment). Use approved eye protec-
tion.
1. Turn the crankshaft so that the No. 1 and the No. 4
pistons are at top dead center (TDC).
2. Remove the cylinder head cover.
3. Remove the distributor.
4. Loosen and disconnect the timing belt from the
camshaft pulleys.
5. Remove the camshaft holder bolts. then remove the
camshaft holders, the camshafts and rocker arms.
lntake Valve Seals
6. Using the 6 mm bolts supplied with the tool, mount
the two uprights to the cylinder head at the end
camshaft holders. The uprights fit as shown.
7. Insert the cross shaft through the top hole of the
two uprights,
at.
9.
Select the 7/8 in. diameter long compressor attach-
ment, and fasten the attachment to the front hole of
the lever arm with the speed pin supplied.
Position the piston at TDC, and insen 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.
10. Put shop towels over the oil passages to prevent
the valve keepers from falling into the cylinder
head.
Position the lever arm under the cross shaft so the
lever is perpendicular to the shaft and the compres-
sor attachment rests on top of the retainer for the
spring being compressed. Use the rear position slot
on the lever as shown,

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.

Timing Belt
Removal
Replace the timing belt at 105,000 miles (168,000 km)
according to the maintenance schedule {normal condi-
tions/severe conditions). lf the vehicle is regularly driven
in either of the following conditions, replace the timing
belt at 60,000 miles (U.S.A.l 100.000 km (Canada).
- ln very high temperatures (over 110'F, 43"C).- In very low temperatures (under -20"F. -29"C).
Turn the crankshaft pu\ley so the No. 1 piston is at
top dead center (TDC).
Remove the guard bar and splash shield (see page
5-7 ).
Loosen the mounting bolt and lock bolt. then remove
the power steering (P/S) pump belt.
