Exhaust Valvs Sesls:
Select the 7/8 in. diameter short compressor attach-
ment, and fasten the attachment to the No. 2 hole of
the lever arm with the speed pin supplied.
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 front position
slot on the lever as shown.

Tension Adjustment
CAUTION: lt*ays aa;j"t the timing bett rension withthe engine cold.
NOTE:
. The tensioner is spring loaded to apply tension to thebelt automatically after making the following adjustment.
. Always rotate the crankshaft counterclockwise whenviewed from the pulley side. Rotating it clockwisemay result in improper adjustment of the belt ten-sion.
. lnspect the timing belt before adjusting the belt ten-ston.
1.Remove the cylinder head cover.
. Refer to page 6,46 when installing.
Remove the upper cover (see page 6,'19).
Rotate the crankshaft five or six revolutions to setthe belt.

Removal
NOTE:
. Replace the timing belt at 105,000 miles (168.000 km)
according to the maintenance schedule (normal con-
ditions/severe conditions).
lf the vehicle is regularly driven in one or more of the
followlng conditions, replace the timing belt at 60.000
miles (U.S.A.) 100,000 km {Canada).
.In very high temperatures (over 110'F.43'C)
. In very low temperatures (under -20'F, -29"C)'
! Turn the crankshaft pulley so the No. 1 piston is at
top dead center (TDC) before removing the belt (see
page 6'21).
. Inspect the water pump before installing the timing
belt {see Page 10-14).
1. Remove the splash shield (see page 5-7).
2. Loosen the mounting bolt and lock bolt. then remove
the power steering (P/S) pump belt and pump
