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

NOTE: lf the camshaft-to-holder oil clearances (see
page 6-36) are not within specification, the cylinder head
cannot be resurfaced.
lf the camshaft-to-holder oil clearances are within sDeci,
fications, check the cylinder head lor warpage.
lf warpage is less than 0.05 mm (0.002 in), cylin-
der head resurfacing is not required.
lf warpage is between 0.05 mm (0.002 in) and
0.2 mm {0.008 in), resurface the cylinder head.
Maximum resurface limit is 0,2 mm (0.008 in)
based on a height of 93 mm (3.66 in).
Measure along edges, and three ways across center.

Reconditioning
'1. Renew the valve seats in the cylinder head using a
valve seat cutter.
NOTE: lf the guides are worn (see page 6-39).
replace them (see page 6-41) belore cutting the
valve seats.

Carefully cut a 45'seat, removing only enough
material to ensure a smooth and concentric seat.
Bevel the upper edge of the seat with the 30. cutter
and the lower edge of the seat with the 60' cutter.
Check the width of the seat and adjust accordingly.
Make one more very light pass with the 45" cutter to
remove any possible burrs caused by the other cut-
Iers.
Valve Seat Width:
Standard (N€w):
Intake: 0.85 - 1.15 mm 10.033 - 0.045 in)
Exhaust: 1.25 - 1.55 mm {0.049 - 0.061 in}
Sorvice Limit:
Intake: 1.6 mm (0.063 inl
Exhausl: 2.0 mm (0.079 in)
Seat Width
5. After resurfacing the seat, inspect for even valve
seatingr Apply Prussian Blue compound to the
valve face, and insert the valve in its original loca-
tion in the head, then liit and snap it closed against
