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

Valve Guides
Replacement (cont'dl
5.
Working from the camshaft side, use the driver andan air hammer to drive the guide about 2 mm (O.l
in) towards the combustion chamber. This willknock off some of the carbon and make removaleasier. Hold the air hammer directly in line with thevalve guide to prevent damaging the driver.
CAUTION: Always wear satety goggles or a faceshield when driving valve guidss.
Turn the head over and drive the guide out towardthe camshaft side of the head.
li a valve guide won't move, drill it out with a 8.0mm (5/16 in) bit, then try again. Dritt guides onty inextreme cases; you could damage the cylinder headif the guide breaks.
Remove the new guide(s) from the freezer, one at atlme, as you need them.
