HINT: Cracks onthe rib side of a belt are considered ac-

ceptable. If the belt has chunks missing from the ribs, it

should be replaced.

(b) Using a belt tension gauge, check the drive belt

tension.

Belt tension gauge:

If necessary, adjust the drive belt tension.

HINT:

"New belt" refers to a belt which has been used less

than

minutes on a running engine.

"Used belt" refers to a belt which has been used on a

running engine for

minutes or more.

After replacing the drive belt, check that it fits properly

in the ribbed grooves, especially in the places difficult

to see.

After installing a new belt, run the engine for approx.

5 minutes and then recheck the tension.

base of the ground electrode. Donottouch the tip. Never

attempt to adjust the gap on a used plug.

INSPECT AIR FILTER

(a) Visually check that the air cleaner element is not ex-

cessively dirty, damaged or oily.

If necessary, replace the air cleaner element.
