IMPORTANT: To prevent severely reduced belt life,
be careful not to get any grease, oil or dirt on new or
removed timing belt, sprocket or tensioner. Do not
clean these parts. Any parts that are extremely dirty
or covered with oil or grease should be replaced. If
there is oil on any parts, check oil seals on front
case, oil pump and camshaft.
