INSPECTION
1. INSPECT TIMING BELT
NOTICE:
Do not bend, twist or turn the timing belt inside out.
Do not allow the timing belt to come into contact with
oil, water or steam.
Do not utilize timing belt tension when installing or re-
moving the mount bolt of the camshaft timing pulley.
If there are any defects, as shown in the illustrations, check
these points:
(a) Premature parting
Check for proper installation.
Check the timing cover gasket for damage and
proper installation.
(b) If the belt teeth are cracked or damaged, check to see if
either camshaft is locked.
(c) If there is noticeable wear or cracks on the belt face,
check to see if there are nicks on the side of the idler
pulley lock and water pump.
(d) If there is wear or damage on only one side of the belt,
check the belt guide and the alignment of each pulley.
(e) If there is noticeable wear on the belt teeth, check timing
cover for damage and check gasket has been installed
correctly and for foreign material on the pulley teeth.
If necessary, replace the timing belt.
2. INSPECT IDLER PULLEYS
(a) Visually check the seal portion of the idler pulley for oil
leakage.
If leakage is found, replace the idler pulley.
(b) Check that the idler pulley turns smoothly.
If necessary, replace the idler pulley.

3. INSPECT TIMING BELT TENSIONER
(a) Visually check the seal portion of the tensioner for oil leak-
age.
HINT:
If there is only the faintest trace of oil on the seal on the push
rod side, the tensioner is all right.
If leakage is found, replace the tensioner.
(b) Hold the tensioner with both hands and push the push rod
strongly as shown to check that it doesn't move.
If the push rod moves, replace the tensioner.
NOTICE:
Never hold the tensioner push rod facing downward.
(c) Measure the protrusion of the push rod from the housing
end.
Protrusion: 10.0 ± 10.8 mm (0.394 ± 0.425 in.)
If the protrusion is not as specified, replace the tensioner.
