2. AUTOMATIC BELT TENSION ADJUST-
ER
1) Visually check the oil seals for leaks, and rod
ends for abnormal wear or scratches. If necessary,
replace the automatic belt tension adjuster assem-
bly.
NOTE:
Slight traces of oil at rod's oil seal does not indicate
a problem.
2) Check that the adjuster rod does not move when
a pressure of 294 N (30 kgf, 66 lb) is applied to it.
This is to check adjuster rod stiffness.
3) If the adjuster rod is not stiff and moves freely
when applying 294 N (30 kgf, 66 lb), check it using
the following procedures:
(1) Slowly press the adjuster rod down to the
end surface of the cylinder. Repeat this motion 2
or 3 times.
(2) With the adjuster rod moved all the way up,
apply a pressure of 294 N (30 kgf, 66 lb) to it.
Check the adjuster rod stiffness.
(3) If the adjuster rod is not stiff and moves
down, replace the automatic belt tension adjust-
er assembly with a new one.
NOTE:
• Always use a vertical type pressing tool to move
the adjuster rod down.
• Do not use a lateral type vise.
• Push the adjuster rod vertically.
