AUTOMATIC BELT TENSION ADJUSTER
1. Visually check the oil seals for leaks, and rod ends for abnormal wear or scratches. If necessary, replace the automatic belt tension adjuster
assembly.
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 Nm (30 kgf, 66 ft. lbs.) 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 Nm (30 kgf, 66 ft. lbs.), check it using the following procedures:
4. Slowly press the adjuster rod down to the end surface of the cylinder. Repeat this operation two to three times.
5. With the adjuster rod moved all the way up, apply a pressure of 294 Nm (30 kgf, 66 ft. lbs.) to it. Check the adjuster rod stiffness.
6. If the adjuster rod is not stiff and moves down, replace the automatic belt tension adjuster assembly with a new one.
CAUTION: 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.
^
Press the adjuster rod gradually taking more than three minutes.
^
Do not allow press pressure to exceed 9,807 Nm (1,000 kgf, 2,205 ft. lbs.).
^
Press the adjuster rod as far as the end surface of cylinder. Do not press the adjuster rod into cylinder. Doing so may damage the
cylinder.
7. Measure the amount of rod protrusion beyond the body. If it is not within specifications, replace with a new one.
Amount of rod protrusion H: ................................................................................................................................ 5.7 ± 0.5 mm (0.224 ± 0.020 inch)
BELT TENSION PULLEY
1. Check the mating surfaces of timing belt and contact point of adjuster rod for abnormal wear or scratches. Replace the automatic belt tension
adjuster assembly if faulty.
2. Check the belt tension pulley for smooth rotation. Replace if noise or excessive play occurs.
3. Check the belt tension pulley for grease leakage.
BELT IDLER
1. Check the belt idler for smooth rotation. Replace if noise or excessive play occurs.
2. Check the outer contacting surfaces of idler pulley for abnormal wear and scratches.
3. Check the belt idler for grease leakage.
