Attention:
- Do not bend, twist or turn the belt inside out.
- Do not allow the belt to come into contact with oil, water or steam.
- When installing or removing the camshaft pulley mounting bolt, the belt must not be tensioned.
If any of the defects shown in the figures are found, perform the following checks:
a) In case of premature rupture:
- check that the belt is installed correctly.
- check the belt cover gasket for damage and correct installation.
b) If the belt teeth are cracked or damaged, check the camshaft fastening.
c) If there are cracks or noticeable signs of wear on the back of the belt, check the surface of the tension roller and the water pump pulley.
d) If wear or damage is observed on only one side of the belt, check the belt guide and the alignment of the pulleys.
d) If there is noticeable wear on the belt teeth, check the belt cover for damage, and then check that the gasket is installed correctly. Check for foreign material on the pulley teeth.
Replace the belt if necessary.
2. Check the smooth rotation of the tension roller. If necessary, replace the tension roller.
3. (L Series) Checking the tension spring.
a) Measure the length of the tension spring.
In a free state - 44.4 - 45.4 mm If the length of the spring in a free state does not correspond to the specified limits, then replace the tension spring.
b) Measure the force required to stretch the spring to a given length.
Tensile strength - 5.42 - 5.98 kg (at a length of 52.1 mm)
If the tension force does not correspond to the specified values, replace the tension spring.
4. (Engine 1KZ-T) Checking the tensioner.
a) Check for oil leaks from the tensioner.
Note: A small amount of leakage through the tensioner plunger seal is allowed.
b) Press the tensioner plunger onto a hard surface (workbench or wall): The plunger should not move. If the plunger moves, replace the tensioner.
c) Measure the plunger protrusion from the housing. If the protrusion is outside the permissible limits, replace the tensioner.
Plunger protrusion: 9.0-9.8 mm
