- Do not bend or twist the timing belt.
- Do not allow the toothed belt to come into contact with oil or water.
- Do not stretch the timing belt when installing or removing the camshaft sprocket bolt.
2. Check the timing belt for the following defects, as shown in the figure:
A) Check that the timing belt is correctly installed.
Check the timing belt cover gaskets for damage and correct installation
b) If the belt teeth are damaged or cracked, check that the camshaft and fluid pump are not jammed.
V) If there is significant wear on the non-working side of the belt, check for nicks on the side of the tensioner pulley.
G) If wear or damage is found on only one side of the belt, check the belt guide and pulley alignment.
d) If there is significant wear on the belt teeth, check the toothed belt cover for damage. If necessary, replace the timing belt.
3. Check up a tension roller and an intermediate pulley.
A) Check roller and pulley surfaces for smooth rotation. Replace if necessary.
4. Check up a tension roller spring.
Measure the free length of the spring (see picture), as well as the force required for a given deformation (stretch marks) springs ("installation" an effort).
Spring free length - 46.0 mm
If the free length is not correct, replace the tensioner pulley spring.
The force required to increase the length of the spring to the installation state (50.5 mm) - 32-37 N
If the length of the spring and/or "installation" force is out of specification, replace the spring.
