Timing belt replacement issue

Hello,

If it is not torqued or aligned properly or having a defective component can lead to a jumped tooth.
If the tension is not putting proper tension this can happen as well.

I have attached the complete replacement procedure for the timing belt as well as the tensioner below. Take a look and go through the steps to see if you might have overlooked something.

And always keep in mind that faulty components can many times play a critical part, rather than a procedure issue. But you first want to make sure all the steps are done properly.

Let me know if you have any questions.
Thank you.
