Mazda Repair Questions? Ask Mechanics for Answers ASAP
Hi my name is ***** ***** I will be happy to assist with this today.In some cases I may need more info to assist better.I apologize for any delay.
Did this issue here only occur after replacing the timing belt or was this an issue before and after the timing belt was replaced?
Let me know so we can continue,thanks Pete.
O.k., there is no balance shaft on this model here and it looks like you have already replaced the harmonic balancer with the same issue here.Since this occurred after replacing the timing belt and you know for sure that the marks are lined up properly on both cams and the crank the only other thing I see that could cause this is if there was an issue with the timing belt tensioner or the timing belt idler pulley.If any of these have bearings that are worn this can cause a vibration.I have always replaced the tensioner assembly when I replace the timing belt just due to the common failure of it.I would double check the cams are lined up properly as posted below.
These would be the only things I can see that would cause an issue like this here.
