Hello, my belt has been slipping from the harmonic pulley, Now I have had the car for 4 years and replaced the belts a few times, I changed the belt tensioner and that did not fix the slipping.

Im wondering if the original owner but the pulley on backward what do you think?

From your picture, thank you very much for it, the crank pulley definately looks farther out than the rest. To your knowledge, has it ever been off for any reason? I tried to bring up an exploded view of the lower pulley, but what I got wasn, t very clear. I'm try to determine if the pulley itself is seperate from the balancer. Looks like there are 3 bolts around the crank center bolt. I can't tell if these bolts hold the pulley "and" the sensor wheel, or just the wheel. You will have to look. Please advise.

I know I tried to tighten it more and "bang it" but it was solid.
The car is parked till I get time to look at it this weekend.

But can that pully be on backwoars? I might just pull it off or try to find a another Montana and look under the hood. Lol
a few more original pics attached.

I have just had issues with my belt slipping, and the Harmonic Balancer looks about 1/2"out of alignment (same as yours).

What was the end result?

Thanks for any info.
