Re: 181 pulley responsible for belt rib cutting problem
I will have to say that Iam concerned and getting a bit confused. There was one comment of the idler bearing noise and that rapidly became a flood of problems and outright failures.
Idler issues were not even on the horizion and presently if has bloomed until some of our brothers off the road waiting for parts and or solutitions. It is as if this is kind of mass hysteria or contagious part failures? What do we have here?
Thight1 mentioned his pulley/belt problem similar to the one that I posted early last year. Now we have massive ( my thoughts ) failures with crank pulleys and the belt alignment being reported. How can this be that the sliding belt problems have hit so many SRT's at once, or all of a sudden. Isnt it odd that belts are jumping ALL OF A SUDDEN. How wide spread is this problem?? And how is it possible that it just was noticed?
The comments to cut the pulleys to align the belts is a concern as it seems to be a potential custom ( ONE WAY ) fit for each car / pulley. Doesnt this seem strange that all of a sudden the pulley / belts are the "NEWEST PROBLEM"??
How would it be possible that the pulleys are differing in length. ALthough I had a 0.090" error and Thight1 noted about 0.088".
I suggest that each pulley problem be closely checked out to see what is really causing the alignment errors. Question: IF the pulley is removed, can you see one or more wear marks on the pulley snout, from the front shaft oil seal. THis would indicate a shifting of the pulley on the crankshaft and maybe a clue to the cause.
Montana suggested using a somewhat coarse approach to insure the pulley is seated. I can tell you from personal experience with my let 181 , asp 178 and stock pulley that they must be fitted FULLY on to the crank for alignment. MY ASP would not align correctly (seat) and I had to work to draw it into the crank with my impact wrench. This is after I had swapped the stock and let some 20 or more times during testing.....and straightning of the crank after the earlier failure.
To get to a position of understanding, Iam going to measure the factory stock pulley so that we can have a real number to work with. By comparing our collective measurments we can have some basis for real comparison. Ill include photos for clarity so that we are on the same page.

MY issues from long ago, I thought . . .
Please note that the photos in the above post indicate that the pulley is sitting too far front (out ) from the engine.
