Hi everyone !
New brain scratch taking down A/C unit .. !!
Found a nice bypass pulley to replace my AC Compressor. Dorman part number 34189.
For some reason, its not the right part, im missing 1/4 inch depth at least even without using any washers.
That part doesn't even seem to have the back leg on the proper side i’d expect it to fit.
The bus is a 2002 e450 PSD 7.3, thomas built with an added AC Carrier unit i removed, and special needs equipments.
What am i missing here ??
Thanks for any clues or part number
Good luck to every one !
