Classic motorhome alternator pulley
OK, I have been digging at this for awhile and not gotten anywhere. Like many with 80s classic motorhomes and 454 engines, my alternator pulley squeaks. I know from records the alternator was replaced in 2011, and the squeak seems to be from the replacement pulley that comes with most alternators being close enough to work, but slightly different.
WayneG at one point mentioned this
"I also found out that when I changed an alternator a few years earlier, I should have saved the original pulley because the one that came with the new alternator did not have the proper dimensions. I had to find a old style pulley at an alternator shop, no more slippage with this belt and original pulley."
It is assumed that this slippage contributes to heat in the alternator and causes premature failure.
The correct belt is 11A1255 or 11A1195 (depending on length for emissions accessories)
I've been trying to locate the correct pulley online but I have not had luck finding the part number, nor do I have an "alternator shop" that I frequent. There might be a rebuild shop in my city up to the job but I know nothing about them and it might be a potshot.
Anyone know the correct part number? I would like to just get this pulley swapped out while I'm digging around installing the TBI system in the next couple weeks.
