So, with my chinese ST down (I believe it is the windings with a short) I have been gifted a 2013 Mecc Alte alternator off of another gen set.
It's gotta run at 3600rpm, so I need to put a different pulley on there. Amazingly, I think it needs a 4" with my flywheel, which I have.
BUT, I can't get the other one off. It seems as though it's put on the opposite way the ST ones go on, with bolts on the *inside*. I also don't know how to get the 'key' out off the shaft.
I've emailed the company (in Italy) a week ago, and haven't heard anything. No luck doing internet searches either. Anyone have ideas?
I have turned the bolts (out) which, once they are fully out and pushing against the cast body) may be pushing the pulley off, but I have worked that as hard as I can and have started to round off the bolt heads. There must be a trick, but I don't know what it is. I've also tried heating up the pulley a bit with a blow torch, but hard to say if I did enough, or if that was a wise move.
