help dismantling alternator
I'm wanting to crack open my first alternator. It's an FD alternator being swapped onto a S5 FC. It looks like I'm going to need to grind the lip down so that the nut can tighten on the pulley.
It just seems common sense to NOT grind the lip while the front case is on the alternator. Metal dust can't be good for an alternator....though I guess I could wrap the alternator in saran wrap or tape to keep the dust out.
My question is about the screws that hold the alternator case together. I tried removing the outer 4 bolt/screws and the casing didn't want to split open. Being my first work with an alternator I wasn't sure how much effort was safe to put on opening the case.
I'm looking at the FSM on dissassembly and I'm not sure how to go from here. There are 4 inner screws that from the FSM look like they hold a plate that holds a bearing in place. The plate then sits on the rotor. Do I need to remove all 8 screws/bolts...both the 4 outer and 4 inner in order to crack open the casing? Or do I simply need to apply more force once the outer 4 are removed? I was afraid to force things and break one of the alternator parts.

use a rubber mallet to gently tap all around it until it cracks open.
just be advised, the contact pins in the very back that must be held in when you put it all back together. this is near impossible unless you first drill a hold in the back casing of the alternator. then you can use some sort of flat tool to hold them down while replacing the center assembly. just make sure you don't break off the contact pins (...i did this once
) and then somehow cover the hole afterward.
