So my Magneti-Marelli alternator on my 300TDI died. I have a recently rebuilt one I grabbed from my V8 prior to my TDI swap which is one of the 120amp models.. so I'd like to use it.
Looking at the housings on these alternators they are an annoying 'mirror image' of each other!
My alternator(s) looks like this:
lol@Rovers North Price: $868.83 are they on crack?
So, I really need to swap the aluminum housing to make this work. I can't seem to find anything online that tells me how this alternator comes apart - the info is probably out there somewhere, but there's so many sights just trying to sell me alternators I gave up looking after a while. I have managed to find some great tutorials on how to disassemble some other series Magneti-Marelli alternators though - just not mine.
I've replaced diode packs before, but not opened/removed the case. The diode swap involved de-soldering, so while it's a PITA I'll do it if needed.
So, do I have to de-solder the diode assembly to take the thing completely apart (thinking yes)?
Is the bearing pressed-in to the front-half of the housing? I hope not...
Just so I don't break something in the process, what are the basics to R&R the clamshell housing?
I read somewhere that you could swap in the V8 alternator into a 300TDI by just grinding off the backside mounting ear - but I don't like the instability aspect of just mounting it with two bolts from the front only... that would put a lot of torqe load on the front bolts wouldn't it?
On a side note... since these alternators look identical, what's different that makes one a 120amp and another a factory amperage which is much lower? Is it simply more windings?
