Bosch 16 volt 90 amp question

[camper]

I am hoping some on can advice me on this .I have seen a bosch 16 volt 90 amp alternator part number ALTERNATOR 068 903 029 K for sale.It appears to have the same case type as the bosch alternator fitted to my 1.6td which is a bosch 12 volt 50 amp .To use this alternator with its 90 amp output for 12 volt is it a case of changing the brush& regulater for a 12volt type.

hi camper, i just googled the pn, it came up as 90amp 12volt [241euros] perhaps the 16volt rating is only for a second or so,the site said its for a passat/variant.
nice and sunny here.

I tried to fit a 90 amp alternator to my 89 1,6TD, it was not a straight swap.

I needed different mounting brackets & fasteners.

My standard alternator has three mounting points, one of which utilises a squared headed bolt which mates with a socket on the alternator.

The 90 amp one had a different set up-

YMMV

Thanks for the replies guys.My standard alternator has three mounting points also i will ask the seller for more picts.On the wiki it discribes an upgrade for a 90amp bosch looking to go that route if possible.

I've mentioned this many times on here but there are several 90amp alternators fitted to VW and Audi models that are indentical except for the pulley - which yu can swap
