Thread: 4BD1 Alternator

It's in the part numbers sticky


EDIT: sorry, I thought that was /part number/ and supplier. 12 months ago a place in sydney wanted 700 or so for one... So I went for a 70a.

The part number is also at the start of this thread

I just called AEA (Perth) and quoted JC's part number. They told me there are none in the whole of Australia and they have NFI when any more will be coming in...

Stumbled across these ones today from Patrolapart for $475 that might do the job:

Pulley would need to be changed for a single belt version, and the inside leg measurement is 80mm and center to center 175 (cf 85 and 170 respectively for the ALT160502) but cant see that being a show stopper.

Still quite a few $$$ but a lot less than the ~$800 price I got from AEA for the ALT160502 earlier this year, and still cheaper than the ebay "N" series one if the pulley could be got cheaply.
