BF Alternator design change?

[Rochefort]

Hi Guys,

 

I had to replace my alternator since I had powersteering line leak all through it... Huzzzah.

 

I ordered the same model number alternator, that is labelled as being for BF 6cyl onwards, yet the new one does not have a threaded hole for the back mounting bolt.

 

Did the FG's drop the back mount bolt/ Was the design changed?

 

Cant see how the backbolt does a lot, but better to be safe than sorry and ask the question :D

The Hayes manual has, what I'm assuming is either the BA or FG alternator since the bracket on mine looks nothing like that at the rear.

Is this going on a ba of bf/fg?

 

ba uses the same alternator as au2 where as bf/fg was changed to an "smart alternator" that uses signal wire from the ecu.

That's correct.  BA 2 pin.  BF FG 3 pin. 

 

Not  sure about mounting points. 

 

BA 110A.   BF FG.  130A

 

your image is BA

 

are you sure you didn't buy a V8 alt

That PIC is from the the Haynes Online Manual, was just using it as an example. I've got a BF MKII

 

The model number is exactly the same as the old one, except the new one doesn't have a threaded hole for the rear mount bolt.

I have BA BA2 BF BF2 . They all bolt on the rear same as the pic you posted. Images I have viewed shows the FG to be be the same.   Is it a genuine ford alternator?

Allegedly it is a genuine ford alternator. Has the ford label on the box, has the bitsamissin sticker on the alternator... just a non threaded hole.

Thread the hole or exchange it.

Bit of a thread mine here, Im in the process of buying new genuine pulley's, tensioner and drive belt and noticed the BF FG belt is different over the BA does anyone know the actual difference between the two? The Idler pulley, Tensioner share the same part number BA through till FG. I know the alternators have a different plug but I was under the impression they bolted up the same so not sure why the new belt? Only asking im still not sure what block ill be using (BA,BF,FG)

I know its an old thread, but I just went through the same thing. I biought an alternator for an FG from 'Ford' on ebay, and didn't fit it for a year. When I went to fit it, it had the hole at the back, but it wasn't threaded. I suspect its a manufacturing defect that got through. I cut a slot in a bolt and tapped the hole as I didn't have a tap handy. It worked fine but I am a bit annoyed I didn't pick it up straight after I bought it.
