Custom Alt Pulley
Folks, I'm trying to use the standard Alt mounting bracket on the Alfa V6 with a little Denso Alternator.
 
Mounted
I need the collective thoughts on the material to make an extended pulley out of? I need to bring the grooved surface 35mm forward of it's
current position. Sorry for the poor drawing, I really can't do CAD!
 
Bad drawing
Steel, Alloy, titanium?
Also do we know of anyone who could make such an item?
Kind Regards Dan.
The less I worked, the more i liked it.

I've got almost exactly the same setup on mine, but I made a new alternator bracket to bring the alternator forwards. It seemed easier that
way. It also meant I could fine-tune the alternator's position by shimming it forwards with washers, though I only needed one in the end.
 
Could you do similar by mounting the alternator on the front of your bracket and adding a spacer?
I'd have thought that extending the pulley is going to increase the side load on the bearings, don't know if that would be a problem or
not.

Same here. Modified bracket to mount the small Denso on a Zetec. Much simpler (and cheaper).

Would go with modifying the bracket.
Extending the the pully will put too much strain on the front & rear bearings.

I love the fact that you're using a turn-buckle to adjust alternator tension. I saw this done on a racing mini recently and loved the simplicity
of it. NTS, I'll be doing that.
When all you have is a hammer, everything around you is a nail.

Not sure if that was aimed at Scutter or myself as we both seem to have done the same!
I couldn't find one short enough IIRC, but it was easy enough to make. Bit of hex bar, a RH tap and a LH tap to thread the holes in the end,
and two rod ends (one left hand, one right - with locknuts).
I think there might have been some advertised in the back of CCC this month as well...

A 35mm spacer on the alternator bracket would be easier wouldn't it? Its the way I'd go
Turnbuckles and rod ends can be bought cheap from mcgill motorsports for only a few quid
