Wanted: Twin belt pulley for Ford V8 Generator

[Grant Hopkins]

If you could post a couple photos and some dimensions might help to determine the correct one.

Niels,
I have NOS pulleys in stock: 01W-10130C (3.5" diameter) or 01W-10130A (4.5" diameter). The smaller one is useful for better charging at low rpms. PM me for details. ... Brian

Hi
Here is a picture of the pulley, the number in it is 79-10130-0 and I measured it to 4" 11/16-ish outside diameter.
I will send you a mail Brian.
and thank you for all your replies.

Check if there is groove for the shaft key or if its a threaded one! Been there...

Part number looks like it ends in a C to me, which matches one of the pulleys listed in the manual as well as what Brian has in stock.

Thanks
Petr, I think it might be a threated one, now you mention it, I didnt see any shaft keyway.
Rob, yes could be a C instead, I forgot to take pictures of it when I had out.

I have measured my NOS pulleys: the part numbers come from the packaging; the part number is not stamped on the pulleys (whereas the early 79-10130-C pulley has the number clearly stamped). My 01W-10130-A pulley is nominally 4.5" but actually measures 4.75" outer diameter. My 01W-10130-C pulley is nominally a 3.5" pulley (but actually measures 3.6875" OD). Both have partially threaded bore 5/8"-18 tpi. They do not use a keyway. They appear to thread onto the armature and then a castelleated nut keeps it locked.
