Hi,
I have a 6 cylinder crank-shaft pulley that fits a 9.5mm/10mm alternator belt just fine. The top of the belt sits top of the pulley and all force appears to be on the side of the belt.

My A127 alternator pulley appears to be gripping the belt much further into the pulley as it snapped this morning and the bottom is as shinny as a new penny. It seems the small pulley is for a 13mm belt.

Are all A127 alternators made for a 13mm belt or could it be my 75A one is made for a 13mm belt?
If I buy a lower amperage alternator the pulley will be for a 9.5mm belt?

I can change either pulley to suit. Do the CP/CR crank pulleys come in 9.5 and 13mm options? do the A127's come the same?

Confused,
Iain.

I suspect that the A127 will come with a variety of pulleys which will be vehicle specific rather than native to the A127 (which is used on many vehicles).  The trick will be finding the right donor vehicle.  You may even find you can swap the pulley from an old ACR series as they are all Lucas.  There is a fair bit of interchangeablity.

I run a big Bosch unit from a Mk6 escort and that comes with a poly-vee pulley.  However, the pulley from a small Bosch alternator used on Citroen Saxos bolts right up and suits the Triumph belt.

Hi Nick,
I wrongly assumed that all A127 V pulleys were the same. If you wanted a higher power unit you need the poly-vee belt.

So I need to ask the question next time I buy the A127 and get the biggest amperage for a reliable transfer over a 10mm belt. I have a 25mm2 cable from B+ to battery, so output amps are not a problem. I need the amps to charge my leisure battery quickly as I plan on installing a lot more loads before winter comes.

Thanks,
Iain.

PS. After belt snapped in Colne, I still managed to drive an extra 15 miles to work and fitted a new 10mm belt at lunch time. 12.1 v on battery and started first time.
