I thought that this was a Mag fan pulley, its 1 1/4 on the crown.

That is an early coil fan pulley mounted to a magneto fan pulley bracket.

You and Stephen need to swap.

BTW - the steel (?) section of your pulley itself is unusual, most likely an older repair.

If you fit that in conjunction with a coil bottom pulley the belt won’t fit.  You will need to source a coil top pulley.

You will also need to ensure you have a coil fan.

Hi Ruairidh 

I knew it was something to do with mag engines.  I had just this problem a few years back but couldn’t remember if changing the belt or the pulley solved it.  Big Grin.  Old age eh!

The pulley is bronze probably locally made years ago. There seem to be quite a few Bronze items locally, I have a steering box and also water outlets.

Thanks for the great photo Marcus. I can get all the information I think I need from this to turn a new one up.

You might need to check the distance between it's mounting and radiator core as one will be about 3/4" different in length dependent on the car or it's from a 3 sp or 4 sp crankcase.

I can do a dimensioned CAD drawing if you want.
