Fan pulley

[Marcus Ling]

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.

Blast ! I'll have to find the correct one.

Thanks

You and Stephen need to swap.

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

Distance between us may be an issue !

That is a top pulley from a magneto engine.

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.  .  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.

Hi Stephen,

I can do a dimensioned CAD drawing if you want.
