Is it possible to swap pulleys from a JX (early type water pump with V-belt pulley) with the ribbed-type on an AAZ? Or should I just get another pump?

Reason I ask is that I have a water pump from an AAZ, and the pump I used in my JX-to-AAZ conversion is knackered. Looks like the pulleys are sort of integral to the pump itself ... maybe put on with a left-hand thread ... has anyone done this swap?

All the pulleys that I have removed have been held on with 3 bolts - are you meaning something else?
I put my JX/CS pulley on a 1Y pump - you just need to make sure that the pumps are for the same direction of rotation as some run backwards.

Yeah, got the three Allen-headed bolts ok, but it's the collar that the pulley bolts to that I really meant (should have made that clearer). I suppose this is effectively the shaft of the pump itself.

I started dismantling the JX pump to see if I'd be able to release the collar from the pump shaft but when the bolts holding the housing front on started snapping I gave up and ordered a new pump - fifty quid I'd rather not have spent, tbh, but at least there's the peace of mind of a new part that I'm getting for my money.

Old V-belt wasn't in great condition either, so may as well replace that too.
