It must be designed that way on purpose. I’ve just had another look at mine and I would swear that The large bolt will fit through the hole on my pulley. Yes it’s a tight fit but the big bolt does not hold the pulley to the gear.
Betting a beer to anyone who has pictures of them apart and can prove the big bolt won’t fit through the hole.
So it’s a win win...

Edit-look at this Ebay listing and the images.

You can see where the surface of the pulley has been damaged by the undoing of the small bolts. There is no damage-no scrapes at all-around the large centre bolt, so it must be possible to remove the pulley without removing that bolt.

Later cars and all 4 cylinder models had the ability to separate the pulleys as you say, unfortunately for whatever the reason this is not the case with the inline 5 unless someone has done a modification on yours.

As you can see from pic it is one lump of metal

OK, fair enough-my pulley is certainly not the same as that one.

If Phil Payne swapped in a different one from a later model to make cambelt changes simpler I wouldn't be surprised-and if i were to be changing my cambelt in future I would get hold of one of the newer model pulleys to swap in to make any other cambelt changes easier too...

As i noted before, I am not at all certain I would be able to get the four bolts undone on mine anyway-they may round off or snap, thus needing the front to come apart for better access-in which case i'd have been better off doing that to begin with!

Something to worry about in 4 years time.
Beers all round...

Cheers!
