Guess what! the hub flange has a piece broken out of one of it's threaded bolt hole's and with not enough thread left to hold the bolt, one of the four that fastens the pulley to the hub's flange.
Having brought a couple of new fan hubs, a while ago from maxi drive, I set forth to swap out the damaged hub and install one of the new spares.
Spent a whole afternoon making a really schmick puller out of a threaded portion of a old viscous fan coupling, when screwed onto the threaded boss for the viscous hub, it worked well enough to move the hub partly up the shaft and then all the threaded boss broke off the hub.
