I have undone lots of viscous fans. I used to look after a fleet of Transit vans, the old smiley face ones that had a timing belt, the hammer and chisel worked every time and never damaged the fan, hub or nut. You just need to position it on the edge of the nut and give it a very sharp and hard strike. I promise it will come undone. I fitted a new viscous hub to my Rangie and it had done around 140,000 at the time and had spent a big chunk of it life on the Shetland isle before I had it so it was never far from the salty sea air. One sharp strike with a cold chisel and it was undone. Do not wedge the chisel in it needs to be the same width or just a few mm smaller than the depth of the nut as it needs to be a nice even blow across the depth of the nut. I hope that makes sense.

I had to beat the ****e out of mine for an hour to get it undone:mad: I was on the point of getting the hacksaw out when it finally shifted.

I am starting to wonder would it not be easier to just get a 2nd hand pulley as the 3 bolts look easier to remove and refit?

It's never that easy.. the pulley sits over the thread. you can undo the pulley bolts but you will still need to get the pulley over the thread.

Tut tut ! no short cuts !!

Have you tried smacking each nut face with a chisel..
and as a question.. you are going the right way are you ? on a petrol it's anti clock to undo. (i understand the diesel are the other way )

I will be trying the chisel method today if the weather and time is with me

Just get a chisel and get on with it!!!!!! Don't fanny about with it either, give it a very sure and hard strike, if you just titivate it the nut will become mauled and rounded and you will struggle, you will not hurt anything. Why do want to get it off? Is it to replace the hub or the water pump? If you are going to the trouble to take the hub off I would replace the water pump whilst it's all in bits they are cheap and easy to do and it's preventative maintenance.
 
Well it's off just a sore hand from hitting with a hammer do'h. It didn't look like it had moved but thought try the spanner again and it slipped off no probs. Do old fan off new second hand fan on problem still the same fan constantly running so either both fans the same or something else is wrong. I think buy a new viscous part and hope that's the problem.

The fans do run all the time, are you expecting it to stop? Even when the viscous is fecked they still run, just not fast enough.

That's what you were doing wrong, you should have been hitting the chisel not your hand:rolleyes:
