Shocking with a hammer is a must if seized. I have the removal tools and I had to straighten it in the vice at least twice with the force I was putting through. Suddenly it just went. Plusgas might help too. Marvellous stuff that.
 
Well I bent my viscous fan spanner today after my pulley holder finally turned up so it looks like I am buying one of those draper spanners if my neighbors father doesn't have one I can borrow. Might still get one as I like having tools as its better than paying a garage
 
I used to have an open ended spanner with a forged striking pad for removing V/fans. I lent it to someone who decided it was happier living with him, the turd. I got a sign for the garage that read " The guy who lends tools isn't in till tomorrow".
 
Not a million miles from you

and

I made a custom tool as I couldn't free the fan

spare bit of metal, from an old washing machine and other bit from a gate hinge
job done

Even with the locking tool and a good quality spanner mine would not shift, hammer and chisel was the only way I got it to move, threads were rusted solid.

Told you. As useful as tits on a Mars bar. :D:D:D
 
Not on the same basis you wanted to borrow his you rum bugger. Come to think about it it may only be 150 AMP so no good to you. :p:D:D

Whisky bugger please, and can you ask Sue if I can have my cake tins back please, just in case the Manc muncher turns up.:D:D:D
 
pity it was after I had bought one lol

Might try the chisel technique tomorrow whats the best way to go about this just wedge the and hit to the side and hope???

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.

a flat headed large drift and hitting the center of each flat in turn will loosen it if done enough times ,without damage
