Feckin Viscous Fan - Part 2.

James you are correct, there isnt enough clearance to slice the nut off, the thread goes beyond the point where the hub starts. And battering it with the punch isnt working now cos the whole lot is spinning.

I have since found that the nut and thread were the easy bits, its the bearing shaft inside thats the bugger.

I have got all the plumbing and rad out tonight to give me more room.

Tempted to see if I can grind/cut a section of the fan hub off to give access for the big grinder to slice the shaft off, but it seems to be ally, so wary of grinding that, dont fancy exploding discs

Still think the new ( 2nd hand case) is the easiest option, assumin, I can get the flippin crankshaft bolt and pulley off.

Mr Noisy, I also think you are right, in that the bearing is probably fooked now, it seems to be a bit wobblier than before lol.

Thanks for all the ideas chaps - keep em coming.

you can hit it even though it will spin by hitting nut flat central,to stretch it not knock it round ,it does work ive had quite a few to do
 
Thank you ppeps, for you help and suggestions.

I got the Timing case off tonight, seems that fan aint never gonna shift.

Got a new ( 2nd hand ) one on way.
 
If you can find a bit of metal plate say 1ft to 18" long, 2 or 3" wide and perhaps 2 to mm thick.

Drill a hole towards one end sufficiently large to accommodate one of the pulley bolts - 8mm maybe - then you could fasten this 'lever' onto the pulley so you have something to pull against when you try to remove the fan.

I usually just slot a bar in between the bolt heads and pulley shaft.

Tbh I'm amazed this has managed to cause so much grief, dare I say poor technique in the early stages which quickly lead to obliteration was the main problem here?
 
I just put a my BIG adjustable spanner on the nut and "wack" with my BIG hammer before removing the belt. A bit different on a Tdi then? :)

The vac hose is just just over the pully.

I has to replace the water pump (the bearing failed) the only time a spanner has been used on the engine other than a plug and oil change. Nice and clean inside, even supprised me :D

Bluddy big alternator in the way! On my V engine the dizzy USED :D :D to have the vacuum unit at around the 9pm mark, which was close to the water pump as it is, tbh you could only get so much advance because of the water pump, then youd have to move your plug leads around the cap!

Lovely motor youve got there, genuine case of good servicing prolonging the life of an engine that is absolutely do or die dependant on regular service.

Regards :)
