Viscous Fan
« on: 25 April 2013, 09:45:08 pm »
How does it come off a 200tdi?

Also is it really necessary to remove the power steering pump and relocate the alternator when using in a series?

You need to loosen it and spin it off somehow.

It's got a left hand thread and you need a nice flat spanner and something to stop the hub spinning - IIRC.

It might just come off tomorrow after a night soaked in plus gas and now I know which way to turn it. ::)

A few good "shock taps" with a hammer will no doubt help it.

There is a proper viscous fan spanner, with a broad and very flat head with a slight dog-legging on to it. They also come in two sizes, as I think the V8 hex is larger or smaller, whatever way around.

They aren't expensive for how usefull they are.

You might find a proper crows foot has too much offset   :-?

I've used the proper cranked spanner, borrowed from a local one-man band LR garage, and I've used a thin open ended spanner.

Both worked well, with just a couple of heavy taps with a hammer in the right direction   :thumbs:

Remove 4 small set screws holding on the fan to the viscous hub, push the fan back, lean on the drive belt spanner on swift shock with the hammer and off it came.

The way this week has been going I'm surprised the shaft didn't snap.
