Fan Clutch Removal

Fan Clutch Removal
I've done this once on my RR already, but it feels like its been glued to the water pump on my Discovery. I've tried the "whack it with a hammer" technique (worked like a charm on the Rangie), I've tried holding it with a wrench using the pully's bolts, wedging it, and using a fan clutch removal tool kits from both autozone and o'reilly's and none seem to fit/work. I've verified that I am turning it in the right direction and am almost at a point now were I might just remove the whole water pump and get it off that way... Very frustrated with this otherwise, straight forward procedure lol. Does anyone have any suggestions or ways they removed stubborn fan clutches from their rovers? I appreciate any advice, thanks in advance!

Mate,
This is not the easiest thing to do.
Here is how I do it:
Get a 5 pound hammer - a shortie hammer. I am not kidding.
Get a long crescent wrench.
Get a long screw driver.
Put on the c recent wrench to the fan nut.
The slop in the fitting must be dialed out by trial and error.
crescent wrench at 12 oclock position.
Now, the crescent wrench covers the pulley nuts.
Wedge the screw driver into those nuts to hold the pulley.
Left hand holding screw driver to stop the fan.
Right hand whacking the top of the crescent wrench toward your left hand with your right hand.
Or, looking at the pulley from the front of the truck - counter clockwise.
A few on target whacks - it will come off.
Don't whack the alternator pulley. This is possible with too short a crescent wrench.
Remember,
F=MA.
5 pound hammer. Sears sells one.
Good luck.

I had a simular problem with mine someone had put blue locktite on the fan nut.
I stuffed rags between the belt and the pullys to lock everything up, then put a little bit of heat from a propane touch on the nut, whack the wrench with a hammer and it lossened up. of course your fan belt has to be on, in order for the rags to work, needless to say,

I had a similar problem when attempting to remove mine a couple months ago, we tried everything mentioned above, and even pulled the waterpump, heated it up to the point where it was glowing red and used an air hammer, and still no luck,,, we just ended up cutting the fan clutch off, reused the fan, and got a new water pump & fan clutch... Good luck breaking it free

Sometimes "_ _ it happens" About 50% a job will run into a snafu.
This last week I had a number of such problems:
1. I bent the front yolk of my Disco 2's drive shaft trying to extract the u joint with a ball joint press.
2. I was helping my son in law replace the struts on his Acura MDX and we wound up trashing both front stabilizer bar links.
3. I spent all Saturday replacing the water pump, radiator and thermostat on my son's 2000 Prizm. After it was all done I noticed a "pin hole' leak in one of auto trans lines cooler outlets on the radiator. I had to do another JB Weld fix to seal it up.

OK - here is the failsafe way..
Get a strap clamp and put the strap clamp around the pulley.
Hold the pulley perfectly still.
then large crescent with mass. Don't use the thin whimpy fan wrench.
Get a 5 pound shortie hammer from Sears.
Whack it counter clockwise.
It will come off.
You have slippage when you are whacking it. That is why it is not coming off.
Or try drowsap's idea with rags under the belt and whack it.
Soak the nut in rust buster or whatever too.

Hummm
You could try a leather belt too and vice grips holding the belt firm to put tension on it.
Or get a leather belt and wrap it around the pulley. Then drill a hole whereas you could put a huge bar thru the middle. Then you pull the bar to one side - to the right and it tightens the belt and it holds it in place.
Brainstorming...
I would use the large crescent..
A large screw driver behind the crescent and wedged into the nuts holding the pulley on
and the long screw driver could be against a 2X4 on the right side which is on the floor like a pillar and coming up to meet the screw driver which is wedged into the pulley nuts behind the crescent wrench.
you just need to have this thing held very steady and secure.
