hey guys... 1999 5.3....just came in from the shop...I am installing efans on my truck..but I cant seem to get the dam cllutch off the fan...do you know what I referring too? The plastic fan is bolted to a clutch, which swivels on the pulley. There is a large nut kidna thing between the clutch and the pulley..and I still cant get the dam thing offf???? Anybody know how to remove this thing?

 

Get a long pipe wrench and place it on the nut, and whack it really hard counter clockwise. Try tapping on the nut with a hammer and it may help breaking it loose.

 

Yeah, get a wrench on the large nut. You might need something to hold the pulley from turning. I used a strap wrench.

 

comes off with the fan. The big nut in the back is what you need to loosen. Spray a little lube on the nut. Put a pipe wrench on it and hit it with a hammer. It should come off.

We hit it with a hammer with a big cresent wrench,,,,but the pulley jsut spins and spins...errrrrrrrrrrrrrr

 

Wow, I just put a big cresent on it and gave it a quick hit with a hammer ( belt still on to hold pulley) and it came loose. Then I just turned mine off by hand....

 

I put a big crescent wrench on it and punched it...sure it made my knuckles bleed but it did get if off...

 

You could try having somebody apply pressure to the belt to make it tighter and hopefully help hold the pulley in place while you chisel. I used a chain wrench and a piece of old belt wrapped around the pulley to hold the pulley in place while I whacked the wrench on the nut with a hammer. (the old belt around the pulley is to keep the chain wrench from marring the pulley).
