Yes, spanners for this purpose aren't terrible expensive. FYI, you don't need more than a ratchet wrench or breaker bar to change the belt. Just take the load off using the tensioner.

 

its reverse thread right?

 

No, Facing the fan you turn the nut to the left.

 

We used to use an air chisel with a pointed tip. Just put it on the left side of one of the flats on the nut and give a couple good hits, loosens right up. Done tons of them that way.

 

My guy at Sheriden performance told me to knock the wrench to the right, but I hear alot of people say to the left...so I have tried both for hours today and accomplished nothing except a bunch of knicks and dings everywhere. I build a tool to hold the pulley still its a rectangle of steel with two bolts through it..holds pulley still.

The only possible thing I can think of is that my adjustable wrench loosening after being hit is making some difference? I am totally 100% lost. I have been working on this for days.

 

Try a pipe wrench, that's what I used and it came right off.

 

Have you tried heat at all?

 

Have not tried heat, only an adjustable pipe wrench. I even used tie downs to pull the wrench tight while i held the pully holder tool with one hand and beat the wrench with a hammer on the other hand. Shoudl I use some PB Blaster? I am all out of ideas. I have the pulley holding still and the wrench on tight and not a thing.

 

PB would be a good start, maybe a little heat too. Just not too much, don't know if your fan clutch will build pressure if it gets too hot.

 

I will try PB, I have no means of getting any heat right now. Ill do a couple coats and give it a shot
