A quick tap on wrench with hammer may break loose.
A small piece of wood to wedge belt and pulley will work.
Once you break it loose the game is over.

I had a hard time finding a wrench to fit the nut. I think it takes something like a 35mm. I bought a cheapy wrench 34mm (I think.... it was 1mm smaller) from the discount tool place (harbor freight) and ground it to fit. Then just bopped it with the mallet and it broke loose.

Hey,

What I've done in the past was built custom wrenches to fit the fan nut and the pulley bolts to hold it in place. A flat piece of metal works well, then just ad a handle in it!

Ok, so i searched earlier, have printed info i got off of somedata while i was at school so i can remove front cover and what nots to retrieve my key for my injection pump.
I didnt have a fan tool of my own and its a 36mm. I barrowed/rented one from Kragen wich seemed to flex and rounded the nut off a couple times as well as damaged the pulley nuts. I decided to try and smack it with a air hammer to hopefully break it loose, instead it cut a hole thru the nut ( i used the air hammer as close to the actual fan/clutch as i could as to not hurt the threads.) Now im at a loss.
The only thought i really have at the moment since i have to buy a new clutch for the fan as it is, is to weld a piece of round or square stock to both the pulley and to the nut.

Any thoughts?

im trying to remain calm with the trouble im haveing as well as working outside the 1200sqft shop thats being occupied for the last 2 months by a broken duramax.

Set of fan wrenches always make it easier...

Wrench turns to the right towards the driver side. (Loosen)

I think they would rather beat the he__ out of it with a mallet, cold chisel and what ever else is at hand.

Having the right tools makes all the difference in the world, in ease of repair and amount of time and frustration.

I didnt have the ability to make my own tool. brother took plasma and left me empty torch bottles. I also didnt have a place to go buy my own. I know this much. i will never rent a tool again.
I got to buy or make one later. I ended up getting it. Fawker was seized on. we used a hack saw and cut the bolt in half. later just because we jigged it up in the vise. took some more PB blaster and 5 min with air hammer to break free, when it did it ate the threads in the nut. only damage to idler threads were a small bur. i shoulda videod it.
I dont like half a--ing things or hack work either.

Actually he said he didnt have the tool and was looking for a way to get it off after it was screwed up, you know do with what you got "now". I was a 5 star service tech for Chrysler for over 5 years and got well over ten thousand dollars worth of hand tools, most were bought for certain jobs to shorten the time because we were flat rate. I know all about right tool for the job!
