How To Install Fan Clutch

[bersh]

I've got my new fan clutch sitting here, the top shroud removed, and I can't get the old fan clutch off and I'm stumped. These new clutches are different than the old ones in that there is just the one large nut that threads onto the shaft. The problem is that the pully it is attached to also spins, and I can't figure out a way to shim it so it won't move. I should add that I didn't order the cool tool, as at the time I didn't realize I needed it, so any tips on fudging it are what I'm looking for.

 

Any input or advice is appreciated.

 

Thanks,

impact. Some are able to break the nut with a very long wrench and a hammer. Others use a makeshift impact chisel type thingy.

Thanks for the reply. However, the problem isn't that I'm not able to get enough torque on the nut, it's that there is no way to hold the pully. The tool that they sell is a long lever with two pins that engage the holes in the pully to hold it while the nut is loosened/tightened. I called all of my local auto parts stores, and there isn't a tool available locally. I've put everything back together and I'll have to decide if I want to order the tool after Christmas, or just cave in and take the truck in to get it done.

Use a crescent wrench put it on the nut and hit it with a hammer. Im thinking that the nut is reversed threads, so when you think you tightening it you should actually be loosening it.

They make a spanner wrench that holds the pulley .......................sears sells them

Thanks - I tried that and the pully just spins with it. I think I'm hosed without the tool.

I'll check with Sears tomorrow, but the chances of my local store having one in stock are slim to none.

Make your own out of a piece of scrap metal. Drill two holes to imitate the pins and put some bolt with nuts in . I made a similar tool for my 97 Z71.
