Fan Clutch Removal

[Captj]

Purchased new water pump pulley to help alleviate the belt wobble. Only problem: how do I get the fan off?? Short of purchasing the Ford/navistar special removal tools for one time use.

Someone said that Napa rents them. I have not checked yet, but I'll need to soon.

Some auto parts stores have free rental on the tool, And some people have gotten it off by hitting the nut with a chisel and hammer. Never tried that myself.

Hammer and chisel will really bugger up the nut.

I was lucky enough to have a regular open end wrench the right size and "shocked" it loose by hitting the wrench with a hammer. Personally I would recommend buying the right tools to do the job.

The fan nut is 1 7/8 ". It is reverse thread. A chain wrench on the pully works fine. Be carefully not to hit the radiator as youy remove the fan and clutch.

Yeah, it is Lefthand threads, instead of righthand threads.
I made a wrench outa 2 1/2 x 1/4 flatbar & torch one time. Got thru & rattlecanned it silver, painted SnapOn on it, hung it on the shop wall. Stayed there about 4 years. Needed a piece of flatbar about that size oneday, cut it up & used it. Very next week I needed my "SnapOn" wrench.....

I recently changed my fan clutch and had considerable trouble finding the right two tool set. The tools are hard to do without. My local AutoZone only had the smaller size for loan which will not work on the 7.3L. I was able to find the right size at a local store called Winchester Auto, but they are probably local to the San Jose, CA, area. They charged $7/day rent, not free but better than over $100 to purchase. If you call around, you might find some place that rents them. Just make sure they have the right set because the set for a smaller engine is more common and won't work for us. Good luck.

I didn't intend to recommend an inferior method of removal, just passing on information I've read here. In thinking back, however, I think people that used that method were doing it to replace the water pump, so bearings would not be an issue. But it still has to be reinstalled.

In this situation, since he is only replacing the pulley, the proper tool should be used.

I agree about using the right tool, which is why I bought one when my water pump went south. And was glad I did when that water pump started leaking a few months later.

Guys, thanks for the helpful replies.
Okiegringo- installed your idler pulley but belt continues to wobble hence the water pulley removal question.

[Chris90F250Diesel4x4]

I have the tools for this as loaner tools from Oreilly since my fan clutch went bad. Excuse my ignorance but where does the pulley wrench go on?
