I hate to admit this but my fan came off with a pair of pump pliers. If yours is that stuck you may want to try some heat and/or penetrating oil. It sounds like the last person didn't use anti-sieze.

I had to take the bolts off the pully and it gave me enough room to get the mount with the fan ...all in one unit .
Now its out ... thats a work out , I will and try and use some penatrating oil on it over night .
Thanks guys .

I took out 3 of the pulley bolts and used a big adjustable wrench and I cut a "C" shape into a cheap air hammer bit to help it engage with the big adjustable - worked like a charm.

Remember it is a LEFT hand thread...pretend like you are tightening it. Mine was stubborn too...but I did the punch trick, and then the wrench...spun right off.

I did mine with the belt on...need smoething to hold the fan from spinning.

Smile Re:

I got the whole block off , I have the thing soaking over night , some how I'm going to have to lock the pully in place and try and wench this thing off .
If I use heat I would say I'm buying a new clutch ... the fan looks a little beat up ...like it ate a cat or two ...LOL

I might have to buy a clutch ... I hope not ... my limited buget is getting smaller , I have to get a new belt , upper and lower rad hose's ... so far ... if I'm in there I'm doing them now , the there all original .

Later guys
Greg

I take my fan off every fall and re-install in spring. Some years I can barely get it loose with a wrench set on the hub nut and pulley. Some years it comes off with water pump pliers. I use anti-seize, too.

There is a kit available that is a 36mm wrench (among other sizes) that hooks up to a swivel and plugs directly into your air chisel, for removing stubborn fan clutches with no damage. It is the greatest thing ever!!

Smile Back on the job today

the fan will not come off the block , I even have the snapon fan removing tool , I actually bent one of the little pully heads .
I tried light heat more towards the clutch it self ...I don't want to hurt the block bearing .
Looks like my only choice is to cut the clutck after the nut and try a big socket with impact gun

Any one with any other ideas

Greg

Never heard of this before, but doesn't mean it hasn't been a small problem.

Contact your local diesel performance shop. They may have one from a parted out engine.

Smile Re: fan

This is where I'm at , The bearing feels like it has some issuse's , it kind-a feels like a **** on a safe ... little clicks when you turn it ...it's bad .

I from what I can tell I just got the timing cover off ... very clean inside , Has any one ever seen this , some drilled a hole in the timing cover housing in the perfect spot to insert a taped bolt right in front of the pin .

I am going to still put the tab on and button the cover up .

Dose any one know if I will have to go to dodge for this bearing and block and dose it come as a complete unit ...?

Thanks guys

Greg

You can get a engine parts breakdown for your engine by registering here
https://qsol2.cummins.com/info/matrix.html

You will need your engine serial number from the plate on the timing gear case.
Buy the parts from Cummins, not the dealer
