ok well i am sur most of you saw the carnage i had a few weeks ago with both motor mounts failing on my cummins and it caused the motor to move forward and eat the rad so new rad and fan now i got to take off the old one i know it is a left hand thread and i have the big edit wrench to fit the nut but how do i keep the pully/berring assemble from spinning ???

Obviously you'll need something to hold it in place. Some have used vise grips on the pulley, but that can damage it, creating a rough spot for the belt to ride against. A pry bar, screwdriver or the like between the 10mm bolts on the pulley. Make a tool, or buy the fan clutch install kit from NAPA, you'll get the 36mm flat fan wrench and a serpentine pulley holder tool.

Or if you don't need to separate the fan from the clutch, you can simply remove the entire fan hub mount/fan and clutch assembly. 4 10mm bolts securing the mount to the block.

 

Take the big wrench and place it on the hub with the handle pointed straight up. then put a little pressure CW on it. (NOT enough to turn it.) Hit the upper end straight down with a BFH (big __UHMM_____ Hammer) while keeping CW pressure on it. It should come right off.

 

I took some flat iron and made a pulley holding device.

The way my tool works is I loosen the top-most FOUR bolts, a little more than the thickness of my tool.

Then, I slide the tool down and over those four bolts and snug them against the tool.

That pulley ain't going no where, while I take my home-made wrench and loosen the big nut.

The pulley holding tool is sort of a big "C" shape, with the four holes in the "C", and a LONG handle welded to the center of the "C".

I like it better than the fancy MAC-TOOL device that my friend uses, as mine CAN'T slip and chew up a pulley or belt.

 

this would be a good time to install a set of electric fans to free up some horsepower.

 

chisel and air hammer will work too, the type of force a hammer gives will knock it right off.

 

yep that is what i am trying i am going to go with three of them i belive two on the inside of the rad pulling and one on the out side of the ic pushing air threw the ic and then the rad so it should cool both hope it works as i can not find a replacement fan blade but hey mods are fun anyway lol


JC





oh ya thanks guys i thing i can use the big (short) wrench thingy that came in my kit from oriellys just have to drill some holes or slots for the bolts on the belt pully

 

We get them all the time from the Chrysler dealership for dirt cheap, something like eighteen bucks or so.

There is a Chrysler "improved" version that has thicker blades or something better about it.

The original ones were somewhat flimsy.

Also, the four-bolt pattern is the same on all Dodge fans, so you maybe can use one off a gas-burner.

I just replaced my fan blade with the new one and my dealer got it for me in a couple of days, you try the local dodge service department ?

As to the fan clutch I finally took a board member's advice put the belt back on used the breaker bar to put extra tension on the belt and gave the wrench on the big nut a whack clockwise it it broke free immediately.
Ended up making my own wrench from a hunk of 1/4" steel as the fan clutch kit I borrowed from the local parts store the 36mm was sloppy on the nut.

 

ok guys maybe i am stupid or somethign but i have just spent 4hr's trying to get this thing to break loose my hands are bloody from the mangled fan cutting me i have sliped and fell off the front of the truck more times than i can count i have tryied everything you guys have listed i broke the lil 10 mm blots trying to hold the pully with the big flat balde bent the pully trying to hold it with pressure bent the 10mm bolts "new ones" with the lil slide on tool i put the pully back on "new 10mm bolts" again put the old belt on and stood on the breaker bar in the tensoiner still just slips so i put on my brand new belt tighter fit same thing still slips any one else got a sure fire way to get this freaking thing off i am trying to turn the nut the right way CW as in looking at the front of the truck the top of the wrench would go to the right towards the battery/injection pump etc.. correct???




HELP !!!!

that is correct CW aka reverse threads to remove. You'll have to chisle it off no doubt!! I took a mini sledge to my 36mm combo wrench, but I didn't have the mouth around the nut, I used the end of the wrench on the edge of one of the corners of the nut and slammed down on the wrench with the mini/hand sledge.

 

The big nut is LEFT-HAND thread.

I believe that would be clock-wise to loosen.

Put some anti-sieze on the new one, so the next removal won't be so dramatic.

 

Check your local auto parts, most of them will loan you a fan clutch wrench or you can buy them fairly cheap.

I talked my local auto parts into getting the one you stick into an air chisel, it takes longer for me to pick it up than it does to do the job.

Even Harbor Freight with their disposable tools have them.

well it is off now after 8 hrs of working with it i finally took off the whole fan berring assemble and put it in the bench vise got out my 5/8ths socket and braker bar put it on the bolt on the back of the berring assmebly and i had to take the bolts out of the pully so i could put a big cresent wrench on the nut as i sprung out the wrench made to do this job with the bolt held by the breaker bad and the cresent wrench on the big fan nut i spent prolly 15 min beating on it untill it finaly broke loose i dont know who or what put that thing on there but holy crap it was tight i also used 2 and a half cans of pb blaster over the past two days on this thing


JC

 

oh ya some of you guys that have made your tools for this want to send me some pics of them so i can do the same ?? the parts store wrench is a piece of junk
