Help Need to get the fan pulley off tomorrow

[moparguy55]

Dug into the front of the engine to tab the kdp today. Got the 3 fan pulley bracket bolts off. But the bastard bolt that is half behind the fan pulley is a no go. I even ground down two box end wrenchs and noway slipped once now the head of the bolt is rounded bad.

How can i get the fan pulley off there ? I thought maybe just the small bolts around the end of the pulley, but there is the big nut in front of it. Does the nut need to come off first? If so any idea what size wrench i need cause I'm sure we don't have one that big. I think if i can get the pulley off i could get off the rounded bolt with a socket and ratchet. Rad need to come out to get the fan and pulley off if the bracket stays? Need to get the truck out of the shop tomorrow.

Thanks

Yes, the big nut on the back side of the fan needs to come off. Since most of us don't have a wrench that size, there are different "procedures" we have used. First off, it's a left hand thread, meaning you push down on the drivers side to loosen it. Many people use a punch and hammer, tapping down on the edge. That didn't work for me, I used a vice-grip and a short 2X4. Clamp the vice-grip on, not too tight, place the end of the 2X4 against it, and whack it with a hammer. Remember down on the drivers side. If the belts are already off, someone will need to hold the fan, or jam it somehow.
When you put it back on, just get it snug, the engine torque will do the rest.

36 mm for the big nut.

Thanks Guys

I'm headed to good old canadian tire to see if they sell a 10mm 6 point box end wrench. I think that would catch it if they make such a wrench. The 2 i tried were the 10-12 point. If that does not work I'll try the vice grip and hammer method.

Edit: 0 for 2 on wrenchs. Didn't have a 6 point boxed 10mm or a 36mm
Tried with a punch and hammer. Didn't work out for me. Tried vice grips and a block, buy could find a way to block the fan with the vice grips in there. Had brother tighten the belt tensioner and still the pulley just slipped on the belt. Have to see about borrowing a 36mm wrench from the neighbor tomorrow. With a wrench there would be enough room to get a wrench on one of the little bolts on the end of the pulley. The real pi$$ off was when i went to put the 3 fan braket bolts back in the 2 on the left moved somehow that is invisible to the eye. Both bolts want to thread up in. Bracket moved yet the bastard 4th bolt wouldn't budge. I dunno why for a big engine like this they used 10mm bolts.
