help, removing crankshaft pulley with 3 jaw puller

[danny7481]

im using a 3 jaw puller to remove the crankshaft pulley and ive turned about as hard as i can and the pulley still wont budge. let me make sure i am doing this right, i put the 3 jaws in the slotted holes and thread the rod in the bolt hole and tighted the rod. i noticed the rod was starting to thread in the bolt hole. are you suppose to have to tighten the puller THAT much? i honestly dont see how it suppose to remove the pulley anyway, i know the jaw are pulling it away but the rod is pushing it in, doesnt make sense to me. please help.

You have to get a longer crank bolt than the stock one and the puller pushes on it. I hope you didn't just set that rod in the hole where the bolt is supposed to go.

yeah i did, they guy at autozone didnt say anything about a longer crank bolt
where do you go get one? just anywhere?
damn, i hope i didnt mess up the bolt threads =(

It's a 12mmx1.75. I think about 150mm long should do it. They're pretty hard to find though.

Little trick, the cab mounting bolts off of most any gm pickup are the same size.

Are you using a 3 jaw puller, or the chrystler harmonic dampner puller thats made specifically for chrystler crank pulleys? If you're using just a plain old 3 jaw puller, which I've tried, you're going to run into problems because it's not the right tool for the job. On the other hand, the chrystler harmonic dampner puller worked for me in about 2 minutes.

i have a 2000 gmc sierra, where are the cab mounting bolts at?

They mount the cab to the frame.

ill definitly check that out, thanks.

A heavy duty 5 ton 3 jaw puller will do the trick if you have the correct crank insert or a long bolt that threads into the crank. I have used both the chrysler puller and a heavy 3 jaw puller. Haven't had any trouble removing the pulley. The trick it to tighten the puller down and then hit the end of it with a hammer to jar it and then it should come easy after that. Just getting it started can be the hard part. If you just keep cranking you will usually rip the threads out of the puller.

I hope that helps.

I know a guy who owns an auto shop and he let me borrow it. He said it was expensive as hell to buy, so I'd suggest trying to find an auto shop or somebody who owns one to let you use it. They might not even charge you if they're cool enough.

well you have a few option here, first you could go to Autozone (or any auto parts store) & rent the correct tool menttioned previously & that will work. or this is the method I used & posted to answer this question 51 times

I had the same problem & this is what worked for me,
now if i remember correctly i took a 1/4 drive 6 inch extention, insert that into the bolt hole, (it is made to hold that so you can turn the crank with a ratchet). place 3 jaw puller in place incerting the center into the 1/4 drive portion & crank away SLOWLY. it should pop. it took everything i could think of & nothing seemed to work for me either buit for some reason i went that rout & bang! 2 minutes later it was over.
Good luck.

thanks guys, i finally got it. was real easy once it was done correctly

look ive gone through 3 harmonic balancers, the first one i bent, the second i cut, the third just straight fell off. now the easiest way to get that balancer off is to rent/buy a 3 jaw slide hammer puller. some people call it an axel puller. u should be able to go to an advance auto parts or autozone and for like 90$ and just rent the thing. some people might tell u it will bend the balancer but ive used it several times and never had a problem. all u have to do is tighten it up to the balancer like a 3 jaw puller and pull on the hammer and keep tighting it to the balancer. it will pop right off.

If you use the chrystler specific harmonic dampner puller there's no risk of screwing up your pulley if you use it correctly, so no worries about bending or breaking anything. But I see you got it off already, so congrats .

Yeah. The right tool for the job. If Chrysler engineering wanted you to transmit the shock of extensive blows from a hammer down through the crankshaft into all those bearings, I'm sure they would have suggested using the slide hammer, wouldn't they?

It is a Chrysler Harmonic Dampner. You use the Chrysler Harmonic Dampner Puller to remove it safely without risk of damage to any other engine components. It's a $30 deposit at most Autozones, works flawlessly every time, and totally worth keeping. The deposit is equal to the price of the tool.

i discovered the slide hammer puller when i first got this car when i was 17 and honestly didnt even know there was a special puller for the 420a balancer until i read this thread, and i even work at advance auto parts, but i know we dont rent out a chrysler specific puller. but i guess if thats what works go with it.

 

[pazsion]

well, i have tried the 3 jaw puller, the chysler harmonic balancer remover is not for my 95 talon with a 420a... there is no harmonic balancer on this car, and no bolt holes for that to hook up to.

i used the 3 jaw puller and a 3/8?" socket, not the extention xD the puller went thru the socket, and stopped, leaveing more then enough puller to pull it off..

but the puller's bolt began to bend...

does the 6" extension sit out far enough, to keep most of the pullers bolt behind the puller?

If it keeps the puller from using up so much of it's bolt...then it won't bend as easily..and i should be able to get this thing off...

it's been sitting for a month now, waiting for someone else to come fix it because i can't get this pulley off..

This is odd. I have never had an issue wiggling the crank pully/harmonic dampner out of my 4g63 engines by hand.

If anything, I had issue getting the mfing crank pully bolt out. That thing is a real bastard sometimes.

That's why this is the 420a bolt-on tech section, the Chrysler crank pully is a PITA to get off. The freaking pully would rather break than come off sometimes.

@ Pazsion - I think I understand what you are doing, instead of getting the proper bolt for this you are using the stock one with a socket on the end of it for the puller to push against right? Just one quick question... Did you loosen the crankshaft pully bolt enough to where the socket doesn't touch the pully? If the socket is touching the pully you are pushing on the pully itself and not the bolt so it wont go anywhere. My advice... find the 150mm bolt talked about earlier in this thread. Then screw it in about 3/4 of an inch and go from there. Any other questions feel free to PM me. Good luck!
