scenario: pulling crankshaft pulley with chrysler tool & universal tool.

chrysler puller popped the first bit of distance

universal puller with medium length 3/8 extension pulled the pulley the rest of the way off. if you been around cars decently then you kinda can guess what my problem is.

hopefully nuff said cause i feel like a retard already. can i pull the extension out of the crank or is it new crank time?

You problem is, you didn't use a 1/4 extension.

Very Happy

Even a mild steel 5/16" round stock works once the pulley is partially off. Never try to start it without the hardened rod. I have pretzel'ed the round stock inside the crank, and almost had a situation, because it had nothing sticking out of the hole to grab. I learned to use the too short rod first...

So is it still stuck in there? Can you get it to turn to maybe "unthread"?

It may not be a total loss, if you can get the extension out. The bolt is mainly there as a secondary means of keeping the damper retained.

As long as the pulley/damper is still press fit, it isn't coming off on it's own.

You can try tapping the crank if the threads too mangled.

The only downside if the extension can't be removed, is getting the pulley back on, or if the crank timing gear needs removed, to get it reinstalled. At that point, it might be crank replacement time, or 2.4 swap time, depending on which method is more cost/time effective.

Pounding the damper back on is not the best thing for the thrust bearing. You may do more harm than good.

If it is still stuck, maybe use a large pair of vice grips, and smack them with a hammer like trying to loosen a bolt, to try to jar it loose.

I have a large carriage bolt I use to push against, and the first time it wasn't ground enough at the head and stuck in there. A large flat blade and a hammer got it to pop out.

I remember when this 'issue' used to come up occasionally, on 'The.Org'.
I haven't heard of anyone doing this in a long time. Sad But No.... A socket Extension, should never be used for crank pulley removal.

The 'proper' tool that Chrysler dealers use, from Miller Tool, is very affordable. ( Part number 6827A.)

Short of that -- Here is a really slick trick that someone on 'The.Org' came up with:
https://forums.neons.org/viewtopic.php?p=2919152#p2919152

That's for removing the pulley with a proper 5-ton puller.
I'm posting this 'for future reference'..... for the next time. Now, you'll need to get the socket extension out of there. Sad


For removing the extension .... I would try what Occasional said.
How long is the extension ?? Did you use a 3 in. extension, or a 6 in. extension ??
If the square end is still on the end for getting a ratchet on it... I would try 'unthreading' it from out of the crank snout carefully, with some help from a friend.

The extension is 6 inches, yeah the ratchet hole is still there but it won't unthread, ( even tried impact gun.....) I'm in Ohio at the moment cause I drive 18 wheelers but will give another 'whack" at it when I get a chance
