so i cant get the crank hub off! i have tried every style of puller there is, no luck at all, one of my mechanics said he would rather buy a new motor right now, i mean i dont get it, we have every kind of tool there is it seems like in our shop and not a damn bit of luck, soo any suggestions ? lol..i just need to get my cam out, but cant get the timing chain cover off due to evil crank hub

 

I know when I did mine it was hard to get out... But then again I didnt try all kinds of pullers I used the Kent moore LT1 tools.. But make sure you arent binding or pulling against yourself

 

i might look into the tools, these pullers can shove it, its a 180,xxx mile cam, i think its done and iv never had this problem, lol

 

Just a normal universal puller is what I used, just make sure you put in a bolt smaller than the bolt that holds the crank hub on so the balancer has something to push against on the crank itself.

 

ya i tried that, thats why i say i just dont understand, its crazy. lol i think the guy i bought this car from was satan!..i really think so lol

 

i was about to reply this. i had one that was a pain to get off but it eventually gave and came off.

 

The worst that can happen is the bolt snapping off in the crank but you should still be able to get it out

 

it sucks all around...

 

It is the user not the puller trust me on this. You can use any puller, the hubs aren't on that tight. This is what you guys are doing wrong....you have the wrong bolt in place in the hub. The hub has a step on the inside, and most likely the puller is making contact with the step. You guys are whacking it with an impact wrench for all its worth and what you actually are doing is attempting to rip the hub apart.

Get a bolt like this:
1. Allen headed bolt about 4 inches long. Make sure it is narrow enough to fit inside of the crank snout without touching the threads too bad.
2. Put the pointed end of the puller into the recess in the allen head of the bolt, while the bolt is bottomed out in the crankshaft.
3. Hit it with the impact gun.
4. Watch it come flying off.

 

man people on this forum assume alot,i assure you its not a user problem! FF88 works in my shop! he is a smart guy and isnt trying to rip the damn thing off, well i hope not lol, we did have it in the right place, but like he said that SOB wont come off, a few guys from a mustang shop came over and tried also, nothing...

 

Man it's been a while but I'm pretty sure I used a socket extension in the bolt hole to push against and just a standard 3 jaw puller. I'm sure you have tried it but it's worth mentioning.

 

ya i have tried but i just went and looked at it and theres a build up of something on one side im not sure what but im thinking that might be it, and mention all you want man, thats what the forum is for..so thank you,

 

Hopefully it's not a build up of welding wire! Best of luck.

 

if it is i will find the guy that did and kick him square in the nuts! lol thanks man, and take care! your from Houston? everytime im there its one sick car after another..love that town!!

 

Did you try heating up the hub with a torch and then using the puller and something like a 4" caliper bolt?

 

I use a 6" 1/4" drive extension and a 3 jaw puller

 

That works just like an allen bolt. Great idea since extensions are easier to find in the garage than allen-head bolts.

To the OP...if the pointed part of the puller is anywhere inside of the hub when you guys are hitting it with the impact gun it is most likely the wrong setup.

Did you guys get the crank bolt out? You can't use the crank bolt to get the hub off. Some guys will simply loosen the crank bolt and use the puller on that. That is a no-no. The washer on the crank bolt sometimes gets hung up on the inside of the hub.

i had one onmy z28 that would not come loose like that and i was not pulling against the hub or binding on anything. i finally got pissed of breaking 2 harmonic balancer pullers and knock the crap out the hub on the sides and it came off like it was greased. mine had never benn off before and was just really stuck on. after i got it off it would go on and off like any other balancer and without having to use exessive force.

 

I'd try a couple heat cycles on the hub, maybe try pulling it hot. If it still won't budge try tapping on the sides to relieve the stress with a small metal hammer while its under tension (puller is tight).

Best of luck man!
