Default Can't get the hub off the crank

Im using a three claw puller with a long bolt out the center of the crank through the hub and it still wont move! Does anyone have any idea what i should do next?

Get a rubber mallet and hit the backside of the hub. Then roatate it a bit and Hit it agian, keep doint that while loosing the bolts. It took me about 20 minutes of that to get my hub off.

what speed said.... you can also use a block of wood if you want to get a little more "stank" on it...... they are a pain in the ***......

sometimes some heat might help... you could use a smoke wrench for a while and then let the hub cool and it might help......

Or you could do like shoebox said and stick a 6" 1/4" drive extension in there and use a hub puller to pull it off.

I used a bolt that went down in good and a hub puller and then an impact gun and a socket and had it off in 15 secs.

I also use a hub/harmonic balancer puller you can buy at almost any parts store. One trick to remember though is to thread the bolt through the hub a couple turns so the puller is pushing on the bolt rather than the hub. If you don't do that, then you'll be pushing it and pulling it at the same time and it's not gonna go anywhere.

Yeah i put a longer, smaller bolt in the hole to push off of. The popping kind of caught me off guard.

lol, if the engine is still in the car then it would be hard to use a slide hammer, i did use a hub puller and a impact for mine, but the slide hammer is more fun

Yeah, it jumps right off that crank when it finally gives. It'll go on easy - just use dampner installer. It is the proper tool for the job.
