Default Removing crank hub from crank pulley?

Hey guys, my crank hub is stuck to my crank pulley and I need to separate them. How do I do this considering the pulley is off of the crank?before anyone asks I got my old motor back from a shop and that is how it was. Do I need to bolt it back onto a crank and then pull the pulley off?

Any 3-jaw puller will work.

How would I secure it so I can pull it off? My motor isn't together at the moment so I can't just bolt it up to the crank

it doesn't need to be secured to the crank to separate the balancer from the hub. A 3 jaw puller as mention earlier would be able to pull on the pulley with the jaws while pushing on the center of the hub successfully separating the two. If you must I am sure you could secure either the balancer or the hub in a vice during this process.

There are specific pullers at parts stores that cost maybe $12 and will pull it off quickly. They come with 3 bolts that spline into the 3 holes that are offset from the bolts that hold it on the hub.

^correct. other wise just use the claw style and the big middle bolt of the puller will push againts the middle of the hub popping off the pully. doesnt need to be on the engine. A vice will make the job easier though holding it.

I bought one of the 3 Jaw pullers and never could get it to work right. Maybe mine was just extra stubborn.

If it is on the 96, it should have 3 small holes (noted in the lower left of this diagram) in the pulley web where you can use a normal balancer puller to separate the two. It does not have to be on the crank, just have a way to hold onto it.
