I removed my crankshaft pulley and harmonic balancer. I have a new balancer to install, however I can not get the pulley off the balancer.

Any suggestions on how to do it?

 

this is a relatively rare thing but if you ever need to do this here is how I accomplished it. I had the added advantage that the rubber between the weight and the balancer assembly had deteriorated and when i pulled them the outer weight came off. that means the balancer assembly was smaller in diameter than the pulley

The pulley was original equipment as was the balancer. the 2 were basically rusted together where the parts meet. I hit it with pb blaster several times and let it soak. Then I placed the assembly on a couple of 2 x 6's so the balancer was hanging by the back of the pulley which was supported by he 2 x 6 on each side. I placed a 36mm impact socket in the center and gave it a whack the balancer assembly popped out.
