Heat is the trick. I've used that method before to deal with all kinds of stuck stuff, including stubborn bolts, balancers and pulleys. If anyone has ever done a mid-60s Thompson/TRW power steering pump, you know what I mean.

Throw the balancer in a PREHEATED oven and cook it for 20 minutes at 200-220 degrees. The heat won't hurt it, just make sure the oven is preheated first. With regular pulleys, I go as high as 300-350 which usually results in it slipping right on without much force. But since the balancer has a rubber ring, it needs slightly lower temps to be safe.

The big problem is usually getting it from the oven to the vehicle without burning yourself or losing too much heat.

A torch can be used, but it doesn't allow you to heat it evenly and you also have no idea if you are overheating it.
