Hi Hyster Pros, would appreciate some advice on how to get stubborn wheels and brake drums off to work on the brakes!

I'm fixing up an old mid-70's Hyster E30AS that sat outside for "a few years".... for the detail see my earlier thread on this.

I have the forklift jacked up and blocked so the drive wheels are free to turn. I have removed all 8 wheel nuts and 10 drum nuts from each drive wheel. However, no amount of hammering/tugging/crowbar levering from behind the wheel/etc will get any of the wheels or drums to budge. Am I doing something wrong?

I'm thinking of lowering it and driving it around with only a few nuts turned on a few turns, to see if the weight of the forklift will break them free.

Note that I am not trying to get the rubber "tyre" off the steel rim. I realise that needs a large press.

Thoughts? Thanks!
