How do I replace a Star BM recoil spring?

[Tuckahoe]

How do I change the recoil spring on a Star BM? I've got a new spring from Wolf but I can't figure out how to get the old spring off the guide rod. It's a captive spring and I've never messed with one of these before.

Tuckahoe,
Push the spring sleeve toward the rear and grip the exposed shank in your vise (soft jaws), then unscrew the head from the shaft. I use an adjustable wrench but pliers will do if you are carefull not to booger it up. Be careful the thing is under tension, wear your safety glasses. Replace the old spring with the new and screw it back together.

Thanks for the help Sam. I got it changed, needed 3 hands to do it even with the vice but it's done.
