Ken,
In its "normal" state the vacuum/air valve (I think) will apply vacuum
to both sides of the vacuum piston. The only way to "cycle" the vacuum
would be to remove the cover on the vacuum/air valve (on the side of
the servo body) and manually move it. You will probably need
a new gasket afterwards, although if you're lucky you might be able to
re-use the old one. BTW, you can't buy that gasket alone--at least I've
never seen one--and rebuild kits run about $80.
I've just rebuilt two of these, and I can't think of any way to test one on
the bench. You just have to hope the rebuilder knew what she was doing.
