Can this generator be saved?

[<RobertW92@aol.com>]

I mentioned last week that I had a church with a B3 that was very hard to
start.  I pulled the generator last week and found 3 or 4 tone wheels jammed
against the pick up coil. I only assume that some one tried to adjust them at
one time.   Moving these back to there proper spot allowed the generator to
start easily  now.  But there was damage done from this.  One of the gears
driving the tone wheels has a bad wobble but still works for now. This is
caused by years of the clutch slipping on the shaft due the stuck wheel.
 There are two other notes that do not sound.  One of them #57 appears to
have an open pick up coil.  Another much higher note maybe #87 or so is also
dead but not open.  Will look at this one some more.    My question is should
I try and replace this generator now, repair it if possible, or add trek
modules to replace the bad notes?   Thanks
