Has anyone ever fooled around with the band change drum/pulleys with the
Collins 51J/R-388 series of receivers? It seems I've acquired a 51J-2 that the
band is way off. Unfortunately, I do have a manwell, but have been able to
figure out a few things by myself.

The way it's working now, I have applied spring tension on the band drum. It'll
go 180 degrees one way, then do an about face and go 180 degrees the other way.
It seems the way I received it, the pressure spring came loose and was riding
on the graticule!

Any information on how I can correctly align it will be greatly appreciated.
