Looking for information on how to work on Seeburg "L" nickelodeon.
The machine is in playing condition but will not fully engage the
rewind gear.  It appears that some type of bellows on the right side
of the roll frame is not fully closing to push the drive gear up and
into the rewind gear.  Any suggestions would be very much appreciated.

Also, is there a need to completely remove the roll frame assembly in
order to tune this machine?

Thanks in advance,
