Lindsay Books reprints a bunch of old lathe
manuals. The one that would probably be 
best for you is South Bend's "How to Run a
Lathe". The manuals usually run about $8.

Lindsay is at

The backgear you have is engaged by the
eccentric mounting of the backgear shaft.
By rotating what looks like one end of the
shaft the gears will mesh. Your are most
likely missing the lever that turns the 
eccentric. Keep in mind that the bullgear,
the big gear on the spindle, must be unpinned
for the backgear mechanism to opperate. If
the bullgear isn't free to rotate the backgear
mechanism is locked solid and can't rotate.

This is handy for removing a stuck chuck but
plays hell with belts and gear teeth under

Check out Lindsay.
