Default can this motor be slowed?

I have an electric motor driving the lube pump and table drive gear train on
my B&S horizontal mill. It replaces the original, probably 3 phase, motor
gone long before I got the mill. The motor is connected directly into the
gear train and pump through a flex coupling. The table drive is disconnected
w/ parts missing, but much of the gear train is in place (to drive the oil
pump)and makes quite a racket when the motor is running. It appears that
there is no easy way to bypass this gear train and still keep the oil
pumping function that oils the tableways and leadscrew, but I'm thinking if
I could slow things down I could still get adequate oil flow but less gear
noise. The motor has no starting capacitor.Does that mean I can use
something like a ceiling fan control to slow it down?
Obviously I could just change to a different motor, but I don't really know
what the best speed would be, but I'm thinking half speed might be OK. The
motor data plate has the following information on it that probably means
something to someone besides myself:

1/8 HP, 2.5 A, 1 phase, 110 v. 1725 RPM (all this I understand), Type SA,
Frame 147, Form DB.
BTW the Date is Dec. 22, 1925.

I used this motor because I had it on hand. Maybe the best way to go would
be to use a different motor? Although that means making up a new mounting
adapter plate .One of these surplus treadmill motors I see advertised? Other
ideas?

Thanks in advance for any ideas .
