Quick question on motor bearings

I just found a late production Goldie that I'm fixing up for a friend. It's a poly-v drive with a 1 1/8hp A.O. Smith motor.
I may put new bearings in the motor and I might have the right size on hand, but don't want to take the motor apart & find out that I don't have them & then have to wait on an order.
Does someone out there know, offhand, what size the 1 1/8hp A O Smith takes? I'm sure this has come up before, and I did try to search the forums for the answer, but for whatever reason, I came up empty.
Thanks.

My $ would be on 17 x 40 x 12 mm twice.

That is what is in my Mark VII A O Smith motor. Also just about every other motor(both 3/4 and 1 1/8 hp) in a Mark 5. Late Goldies and Mark VIIs were both made by Magna American.

The Emerson motor is the 'odd ball' with one 5/8" id bearing(on the start switch end)IIRC.
