The motor's torque will tend to tip the tender either left or right, depending on the direction the armature is turning. I remotored a couple of brass CPR D-10s (Ten Wheelers) for a friend, placing a fairly large can motor in the tender of each. To eliminate the tilting, I cemented bearing blocks, made from a trimmed-down stack of Kadee #5 draught gear box covers, to the underside of the tender's frame, above each truck.
To accomplish the drive, I left the frame of the original open-frame motor in place, with the armature replaced by a straight shaft with the original worm on its lower end. The upper end extended beyond the rear of the motor frame, and was coupled to the new motor's shaft with a U-joint. After adding some extra weight to the boiler area, the pair were a smooth-running combination that pulled extremely well for their diminutive size.
