To Install a New Motor:

6.Make sure the motor insulation board is installed on the four threaded studs to the cavity wall.

7.Apply lubricant on both sides of the steamer motor seal and the inside hole. Refer to the Motor Assembly Chart.

8.Insert the steamer motor seal in the cutout of the insulator board.

9.To prepare motor for mounting, slide the oil slinger washer onto the shaft about ½" (12 mm) down the shaft.

IMPORTANT: This washer has two surfaces: A rubber surface and a phenolic surface. Make sure the phenolic surface is facing the motor.

10.Install the plate seal holder onto the motor shaft. Carefully slide the plate seal holder down the motor shaft until it engages the slinger washer. Continue moving the plate seal holder down the motor shaft until the plate comes to rest on the raised bosses of the motor casting.

11.Using this technique, the rubber side of the oil Slinger washer should be in contact with the plate holder and there should be a space of approximately 5/64" (2 mm) between the phenolic face of the washer and the motor.

12.Using four hex/slotted 6-32 screws, screw the motor mounting plate to the motor with each screw passing through corresponding holes in the plate seal holder.
