Sandman,
The pump sits right on the motor shaft. Remove the two clips that hold the pump on, then slide it off the motor (see pictures below). If the pump has a minor water leak, it'll cause some rust on the motor shaft effectively "gluing" pump and motor together. If this is the case, you'll probably need to replace the
pump and clean the motor shaft.
Martcopolo, here is how to replace the belt, right from Amana manual:
Pump and belt removal
a. Remove three screws holding pump assembly to motor.
Reassembly of pump and belt
IMPORTANT: Install pump and belt together. Drive belt must be replaced with belt No.
37820 (special clutch-type belt) for proper washer operation.
a. Clean any corrosion or foreign material from motor shaft that will be contacting the double "D" slot in pump impeller.
b. Apply a thin film of No.
03637P Lubricant to end and sides of motor shaft. This lubricant helps keep moisture out of the hub area and retards corrosion.
c. Align pump impeller hub with motor shaft. Make sure belt encircles rear pump leg, carefully push pump onto motor shaft so three pump legs bottom out in the embosses on motor housing before screws are tightened.
d. Tighten three screws to 35 inch-pounds (4.0 N-m) maximum. DO NOT overtighten screws!
e. Reinstall motor and pump assembly into washer.
IMPORTANT: After installing motor and pump assembly in washer and all hoses have been reconnected, add at least a quart of water to washtub to lubricate pump seals. Running a pump without water will ruin the seals.
