After ordering these parts and another order for the idler wheel, I removed the motor/pump assembly from the washer (four bolts, two hose clamps, and motor electrical plug). Removed the idler tension spring. Inverted the assembly and removed the retaining clip and broken idler wheel from the tension arm (a pair of snap-ring pliers is helpful but not absolutely necessary). Replaced the spacer washers, idler wheel and retaining clip. Reinstalled the motor assembly and reattached the belt to the drum pulley. Reconnected the hoses and electric clip. Attached the idler tension spring to tension the belt. Test run washer. Works great.
