Steven H Harleysville , PA June 15, 2015 Appliance: Amana Top Loading Washer NA8631 Amana Washer Na8631: My pump belt broke. How to replace Screw (12-14 X 1/2). This was a very easy fix. Two screws to get the front off of the washer. Removed one side of the tensioner spring. Loosened two screws for the motor and two screws for the pump. I decided to replace the agitate belt even though it wasn't broken.. So, I removed that belt from the pulleys and the removed the broken belt. then just reversed the process to install the belts. it toke me less than 30 minutes and my washer was back in service. 3 People found this story helpful Do-It-Yourself Rating: Repair Time Estimate: 15-30 minutes
