The belt appeared about 2 inches too small and didn't seem to fit. I searched the web and found a number of  appliance repair professionals who explained how to install the belt. They explained the belt is designed to stretch enough to fit and remain tight.

SOLUTION: Wear gloves. Here is how I installed the belt. I placed the belt  over the motor pulley and then guided the belt on to the drum pulley with one hand while rotating the drum pulley with the other hand.  About two thirds of the way around I was absolutely sure the belt was too small and wouldn't fit but followed the appliance repair professionals advice and kept going until the belt was completely on the drum pulley.  Once completely on the drum pulley, I noticed the belt wasn't centered on the motor shaft.  I rotated the drum and moved the belt to the center of the motor shaft.  The washer works great now.
