I have never seen a dryer motor that didn't have a belt tensioner, but that what this model is. I have no idea how to put the belt on, would someone please enlighten me?
Whirlpool Dryer Manual LEW0050PQ3, we have been unable to find ANYTHING...
Thank you

Looks likes there are slots on the motor mount. I'll give you three guesses and the first two don't count based on the diagram at Parts & Accessories | Shop & Find Lawn & Garden, Appliance Parts at Sears Parts Direct | SearsPartsDirect.com from Sears (http://www3.sears.com).
