Model 551 CC Snow Blower Drive Belt Problem
I just burned through my second drive belt on my model 551 snow blower. The first belt lasted 7 years, then snapped last week (it looked old). I bought a CC brand replacement belt and it snapped in 1 hour. While installing the new belt this morning I made sure that everything was moving freely in case the first failure was triggered by something getting bound up. Everything moved freely and the new belt (other than being a little stiff -as I would expect a brand new belt to be) went on fine. However, after only about an hour this morning, bang! It snapped in half and was separating in two other spots. This particular application requires the belt to twist 90* in a span of about 9" on either side the blower housing as the belt transistions from the blower drive pulley onto two idler pulleys as it twists 90* again again as it transitions on up to the main drive pulley on the front of the motor. That seems pretty severe for a stiff belt like this, but the last belt lasted a long time with no trouble traveling that route. I wonder if the new belt was TOO stiff.
Anyone got any ideas? Is there a superior brand of belt I should be using or did I do something wrong?
Also, anyone ever hear of a steel or kevlar reinforced drive belt?
