This unit replaced a Craftsman belt drive which had been installed for 7 years. The new unit looks exactly like the Crafsman. I am very unhappy with this one. It is very noisy...Might there be something I can look for to see if I might be able to quiet it down? The crafsman was so quiet you could hardly hear it, this one makes a whining noise when operating. I look forward to a reply, hopefully with a suggestion as to how to remedy the noise. Thank you, Lee Kaskisto
