When going to change a drive belt on these models they are a nightmare, Usually the little shock absorber tensioner fails and you will need to change the whole tensioner. People go for the cheaper part so the cheapest part is a Gates 39214 Drive belt tesioner, however when you buy this cheap part you need to add the drive belt that they say suits the pulley @ $90.00 as the pulley is larger than the original.
