Is the pulley available by itself or do you have to buy it with the arm assembly?
Answer Hello Mike. You will need to purchase the idler pulley 8547174 as an assembly. Hope this helps.
i need to replace the pulley arm, but want to make sure of the alignment?
Answer Michael, Theres not a "true" alignment procedure. Once you mount the new idler arm pulley assembly, it will align properly to the motor pulley . You do want to manually rotate the drum a few revolutions(3 or 4) to align the belt on the drum and pulleys. Thanks and Good Luck
