This date I discussed this noise problem with a Speed Queen service person at the factory and he suggests the problem is in the Heiix parts under the pulley due to wear .For this reason a new part was introduced and he said it was highly recommended that these new parts be installed. It consists of a new pulley with helix attached and a new helix mating part and a washer. These part numbers are 204486, 38008, and 27015.
