Product Overview The XPARTCO EXP526 Dryer Belt and Idler Pulley Set combines two common dryer drive-system wear parts in one repair package: a drum drive belt and a complete idler pulley assembly with arm/bracket. The belt transfers motor power to the dryer drum, while the idler assembly maintains the proper belt tension needed for smooth drum rotation. Quick Answer EXP526 includes 2 pieces: one 661570V-style drum belt and one W10837240-style idler pulley assembly. The belt is approximately 93-1/2 inches long, 1/4 inch wide, with 4 ribs and 3 grooves.
