This O-Ring drive belt is a direct replacement for models 270, 275, 280 and 290 Norwalk juicers.
This V drive belt is a direct replacement for the hydraulic pump drive belt on Norwalk juicers. Made specifically for the Norwalk models 235 through the early 270 models. The drive surface of the bely has an actual "V" shape that fits down into the V pulley. These belts can become worn and can harden over time. This condition will allow the belt to slip or break.
