The Chelsea 221 Series Power Take-Off, part number 221XEDAX-W3XX or 221XEDAXW3XX, is a 6-bolt, wire/cable mechanical-shift PTO built for low-speed, heavy-duty applications including dump trucks, tow and recovery, and aerial equipment. Output is rated at 46-55 HP (31-40 kW), with intermittent torque up to 250 lb-ft (339 Nm) - check application pages for actual torque ratings for your specific installation. The 1-1/4" round output shaft with keyway pairs with a cast iron housing and tapered cone output bearings for strong load capacity. Compatible transmissions include Allison, Eaton/Fuller, Volvo/Mack, and Hino. A low-profile housing option and greaseable pump shafts are available within the series. Call us to confirm proper fit for your application.
The Chelsea 221 Series is designed for vocational and municipal markets including dump trucks, tow and recovery, and aerial equipment. The cast iron housing and tapered cone output bearings provide greater load-bearing capability compared to needle-bearing designs. Three internal speed ratios and multiple shift options are available across the series, along with a self-lube option for transmissions that have difficulty delivering lubrication to the PTO. The 360-degree rotatable flange is available as an output option within the series lineup. Part number 221XEDAX-W3XX is also referenced as SP221XEDAX-W3XX.
