The Chelsea 489 Series Power Take-Off Assembly, part number 489XCITX-A3RB or 489XCITXA3RB, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing eliminates the adapter plate used on many competing designs, reducing potential leak paths and installation time. This unit uses a wire/cable mechanical shift and delivers up to 250 lb-ft intermittent torque, with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft supports keyed configurations. Strong tapered bearings replace needle bearings for improved load capacity. Internal components are common to the Chelsea 442 Series, and the kit-style design simplifies servicing. Call us to confirm proper fit for your application.
The Chelsea 489 Series is suited for utility trucks, dump trucks, snow and ice removal equipment, fire and rescue vehicles, and aerial applications. The 489 Series shares internal components with the Chelsea 442 Series, giving parts counters and technicians a familiar serviceability path. Eleven internal speed ratios and 27 output options, including a 360-degree rotatable flange, make this a versatile platform for a range of vocational and municipal equipment installations.
