The Chelsea 489 Series Power Take-Off Assembly, part number 489ZFDAX-C6RB or 489ZFDAXC6RB, 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 need for an adapter plate, reducing potential leak paths and installation time. This unit delivers intermittent torque in the 201-300 lb-ft range and output power of 46-55 HP. The wire/cable mechanical shift configuration pairs with a 1-1/4" round output shaft with key. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your transmission.
The Chelsea 489 Series is suited for utility trucks, dump truck and trailer, snow and ice removal, and fire and rescue applications. The kit-style design simplifies service and overhaul. For parts manual information, consult the 489 Series Parts List (HY25-2442-M1_US) or the Chelsea Service Manual (HY25-6489-M1/US).
