Description
The Chelsea 489 Series Power Take-Off Assembly, part number 489ZRDAX-V5XD or 489ZRDAXV5XD, is an 8-bolt PTO engineered for manual transmissions including Eaton Fuller, Volvo, Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening without an adapter plate, eliminating a potential leak path while delivering the same 250 lb-ft intermittent torque capacity as the 442 Series. The 1-1/4″ round output shaft with keyway pairs with shaft power ratings of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Wire/cable mechanical shift operation and compatibility across Eaton Fuller, Volvo/Mack, and other transmission platforms make this a versatile fit for utility trucks, dump trucks, and vocational equipment. Internal components are common to the Chelsea 442 Series, simplifying parts stocking and service. Call us to confirm proper fit for your specific transmission and application.
