The Chelsea 489 Series Power Take-Off, part number 489GQITX-V5RB or 489GQITXV5RB, is an 8-bolt PTO assembly designed 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, eliminating the need for an adapter plate and reducing potential leak paths. Output is through a 1-1/4" round shaft with keyway. Wire/cable mechanical shift is standard on this unit. The 489 Series shares internal parts with Chelsea's 442 Series and delivers an intermittent torque rating of 250 lb-ft (339 Nm); for continuous-duty torque, de-rate by 30% and consult the application pages for your specific installation. Shaft power is 24 HP at 500 RPM and 48 HP at 1000 RPM. Call us to confirm proper fit for your transmission.
