The Chelsea 489 Series Power Take-Off Assembly, part number 489ZQDAX-V5RB or 489ZQDAXV5RB, mounts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton/Fuller, Volvo/Mack, and others. The one-piece cast iron housing eliminates the adapter plate found on older designs, reducing both installation time and potential leak paths. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); continuous-duty applications require a 30% torque de-rate. Shaft power output reaches 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft accepts a keyed configuration. Shift actuation is wire/cable mechanical. Internal components share commonality with the Chelsea 442 Series. Call us to confirm proper fit for your transmission and application.
