The Chelsea 489 Series Power Take-Off Assembly, part number 489ZHDAX-V5XQ or 489ZHDAXV5XQ, mounts directly to an 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 found on older designs, reducing potential leak paths and installation time. Intermittent torque capacity for this series reaches 250 lb-ft (339 Nm), matching the 442 Series rating. Output is a 1-1/4" round shaft with keyway. Shift actuation is wire/cable mechanical. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the 442 Series, simplifying parts stocking and service. Sold by Pro Gear and Transmission.
