The Chelsea 489 Series Power Take-Off, part number 489ZUDAX-V5XK or 489ZUDAXV5XK, is an 8-bolt PTO designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec applications. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths compared to two-piece designs. This unit shifts via wire/cable mechanical actuation and delivers up to 250 lb-ft of intermittent torque, matching the torque capacity of the Chelsea 442 Series. The 1-1/4" round output shaft supports a keyed configuration. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the 442 Series, simplifying service and parts sourcing. Call us to confirm proper fit for your transmission and application.
