The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-V3AZ or 489XLAHXV3AZ, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec units. The one-piece cast iron housing eliminates the adapter plate found on some designs, reducing potential leak paths. Shift is wire/cable mechanical. The 1-1/4" round output shaft with key delivers up to 250 lb-ft intermittent torque, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load-bearing capability. Internal parts are shared with the Chelsea 442 Series, simplifying service. Call us to confirm proper fit for your transmission application.
