The Chelsea 489 Series Power Take-Off Assembly, part number 489XREVX-A3XK or 489XREVXA3XK, mounts directly to 8-bolt transmission openings on Eaton/Fuller, Volvo/Mack, and other compatible manual transmissions without an adapter plate. The one-piece cast iron housing delivers the same 250 lb-ft intermittent torque capacity as the Chelsea 442 Series. Shift is accomplished via wire/cable mechanical actuation. Output shaft is a 1-1/4" round with key. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace needle bearings for greater load-bearing capability. The 489 Series supports 27 output configurations including a 360-degree rotatable flange. Call us to confirm proper fit for your transmission and application.
