Description
The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-A4XK or 489XLAHXA4XK, mounts directly to an 8-bolt transmission opening on compatible Eaton/Fuller, Volvo/Mack, and other manual transmissions without an adapter plate. The one-piece cast iron housing matches the 442 Series torque capacity, rated at 201-300 lb-ft intermittent. Output is a 1-1/4″ round shaft with key, and shift is wire/cable mechanical. Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM, with output power in the 46-55 HP range. Strong tapered bearings handle radial and axial loads, and kit-style construction simplifies field service. Call us to confirm proper fit for your application.
