The Chelsea 489KHAHX-A3XK or 489KHAHXA3XK is an 8-bolt Power Take-Off from Chelsea's 489 Series, designed for manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening without an adapter plate, reducing potential leak paths and installation time. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Output is through a 1-1/4-inch round keyed shaft. Internal parts are common to the Chelsea 442 Series, and strong tapered bearings replace needle bearings for improved load capacity. Call us to confirm proper fit for your application.
