The Chelsea 489 Series Power Take-Off, part number 489XAAHX-H3XD or 489XAAHXH3XD, is an 8-bolt PTO assembly designed for manual transmissions including Eaton Fuller, Volvo, and Mack. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift type is wire/cable mechanical. The output shaft is a 1-1/4" round with key. Intermittent torque capacity matches the 442 Series at 250 lb-ft (check application pages for your actual torque rating). Shaft power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 489 uses tapered bearings in place of needle bearings for greater load-bearing capability. Call us to confirm proper fit for your transmission and application.
