The Chelsea 489 Series Power Take-Off, part number 489XWAHX-A6XD or 489XWAHXA6XD, is an 8-bolt PTO assembly designed for manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec applications. 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. Output shaft is a 1-1/4" round with key. Shift is wire/cable mechanical. The 489 Series delivers the same intermittent torque capacity as the Chelsea 442 Series, with tapered bearings in place of needle bearings for greater load-bearing capability. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Call us to confirm proper fit for your transmission and application.
