Description
The Chelsea 489 Series Power Take-Off, part number 489XFAHX-A3AF or 489XFAHXA3AF, is an 8-bolt PTO assembly designed for manual transmissions including Eaton Fuller, Mack, and Tremec. 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. This unit features a wire/cable mechanical shift type and a 1-1/4″ round output shaft. Series intermittent torque capacity matches the 442 Series at 250 lb-ft (339 Nm). Shaft power output is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, simplifying parts stocking. Cross-references include S-17718 and 2000XBA011RB.
