The Chelsea 489 Series Power Take-Off Assembly, part number 489ZLITX-A3XK or 489ZLITXA3XK, is a wire/cable mechanical shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the 8-bolt aperture on transmissions such as Eaton Fuller, Mack, and Tremec, eliminating the need for an adapter plate and reducing potential leak paths. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm), matching the 250 lb-ft capacity of the Chelsea 442 Series. Output power ranges from 46-55 HP (31-40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft includes a keyway. Internal components are shared with the 442 Series, keeping service parts widely available. Call us to confirm proper fit for your application.

The Chelsea 489 Series PTO is suited for aerial, vocational, and municipal equipment applications including utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. The 489 Series offers eleven internal speed ratios and twenty-seven output options, including Chelsea's 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Tapered bearings replace needle bearings for greater load-bearing capability. For service documentation, refer to the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US).
