The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-A3GB or 489XLAHXA3GB, mounts directly to an 8-bolt transmission opening on compatible manual transmissions including Eaton Fuller and Mack. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths. Shift type is wire/cable mechanical. The 1-1/4" round output shaft accepts a key. Intermittent torque rating for the 489 Series is 201-300 lb-ft (301-400 Nm); check application pages for actual torque ratings on your specific configuration. Shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts share commonality with the Chelsea 442 Series. Call us to confirm proper fit for your application.
The Chelsea 489 Series PTO is designed for aerial, vocational, and municipal equipment applications including utility trucks, snow and ice removal, dump truck and trailer, and fire and rescue. The kit-style design simplifies servicing in the field. Twenty-seven output options are available across the 489 Series, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Strong tapered bearings replace needle bearings for greater load-bearing capability. Eleven internal speed ratios and shift options are offered within the series.
