The Chelsea 489GLAHX-A5XY or 489GLAHXA5XY is an 8-bolt Power Take-Off assembly from the Parker Chelsea 489 Series, designed to mount directly to manual transmissions with an 8-bolt aperture, including Eaton/Fuller, Volvo/Mack, and other compatible units. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths. This unit shifts via wire/cable mechanical actuation and features a 1-1/4" round output shaft with key. Intermittent torque for the 489 Series is rated 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. Call us to confirm proper fit for your application.
The Chelsea 489 Series fits a wide range of vocational applications including utility trucks, snow and ice removal equipment, fire and rescue vehicles, and dump trucks. Eleven internal speed ratios and multiple shift options are available across the 489 Series. The 489GLAHX-A5XY uses strong tapered bearings rather than needle bearings for greater load-bearing capability. Twenty-seven output options are available in the 489 Series, including Chelsea's 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. This part is also referenced as SP489GLAHX-A5XY in some catalog systems.
