The Chelsea 489 Series Power Take-Off Assembly, part number 489XFITX-A5GB or 489XFITXA5GB, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate required on many other PTOs, cutting both mounting time and potential leak paths. This unit delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM, with output through a 1-1/4" round shaft. Internal parts are common to the Chelsea 442 Series, so replacement components are easy to source. The kit-style design simplifies field service. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 489 Series PTO is suited for aerial, vocational, and municipal equipment applications including utility trucks, snow and ice removal equipment, fire and rescue vehicles, and dump trucks and trailers. 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. Tapered bearings replace needle bearings for improved load-bearing capability. Eleven internal speed ratios and shift configurations are offered across the series. For service documentation, Parker publishes the 489 Series Parts List (HY25-2442-M1_US) and the Chelsea Service Manual (HY25-6489-M1/US).
