The Chelsea 489 Series Power Take-Off Assembly, part number 489GLITX-A3GH or 489GLITXA3GH, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths versus a two-piece design. Intermittent torque capacity for this series is 201-300 lb-ft (301-400 Nm), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft with key accommodates a wide range of pump configurations. Internal parts are common to the Chelsea 442 Series, simplifying service and parts sourcing. Call us to confirm proper fit for your specific transmission and application.

The Chelsea 489 Series is suited for aerial equipment, vocational and municipal trucks, utility trucks, dump trucks, and snow and ice removal vehicles. The series offers 27 output options including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and multiple shift configurations make this a versatile unit across a range of manual transmission platforms. For service documentation, refer to the 489 Series Parts List (HY25-2442-M1_US) and Chelsea Service Manual (HY25-6489-M1/US).
