The Chelsea 489 Series Power Take-Off, part number 489XQAHX-P3GK or 489XQAHXP3GK, mounts directly to an 8-bolt transmission opening with a one-piece cast iron housing that eliminates the adapter plate and removes a potential leak path. The 489 Series carries an intermittent torque rating of 250 lb-ft (339 Nm) - the same torque capacity as the Chelsea 442 Series - and delivers shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. This unit is set up for wire/cable mechanical shift and features a 1-1/4" round output shaft with key. The 8-bolt housing is compatible with Eaton Fuller, Mack, and Tremec manual transmissions. Internal components are common to the 442 Series, and the kit-style design simplifies service. Call us to confirm proper fit for your application.
The Chelsea 489 Series is designed for vocational and municipal equipment, aerial applications, utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles. The 489 Series offers eleven internal speed ratios, twenty-seven output options including a 360-degree rotatable flange, and greaseable shaft to reduce pump shaft spline fretting and corrosion. The part number 489XQAHX-P3GK is also referenced as SP489XQAHX-P3GK.
