The Chelsea 489 Series Power Take-Off, part number 489XSAHX-A3GF or 489XSAHXA3GF, is an 8-bolt PTO assembly engineered to mount directly to the 8-bolt opening on most manual transmissions, including Eaton Fuller, Volvo/Mack, and Tremec units. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths. Shift is wire/cable mechanical. The output shaft is a 1-1/4" round design, with a keyed option available. Series intermittent torque capacity is 201-300 lb-ft (301-400 Nm); shaft power runs 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 transmission and application.
The Chelsea 489 Series is suited for vocational and municipal equipment applications including utility trucks, dump trucks and trailers, snow and ice removal vehicles, and fire and rescue apparatus. The series offers eleven internal speed ratios and twenty-seven output options, including Chelsea's 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. Cross-references for this part include: 1450-489XSAHXA3GF, 1450489XSAHXA3GF, and CHL489XSAHXA3GF.
