The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-V5AF or 489XFAHXV5AF, is an 8-bolt mounted PTO designed for manual transmissions including Eaton/Fuller and Volvo/Mack applications. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. This unit uses a wire/cable mechanical shift and delivers up to 48 HP at 1,000 RPM through a 1-1/4" round output shaft with key. The 489 Series shares internal parts with the Chelsea 442 Series and features strong tapered bearings for greater load-bearing capability. Call us to confirm proper fit for your specific transmission and application.
The Chelsea 489 Series is suited for aerial, vocational, and municipal equipment as well as utility trucks, snow and ice removal vehicles, fire and rescue apparatus, and dump trucks and trailers. Twenty-seven output options are available across the series, including a 360-degree rotatable flange with greaseable shaft to reduce pump shaft spline fretting and corrosion. Eleven internal speed ratios and shift configurations make this a versatile PTO for a wide range of manual transmission installations. An electric-over-air shift option is also available within the 489 Series. The kit-style design simplifies servicing in the field.
