The Chelsea 489GHITX-A3XY or 489GHITXA3XY is a 489 Series Power Take-Off assembly built for manual transmissions with an 8-bolt PTO mounting aperture, including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts directly to the transmission opening without an adapter plate, eliminating that potential leak path. This unit uses a wire/cable mechanical shift and delivers up to 250 lb-ft intermittent torque, consistent with the 489 Series rating. The 1-1/4" round output shaft with keyway is supported by tapered bearings for greater load capacity than needle-bearing designs. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to Chelsea's 442 Series, and the kit-style construction simplifies service. Call us to confirm proper fit for your transmission and application.
The Chelsea 489 Series PTO is suited for utility trucks, dump trucks and trailers, snow and ice removal equipment, and fire and rescue vehicles. The 489 Series shares internal components with the Chelsea 442 Series, giving technicians a familiar service experience across both platforms. Eleven internal speed ratios and a wide range of output configurations, including Chelsea's 360-degree rotatable flange with greaseable shaft, give this series versatility across vocational and municipal equipment applications.
