The Chelsea 489 Series Power Take-Off assembly, part number 489XLITX-A3AF or 489XLITXA3AF, mounts directly to 8-bolt manual transmission openings on Eaton Fuller, Mack, Tremec, and compatible units without an adapter plate. The one-piece cast iron housing eliminates an adapter plate and its associated leak path. Output is through a 1-1/4" round shaft with key, and shift actuation is wire/cable mechanical. Intermittent torque capacity for the 489 Series is 201-300 lb-ft (301-400 Nm); for continuous-duty cycles, derate 30% per Chelsea application pages. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are common with the Chelsea 442 Series, simplifying parts stocking. Call us to confirm proper fit for your transmission.
The Chelsea 489 Series PTO is suited for vocational and municipal applications including utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue apparatus. Tapered bearings replace needle bearings found in some competing designs, improving load-bearing capability under demanding cycles. Twenty-seven output options are available across the 489 Series, including Chelsea's 360-degree rotatable flange with a greaseable shaft to reduce spline fretting and corrosion. Eleven internal speed ratios and shift configurations are offered within the series. An electric-over-air shift option is available for installations requiring remote or cab-controlled engagement.
