The Chelsea 489 Series Power Take-Off, part number 489GHAHX-A3XR or 489GHAHXA3XR, is a wire/cable mechanical-shift PTO built for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, cutting potential leak paths and reducing installation time. Intermittent torque capacity for the 489 Series runs 201-300 lb-ft, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is through a 1-1/4" round shaft with key. Strong tapered bearings replace needle bearings for greater load capacity. Compatible manual transmissions include Eaton Fuller, Mack, and Tremec. Call us to confirm proper fit for your application.

Additional Information
The Chelsea 489 Series shares internal components with the proven 442 Series, giving it the same 250 lb-ft torque capacity in a one-piece cast iron housing that eliminates the adapter plate found on earlier designs. Twenty-seven output configurations 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 multiple shift options make this series adaptable across a wide range of vocational applications including utility trucks, dump trucks, snow and ice removal equipment, and fire and rescue vehicles.
