Description
The Chelsea 489GHAHX-A3RY is a 489 Series Power Take-Off for manual transmissions, including Eaton Fuller, Mack, and Tremec gearboxes with an 8-bolt PTO mounting aperture. The one-piece cast iron housing bolts directly to the 8-bolt opening, eliminating the need for an adapter plate and reducing potential leak paths compared to two-piece designs. This unit uses tapered bearings for greater load-bearing capability and features a wire/cable mechanical shift configuration. Output is through a 1-1/4″ round shaft with key. The 489 Series is rated for intermittent torque of 201 to 300 lb-ft and delivers up to 48 HP at 1,000 RPM shaft power. A genuine Chelsea part from Pro Gear and Transmission.
