The Chelsea 489 Series Power Take-Off, part number 489XSAHX-P3XD or 489XSAHXP3XD, is an 8-bolt PTO assembly designed for manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing mounts directly to the 8-bolt transmission opening, eliminating the adapter plate and reducing potential leak paths. This unit shifts via wire/cable mechanical actuation and carries an intermittent torque rating of 250 lb-ft (339 Nm) for the series. The 1-1/4" round output shaft (with key option noted in the part suffix) delivers up to 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series. The 489 suffix "P" indicates pressure lubrication. Call us to confirm proper fit for your transmission application.
