The Chelsea 489 Series Power Take-Off Assembly, part number 489GHAHX-S3SQ or 489GHAHXS3SQ, mounts directly to 8-bolt transmission openings on Eaton Fuller, Mack, Tremec, and other compatible manual transmissions. The one-piece cast iron housing eliminates the need for an adapter plate, reducing potential leak paths and installation time. This unit uses air shift with a PTO/dump pump combo valve and delivers up to 46-55 HP output power, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1000 RPM. The output is an SAE B 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Internal parts share commonality with the Chelsea 442 Series, and the kit-style design simplifies field servicing.
