The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-V5XK or 489XLAHXV5XK, is an 8-bolt PTO designed for manual transmissions including Eaton/Fuller, Volvo/Mack, and compatible units. The integral 8-bolt housing eliminates the need for an adapter plate, reducing potential leak paths. Shift is accomplished via air shift actuation. The output is an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft, and the unit delivers up to 250 lb-ft intermittent torque and output power in the 46-55 HP range. At 1,000 RPM, shaft power reaches 48 HP. Internal parts are common to the Chelsea 442 Series, making service and parts sourcing straightforward. Available in a no-pressure-lube configuration.
