Description
The Chelsea 489 Series Power Take-Off Assembly, part number 489GUAHX-A3GF or 489GUAHXA3GF, is a wire/cable mechanical shift PTO built around an integral one-piece cast iron 8-bolt housing that mounts directly to compatible manual transmissions from Eaton/Fuller, Volvo/Mack, and other manufacturers. The housing eliminates the need for an adapter plate, reducing potential leak paths compared to multi-piece designs. Output is through a 1-1/4″ round shaft with key. Series intermittent torque capacity is 201-300 lb-ft, with shaft power ratings of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, making service straightforward. Cross-references include 1450-489GUAHXA3GF and CHL489GUAHXA3GF.
