The Chelsea 489XSAHX-A3XK or 489XSAHXA3XK is an 8-bolt power take-off assembly from the Chelsea 489 Series, 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. Wire/cable mechanical shift comes standard, with an electric-over-air shift option available. Output is a 1-1/4" round shaft with key. The 489 Series delivers intermittent torque in the 201-300 lb-ft range and shaft power of 24 HP at 500 RPM or 48 HP at 1,000 RPM. Internal parts are common with the Chelsea 442 Series, simplifying parts inventory. Cross-references include 1450-489XSAHXA3XK, CHE-489XSAHX-A3XK, SD599, and TG8S-U6812-A1KX.
