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. Air shift comes standard. Output is an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. 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. Call us to confirm proper fit for your transmission and application.
