The Chelsea 489 Series Power Take-Off Assembly, part number 489GLAHX-V3XQ or 489GLAHXV3XQ, mounts directly to the 8-bolt PTO opening on manual transmissions including Eaton/Fuller, Volvo/Mack, and Tremec applications. The one-piece cast iron housing bolts straight to the transmission face, eliminating the need for an adapter plate and its associated leak path. Wire/cable mechanical shift actuates the unit, and the 1-1/4" round output shaft (with keyway) drives the hydraulic pump or auxiliary equipment. The 489 Series carries the same 250 lb-ft intermittent torque rating as the 442 Series, with shaft power of 24 HP at 500 RPM and 48 HP at 1000 RPM. Internal parts are common to the 442 Series, which simplifies shop inventory. Call us to confirm the correct ratio and output configuration for your specific transmission and pump combination.
