The Chelsea 489 Series Power Take-Off Assembly, part number 489GQAHX-A3XY or 489GQAHXA3XY, mounts directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec, no adapter plate needed. The one-piece cast iron housing eliminates a common leak path and houses tapered bearings for greater load capacity than needle-bearing designs. The wire/cable mechanical shift mechanism drives a 1-1/4" round output shaft (with key), rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque capacity for the 489 Series runs 201-300 lb-ft; check application pages for the actual rating for your configuration. Internal parts are common with the Chelsea 442 Series.
