The Chelsea 489 Series Power Take-Off, part number 489XQAHX-A4XD or 489XQAHXA4XD, is an 8-bolt mechanical (wire/cable) shift PTO designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing provides the same torque capacity as the 442 Series at 250 lb-ft intermittent (series range: 201-300 lb-ft), while tapered bearings replace needle bearings for improved load capacity. Shaft power ratings for the series are 24 HP at 500 RPM and 48 HP at 1,000 RPM, with output through a 1-1/4 inch round keyed shaft. Internal parts are common with the 442 Series, simplifying service.
