The Chelsea 489 Series Power Take-Off 489KLAHX-A3XD or 489KLAHXA3XD is an 8-bolt air shift PTO designed to mount directly to most manual transmissions, including Eaton Fuller, Mack, and Tremec, without an adapter plate. The integral one-piece cast iron housing eliminates a potential leak path and delivers the same 250 lb-ft torque capacity as the Chelsea 442 Series. Tapered bearings replace needle bearings for greater load capacity. The 489 Series supports wire/cable mechanical shift, with intermittent torque rated at 201 to 300 lb-ft and output power of 46 to 55 HP. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. A genuine Chelsea part, available from Pro Gear and Transmission. Call us to confirm proper fit for your application.
