The Chelsea 489 Series Power Take-Off, part number 489ZRITX-W3XD or 489ZRITXW3XD, is an 8-bolt mechanical 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 fits the 8-bolt transmission opening and delivers an intermittent torque rating of 201 to 300 lb-ft (301 to 400 Nm). Output power ranges from 46 to 55 HP (31 to 40 kW), with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 489 Series uses tapered bearings rather than needle bearings for increased load capacity. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
