The Chelsea 489 Series Power Take-Off Assembly, part number 489XHITX-A5RA or 489XHITXA5RA, is an 8-bolt mount PTO designed for most manual transmissions including Eaton Fuller, Volvo, Mack, and Tremec. The one-piece cast iron housing bolts directly to the 8-bolt transmission opening, eliminating the need for an adapter plate and reducing potential leak paths. Shift is wire/cable mechanical, with output through a 1-1/4" round shaft (with key option). The 489 Series delivers 24 HP at 500 RPM and 48 HP at 1,000 RPM. Intermittent torque rating for this series is 201-300 lb-ft; check application pages for the torque rating specific to this configuration. Internal parts are common to the Chelsea 442 Series.
