The Chelsea 489 Series Power Take-Off, part number 489XLAHX-M5RA or 489XLAHXM5RA, is an 8-bolt PTO assembly designed for 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. Output is through a 1-1/4" round shaft with key. Intermittent torque capacity for the 489 Series is 250 lb-ft (339 Nm); shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common to the Chelsea 442 Series, and the unit features tapered bearings rather than needle bearings for increased load capacity.
