The Chelsea 489 Series Power Take-Off, part number 489XRAHX-W3XK or 489XRAHXW3XK, is an 8-bolt PTO assembly built for manual transmissions including Eaton Fuller, Volvo, Mack, and Tremec applications. The integral one-piece cast iron housing mounts directly to the 8-bolt transmission opening, eliminating the need for a separate adapter plate and reducing potential leak paths. Shift is accomplished via wire/cable mechanical actuation. The output is an SAE B 2 or 4-bolt flange with a 7/8" 13-tooth SAE B shaft. Intermittent torque rating for the 489 Series is 250 lb-ft (339 Nm); shaft power is 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are shared with the 442 Series, which simplifies parts stocking. Call us to confirm proper fit for your transmission.
