Description
The Chelsea 489 Series Power Take-Off, part number 489GQAHX-V3XK or 489GQAHXV3XK, is an 8-bolt 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 adapter plate and reducing potential leak paths. Intermittent torque rating for this series is 250 lb-ft (339 Nm); check application pages for ratings specific to your installation. The wire/cable mechanical shift operates a 1-1/4″ round output shaft. Shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal parts are common with the Chelsea 442 Series, making service and parts sourcing straightforward. Call us to confirm proper fit for your transmission.
