The Chelsea 489 Series Power Take-Off Assembly, part number 489XFAHX-W5GK or 489XFAHXW5GK, is an 8-bolt PTO built for manual transmissions including Eaton Fuller, 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. This unit delivers the same intermittent torque capacity as the 442 Series - up to 250 lb-ft (339 Nm) - with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Output is via a 1-1/4" round shaft with key. The wire/cable mechanical shift mechanism and kit-style construction simplify service. Internal components are common to the Chelsea 442 Series. Call us to confirm proper fit for your specific transmission.
