The Chelsea 489XRAHX-A5AZ or 489XRAHXA5AZ is a 489 Series Power Take-Off assembly built around a one-piece cast iron housing that bolts directly to an 8-bolt transmission opening on compatible Eaton/Fuller, Volvo/Mack, and other manual transmissions. The integral housing eliminates the need for an adapter plate, reducing potential leak paths compared to multi-piece designs. Shift is wire/cable mechanical. The 1-1/4" round output shaft (with key) is driven by tapered bearings rather than needle bearings for improved load capacity. Intermittent torque for the 489 Series is rated at 201-300 lb-ft (301-400 Nm), with shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are common to the Chelsea 442 Series, simplifying parts sourcing and service. Call us to confirm proper fit for your transmission and application.
