489XLAHX-T5XK Chelsea PTO Assembly

The Chelsea 489 Series Power Take-Off Assembly, part number 489XLAHX-T5XK or 489XLAHXT5XK, mounts directly to an 8-bolt transmission opening on compatible Eaton/Fuller, Volvo/Mack, and other manual transmissions. The one-piece cast iron housing eliminates the adapter plate needed on many competing designs, reducing potential leak paths and cutting installation time. This unit uses an air shift and delivers an SAE B 2 or 4-bolt flange output with a 7/8" 13-tooth SAE B shaft. Intermittent torque capacity for the 489 Series runs 201-300 lb-ft (301-400 Nm); shaft power is rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. Internal components are common to the Chelsea 442 Series, supporting parts availability across the line. Call us to confirm proper fit for your transmission application.
