The Chelsea 489 Series Power Take-Off, part number 489XSAHX-A4XY or 489XSAHXA4XY, mounts directly to 8-bolt manual transmission openings including Eaton Fuller, Eaton Endurant, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates the adapter plate leak path while delivering intermittent torque in the 201-300 lb-ft range. Output is delivered through a DIN 5462 pump mount with a DIN 5462 shaft (B8x32x36), and shift is accomplished via air shift actuation. The 489 Series shares internal parts with the Chelsea 442 Series, uses tapered bearings instead of needle bearings for greater load capacity, and supports 27 output configurations. Call us to confirm proper fit for your specific transmission and application.
