The Chelsea 489 Series Power Take-Off, part number 489ZRDAX-S5SQ or 489ZRDAXS5SQ, is a mechanical-shift PTO designed for 8-bolt manual transmission openings. The one-piece cast iron housing bolts directly to the transmission without an adapter plate, eliminating a common leak path.

The output shaft is a 1-1/4" round keyed style. Internal parts are common to the Chelsea 442 Series. Call us to confirm proper fit for your application.
