The Chelsea 489 Series Power Take-Off Assembly, part number 489ZRDAX-V5XK or 489ZRDAXV5XK, mounts directly to an 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec. The one-piece cast iron housing eliminates the adapter plate needed on many competing units, reducing both installation time and potential leak paths. Intermittent torque capacity is 250 lb-ft (339 Nm), matching the Chelsea 442 Series. Output shaft is a 1-1/4" round with key, and shift is wire/cable mechanical. Output power runs 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace the needle bearings found in earlier designs for greater load-bearing capability. Call us to confirm proper fit for your application.
