Description
The Chelsea 489 Series Power Take-Off Assembly, part number 489XAITX-A3RA or 489XAITXA3RA, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, Tremec, and Eaton Endurant, no adapter plate needed. The one-piece cast iron housing gives torque capacity comparable to the 442 Series, rated at 250 lb-ft intermittent. Shift is accomplished via wire/cable mechanical actuation with an electric-over-air option available. Output is a 1-1/4″ round shaft with key, delivering 24 HP at 500 RPM and 48 HP at 1,000 RPM. Tapered bearings replace the needle bearings found on some competitive designs for improved load-bearing capability. Available in a kit-style configuration for straightforward field service.
