The Chelsea 489 Series Power Take-Off, part number 489GHAHX-W3RA or 489GHAHXW3RA, is an 8-bolt mechanical shift PTO designed to mount directly to manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates the adapter plate that is a common leak path on other designs, while sharing internal parts with the proven 442 Series for the same 250 lb-ft torque capacity. Output is through a 1-1/4" round keyed shaft, and the series offers 27 output configurations including a 360-degree rotatable flange with a greaseable shaft to reduce spline fretting and corrosion. Intermittent torque rating for the 489 Series ranges from 201 to 300 lb-ft. Call us to confirm proper fit for your transmission and application.
