The Chelsea 489XRAHX-V3AZ or 489XRAHXV3AZ is an 8-bolt power take-off from Chelsea's 489 Series, designed to mount directly to the 8-bolt opening on most manual transmissions including Eaton Fuller, Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates the adapter plate that standard PTOs require, reducing both mounting time and potential leak paths. This unit uses wire/cable mechanical shift and delivers intermittent torque in the 201-300 lb-ft range, with a 1-1/4" round keyed output shaft. Tapered bearings replace needle bearings for greater load-bearing capability. Call us to confirm proper fit for your application.
