The Chelsea 489 Series Power Take-Off, part number 489GHAHX-A3GA or 489GHAHXA3GA, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Volvo/Mack, and Tremec without an adapter plate. The one-piece cast iron housing eliminates the adapter plate leak path common to earlier designs. This unit delivers up to 250 lb-ft intermittent torque, matching 442 Series capacity, with shaft power rated at 24 HP at 500 RPM and 48 HP at 1,000 RPM. The 1-1/4" round output shaft ships in a standard or keyed configuration. Tapered bearings replace needle bearings for improved load capacity. Call us to confirm proper fit for your transmission and application.
