The Chelsea 489 Series Power Take-Off Assembly, part number 489GHAHX-V5GB or 489GHAHXV5GB, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton Fuller, Mack, and Tremec, with no adapter plate required. The one-piece cast iron housing delivers up to 250 lb-ft intermittent torque, matching the capacity of the Chelsea 442 Series. Shift actuation is wire/cable mechanical. The 1-1/4" round output shaft with key supports shaft power of 24 HP at 500 RPM and 48 HP at 1,000 RPM. Strong tapered bearings replace needle bearings for greater load capacity. Internal parts share commonality with the 442 Series, simplifying service. Call us to confirm proper fit for your specific transmission and application.
