The Chelsea 489 Series Power Take-Off Assembly, part number 489GHAHX-P5RB or 489GHAHXP5RB, mounts directly to the 8-bolt transmission opening on most manual transmissions including Eaton/Fuller, Volvo/Mack, and others, eliminating the need for an adapter plate and reducing potential leak paths. The one-piece cast iron housing delivers the same intermittent torque capacity as the 442 Series. Shift is wire/cable mechanical, and the output shaft is a 1-1/4" round with key. This unit uses pressure lubrication (P designation) and shares internal parts with the 442 Series, simplifying service. Call Pro Gear and Transmission to confirm proper fit for your application.
