The Chelsea 645GFEX-3HQ or 645GFEX3HQ is a power take-off assembly from the Chelsea 645 Series, designed to mount to a 6-bolt transmission opening using a 6-bolt PTO flange. Its defining characteristic is a 45-degree downward angular offset that repositions the PTO body away from chassis components, reducing interference with nearby driveline or frame obstructions that a straight-mount PTO would contact. The 645 Series shares its input gear set with the Chelsea 442 Series, meaning shops already familiar with 442 Series service procedures will find many of the same internal components. A full parts breakdown, exploded views, and item numbers are available in the Chelsea 645 Series Parts Manual linked below.
