The Chelsea 645ZFNX-4XX or 645ZFNX4XX is a 6-bolt power takeoff assembly designed to mount on a 6-bolt transmission opening. Its defining feature is a 45-degree downward angular offset that repositions the PTO body to clear common interference points found in tighter cab and chassis configurations. The unit shares its input gear set with the Chelsea 442 Series, which simplifies parts sourcing for shops already familiar with that platform. Pro Gear and Transmission sells this as a genuine Chelsea assembly. Call us to confirm proper fit for your specific transmission and chassis setup before ordering.
