The Chelsea 645XDBX-3XX or 645XDBX3XX is a power takeoff assembly that mounts to a 6-bolt transmission opening using a 6-bolt PTO interface. A key design feature is the 45-degree downward angular offset, which repositions the PTO output away from common underchassis interference points, useful on vehicles where a straight-mount unit would conflict with frame rails, drivelines, or other underbody components. The 645XDBX-3XX uses the same input gear set as the Chelsea 442 Series, making it a practical fit where that gear geometry is already specified. Call us to confirm proper fit for your application.
