Power Steering Racks

The power steering is essentially the same as the hydraulic power steering, but without the rack. The power steering is mounted only on certain types of vehicles, such as tractors, since, having a certain delay in response and being not very fast in steering, it is more suitable for slow vehicles. As a mechanical organ that controls the steering and consequently the entire car, it requires care and competence. Its revision is carried out with the utmost care, always replacing the terminals and bellows, grinding the stator and gaskets; it is then subjected to a strict and scrupulous testing, with bench test with hot and cold pressure cycles, using a high pressure pump that far exceeds the normal requirements of the vehicle. Everything that does not pass this procedure with full marks is discarded or demolished.

The hydraulic rack-and-pinion mechanical steering was followed by a new system called EPHS, or the mechanical hydraulic pump was replaced by an electronic power steering pump.
