Identifying the Gear Components

Pressure and Return Ports: The connection points for the hydraulic lines to and from the power steering pump. Typically one of the ports will have an embossed letter in the casting. “P” for the pressure ports or “R” for the return port. Valve Housing: This casting is bolted on to the cylinder bore of the gear housing and contains the mechanical valve of the steering gear. Gear Housing: This is the main casting of the steering gear and contains the rack piston and output shaft. ID Pad: On late model TRW gears, the gear part number is stamped on this machined surface. Auxiliary Port: Some gears are equipped with 4 lines to provide hydraulic assist from the master gear to an auxiliary gear mounted on the opposite frame rail. If you have a 4 line gear, one of the auxiliary ports is on this end of the gear housing or in the “bowl” of the gear housing around the output shaft.
