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.

On some steering gears, it may be possible to see the gear series or even the identification number while the steering gear is still installed on the vehicle. While it may be difficult to see the identification number until the gear is removed from the vehicle, identifying the series of the gear is a good place to start. A.

Our Technical Service Advisors will be able to assist you in identifying the gear you need. Technical Services hotline (1-800-822-2042) Many steering gear part numbers are a combination of the gear series and the identification number stamped somewhere on the gear. We have followed the same part number scheme for ease of identifying these gears. Dayton Parts will have the top 50 part numbers in inventory in all of their U.S. warehouses (See Section 6 for a list of part numbers in inventory) Orders can be placed online or by calling customer service with the part number you have identified as the necessary replacement gear. Most steering gears that are not in inventory can typically be shipped from our Lewisville, TX warehouse within 48 hours of placing an order. Any steering gear that is not currently being stocked at one of our warehouses can be added to our inventory to be ordered with future stock orders if desired.
