Hydraulic steering can make or break a trail machine. An inadequate system can over-exercise arm muscles while making tight maneuvers very frustrating. Or, if well designed, a hydraulic steering system can actually contribute to the overall enjoyment of a day in the dirt.
That's because the amount of physical effort it takes the driver to turn the steering wheel relates directly to how well the hydraulic system functions. A poorly designed system or even a simple misuse of parts for a particular application can result in sluggish, and hard-to-use steering wheel - not to mention the ill effect on reliability.
That's why we decided to delve into the subject of hydraulics and address a few common issues, while at the same time contrasting the two popular types of setups we see on the trail. We're going to break this somewhat complex topic into two categories.
Full Hydro Traditionally, this has always been the point where most 'wheelers cross the line between a trail-only rig and a daily driver. This is because most people feel hydraulic systems are unreliable and therefore not suitable for the street. However, this is not necessarily true.
Take a look at the heavy equipment industry: Caterpillar tractors, for example, rely on a variety of hydraulic systems to function, many of which control directional movement. Hydraulic steering systems have their place in several street-driving scenarios, too, though most are found on industrial or agricultural equipment operated at low speeds. These systems are engineered to perform a specific task within a specific range of parameters i.
The problem here - and probably part of the reason why fully hydraulic steering gets a bad rap on the street - is due to system design, or lack thereof.Honda accord catalytic converter scrap value
It all boils down to economics. No common man is willing to invest the millions it took Caterpillar to develop a fully hydraulic steering system reliable enough to pilot its dump trucks down the road safely.
And because there are several sources for hydraulic steering components, all with very little "specific information" about each particular application, it's hard for Joe Consumer to know which widget to install on his own rig.
Full hydraulic steering requires eight major components: Each is equally important to the overall performance of the system. That's why it's most important to build a balanced or matched system.Surgical instruments whatsapp group
Ram Assist For most 'wheelers, the somewhat less expensive, less complex hydraulic assist may be the best option. In most cases, companies offer complete kits for specific vehicle applications like the PSC kit shown above for the '05 Jeep TJ. With an assist setup, your rig's mechanical steering remains intact, enabling the option of manual steering if the hydraulics should fail.
We like this setup for trail rigs that are driven on pavement from time to time. Aside from helping your steering system push around larger meats, a ram assist can function as the ultimate steering dampener, too. At the same time, a ram assist also helps relieve stress on other steering components such as the steering box.
The major difference between hydro-assist and fully hydraulic steering is that hydro-assist is basically a piggyback setup you add on to your existing steering system, while a fully hydraulic system is a stand-alone system relying completely on fluid power.
Reservoir This is the hydraulic fluid or power-steering fluid reservoir that stores the fluid necessary for the system. Think of it as an oil pan. Most power-steering pumps have a reservoir attached right to the pump body. The one shown here is a PSC part.Steering systems.

Steering Valves Satisfy the most demanding requirements for steering applications with steering valves from Eaton.
See Product Information for specific details on each type. Check Valves Designed specifically to withstand the rugged duty cycles of a steering system and perform their functions reliably to prevent kickback in the steering wheel.
Brake Valves Enable the integration of power brakes economically and efficiently in lift trucks where it was traditionally too expensive. Flow Divider Valves Available with bypass type or without restrictor type integral relief valves. Adjustable flow control valves are ideal for applications requiring flow regulation without pressure compensation. Antijerk Valves Provide smoother steering on articulated vehicles, dramatically reducing jerk when steering is stopped quickly or during aggressive direction changes.
GPS Steer Valves Eaton GPS Steer Valves combine all of our advanced proportional valve technologies, resulting in versatile autoguidance steering products for tractors, sprayers, combines, motor graders, scrapers and other off-road equipment. Four Wheel Steer Switching Valves Provide three different types of steering by energizing and de-energizing two high performance, solenoid-operated directional control valves DG4V-3 valves.

Load Reaction A load reaction steering unit couples the cylinder ports internally in the neutral position with the meter gear set. Axle forces are then allowed to return the steering wheel to its approximate original position.
Comparable to automobile steering, gradually releasing the wheel mid turn will allow the steering wheel to spin back as the vehicle straightens.
The cylinder system used with load reaction units must have equal oil volume displaced in both directions. The cylinders should be a parallel pair as shown or one double rod end unit. Do not use with a single unequal area cylinder system. These are the four hydraulic fluid connection ports that make the unit operate. They are as follows:.
The closed center design is not suitable for our use, cannot be used with automotive power steering pumps, and is used on large construction equipment. In this system, a pump can rest when the oil is not required to operate a function. This means that the steering unit valve is closed in the center, stopping the flow of the oil from the pump.
Let me get this out of the way right now. Load sensing has nothing to do with the wheels returning to center, or road feel through the steered wheels back to the operator.
Many many people think that it does, but I'm afraid they are all wrong. The following description of load sensing circuits is taken from Eaton.
More information for those interested is available in the various pdf catalogues and manuals available at the end of this part of the articlein the "resources" section. The use of a load sensing steering unit and a priority valve in a normal power steering circuit offers the following advantages:.

Char-Lynn load sensing steering control units and priority valves can be used with open center, closed center or load sensing systems. Use in an open center system with a fixed displacement pump or a closed center system with a pressure compensated pump, offers many of the features of a load sensing system. Excess flow is available for auxiliary circuits. Listed below are the components of a typical load sensing control circuit and a brief application description.
THIS is the hydraulic circuit feature that is of interest to us. Load Reaction is the infamous "return to center" feature. Note however, that this feature only allows external forces on the wheels to cause a reaction in the steering wheel. That is, it is only permitting the transfer of force, not actually creating it. Without sufficient castor or proper geometry, even with a Load Reaction steering unit, "return to center" and road feel can still be very poor.
On the other hand, with good geometry and alignment, and a Load Reaction steering unit, road feel and return to center can be excellent. If you recall how the steering unit is in fact a combination of valve s and metering unit, it will not be a surprise that there are often depending on manufacturer a number of "optional" valving functions available on steering units.
Most, if not every steering unit I have ever read about that we might possibly use includes one of these. It is a small valve built in to the steering unit that allows the steering unit to act as a small hand operated pump by turning the steering wheelproviding limited manual steering, should the engine, pump or a belt quit. In my experience, the result is that the steering operates almost identically to normal automotive Saginaw power steering with no power.
It is extremely difficult, if not impossible, to manually turn 38" tires at low pressure in a spooled and slugged front axle while sitting still with the engine off.
