How do I bleed my power steering system? 
Review our bleeding instructions here.

What is the fill level on a PSC Remote Fluid Reservoir?
Halfway between the upper solid black line of the PSC logo and the weld bead at the top of the reservoir (https://www.flipsnack.com/runpsc/psc-power-steering-bleeding-procedures.html).

Where does this rubber hose on the top of my Remote Fluid Reservoir connect?
On offroad applications, the rubber hose inserted into the 90° elbow is the vent line. This should be connected to a PSC Fluid Anti-Splash Valve.

What does JIC mean? What is the difference between JIC and AN?
JIC is an abbreviation for Joint Industries Council, the first entity to standardize industrial use fittings. JIC fittings feature a 37° flared seat on both male and female threaded connections.
AN stands for Air Force-Navy Aeronautical Design Standards. Fittings manufactured to this designation are MIL-SPEC (US Military) standard.

What is “death wobble”? How can I fix it?
Death wobble is caused by loose or damaged mechanical steering components, not the hydraulic components, e.g. pump or steering gear. It can be a result of incorrectly installed mechanical steering or suspension parts.
The first thing that should be verified is if anything is bent or broken. Look at all of the front suspension components, and if anything's damaged, the first priority is to replace it.
Below is a checklist of possible causes from MOST PROBABLE to LEAST PROBABLE.
• Front Track Bar
• Ball Joints
• Drag Link/Tie Rod Ends
• Upper Control Arms
• Lower Control Arms
• Suspension Bushings
• Steering Stabilizer
• Steering Knuckles
The front track bar, drag link, steering knuckles, ball joints, steering stabilizer, upper and lower control arms should be checked for damage or excessive wear.
Verify that all hardware is properly tightened to the correct torque specifications.

 


What type/brand of power steering fluid does PSC recommend?

SWEPCO 715 manufactured by SWEPCO

Why?
The #1 reason power steering pumps fail is due to cavitaition aka fluid aeration. The #1 cause of fluid aeration is fluid temperatures in excess of 180°F.
SWEPCO 715 has a very aggressive anti-foaming formula and in testing with 15 other leading fluids used for power steering systems, it provides three (3) critical benefits:
1) Aggressive suppression of fluid aeration, especially as the fluid temperature increases
2) Quiet pump operation
3) Broad temperature range for a variety of climates

SWEPCO 715 is not readily available to me, are there any alternatives?
As an alternative to SWEPCO 715, PSC recommends using AC Delco Power Steering Fluid.
For vehicles being used in regions with extended periods of sub-freezing seasonal temperatures, PSC recommends using AC Delco Cold Climate Power Steering Fluid.

Is a fluid cooler recommended?
Yes! PSC recommends using a fluid cooler to protect your investment and to ensure efficient performance in all driving environments. The most detrimental effect of excessive heat in the power steering system is the breakdown of the power steering fluid which affects its ability to lubricate the vital components of the steering system, namely the pump.
Fluid temperatures should be maintained at approximately 120°F - 160°F for optimum performance, and should never be allowed to exceed 180°F.
It is strongly recommended to install fluid coolers outside the engine bay and slightly below the level of the power steering pump.

What happens if I mix fluids?
With the exception of AC Delco Power Steering Fluid, we do not recommend mixing fluids as it will dilute the anti-foaming strength of the SWEPCO 715.
However, in the event of an emergency, use whatever products are immediately available to enable the vehicle to safely exit the trail. Once the vehicle is at home base, drain and flush the system, replace the filter, and refill with SWEPCO 715.

A Fluid Change Kit can be purchased here, www.pscmotorsports.com/power-steering-fluid/psc-flk729.html

When installing new PSC components, do I need to flush the power steering fluid system first?
Generally, flushing the system is advised when replacing a component, e.g. catastrophic failure of a pump. Metallic debris from a catastrophic component failure can potenially damage another component in the system, e.g. steering gear or hydroboost brake unit.

Additionally, flushing the power steering system is advised as part of regular system maintenance to maintain optimal performance in the field. For example, on vehicles regularly deployed in intermediate to advanced off-road environments, it would be recommended to flush, fill, and change the filter at least once a season.

Why is fluid spilling out of the top of the reservoir and/or SR-VT Fluid Anti-Splash Valve?
The main cause of fluid loss from the reservoir is overfilling. Verify that the fluid level is halfway between the upper solid black line of the PSC logo and the weld bead at the top of the reservoir (www.flipsnack.com/runpsc/psc-power-steering-bleeding-procedures.html).

At higher pump RPMs, excessive fluid aeration becomes the secondary reason for fluid loss. Excessive air and pressure in the system will want to push up and out thru the reservoir vent.

The number on the white PSC sticker (see example below) is an internal Manufacturing Tracking Serial Number, it is NOT a part number.

Where can I find the part number of my PSC steering gear?
PSC Steering Gear part numbers are typically stamped into the case or input shaft gland nut:

Contact Us if you need assistance.

Which port on the steering gear is the high-pressure port?
The LARGER of the two (2) female ports is ALWAYS the high-pressure "IN" port, or the connection directly to the high-pressure output of the pump. 
On vehicles produced before 1979 and earlier, the ports have inverted flare seats and measure SAE 11/16. 
On vehicles produced 1980 and later, the ports have metric o-ring seats and measure 18MM-1.50. 
Most PSC steering gears have indicators for the high and low-pressure ports. Before installing the component, inspect case for marks that indicate the proper line connections as seen here:


When using JIC adapter fittings, verify the line connections are correct before starting the engine. Improperly installed lines can cause damage to the steering gear.
Some specialty steering gears, especially for race applications, the ports can be the same size. Contact Us for more information.

I’m installing a cylinder assist system on my vehicle; which line goes where when connecting the steering gearbox to the steering assist cylinder?
For most applications, please follow this diagram.
Most JK, JL, and JT PSC steering gears have indicators for the Driver and Passenger ports. Before installing the component, inspect case for marks that indicate the proper line connections as seen here:

What are these o-rings zip-tied to my PSC Steering Gear?
These are replacement o-rings for the factory high-pressure hose assembly if it is being reinstalled. If the factory hose assembly is not being installed, these o-rings can be discarded. 

I am not going to install the Assist Cylinder until later, do I leave these steel JIC cap nuts on the ports?
Yes. Snug them down and the vehicle can be operated as normal.

What size are the Cylinder Assist™ ports on my PSC Steering Gear?
The Cylinder Assist™ ports are -6 JIC for #6 (3/8") ID high-pressure hose.

My steering wheel will not return to center, how can I fix it?
The return-to-center issue can typically be resolved by adjusting the positive caster alignment setting after the installation of a new steering gear and/or other suspension modifications.

If the steering gear is suspected to be the cause, remove the steering gear from the vehicle and test it on the bench. Lightly attach a pair of vice grips to the input shaft (be careful not to damage the splines or mar a smooth input shaft) and rotate by hand. If binding or any other anomaly presents, then the steering gear most likely needs to be adjusted or repaired.
Contact Us for further information.

Why is my steering touchy/sketchy (hyper-sensitive) at highway speeds?
It is important to have the vehicle aligned by a qualified Off-Road Specialist after the installation of a PSC Cylinder Assist™ Steering Kit, any suspension modifications including lift kits and adjustable A-arms, and/or adjusting the axle pinion angle. An incorrect positive caster alignment setting is the leading cause of steering hyper-sensitivity.

I am experiencing bump steer, how do I fix it?
Bump steer is typically caused by one of two things: A) lifting a vehicle incorrectly or B) loose, broken, or bent suspension components.

Improperly lifting a vehicle doesn’t just mean installing something incorrectly, it mainly refers to the angles of the steering and suspension components. When a lift kit is added to a vehicle, the geometry of the mechanical aspect of the steering and suspension is changed and this requires an adjustment to keep the angles correct. Verify that the angles of the track bar and drag link are parallel to each other.

Sometimes, adjustments will require additional third-party parts, like a new bracket assembly or an adjustable version of a component.

What is the torque specification for the Pitman arm?
For most steering gears with a 1-1/8" diameter sector shaft, the torque value is 180 ft lbs. The nut size is 7/8 and requires 1-5/16 socket.
The torque value for PSC Big Bore steering gears installed on JK, JL, and JT is 220-225 ft lbs. The nut size is 30MM and requires a 46MM socket.





Where can I find the part number of my PSC pump component?
PSC pumps do not have a part number stamp. As a reference, the three different types of pumps we offer can be found here.
The number on the white PSC sticker (see examples on General Information tab) is an internal Manufacturing Tracking Serial Number, it is NOT a part number.

How do I bleed my power steering system? 
Review our bleeding instructions here.

What is the fill level on a PSC Remote Fluid Reservoir?
Halfway between the upper solid black line of the PSC logo and the weld bead at the top of the reservoir (https://www.flipsnack.com/runpsc/psc-power-steering-bleeding-procedures.html).

Is there a different bleeding procedure if I have hydroboost braking?
Yes! After completing Steps 1-14 of the bleeding procedure, with the engine off, apply and release the brake pedal 5-10 times to purge the accumulator reserve pressure. With your foot slightly depressing the brake pedal, start the engine. The brake pedal should drop and then push back against your foot. Turn the steering wheel until lightly against the steering stop. After approximately five (5) seconds, return the wheels to the center, straight-ahead position and turn the engine off. Apply and release the brake pedal. There should be at least one (1) power assisted brake application. 

Should I run an overdrive pulley on my pump?
An overdrive pulley can be used to improve steering performance at low engine RPMs, a driving condition typically found in low-speed, advanced offroad terrain environments.
As a general rule, most pumps start to create usable pressure at approximately 1100 pump RPM. Use this online pulley ratio calculator to see the difference an overdrive pulley can make on your application.

I have changed the pulley size on my pump, how do I find out what belt size I need?
Use this Wikihow to determine an overall length and then visit your local auto parts retail store to experiement with a few sizes to find the best fit.
