TROUBLESHOOTING GUIDE Power Steering System 305 Dee Cee Court • White House, TN 37188 • Ph: 615-672-5117 • Web: POWER STEERING SYSTEM OVERVIEW KSE’s Power Steering Pumps and Tandem Pumps (PS+Fuel) have been proven to give excellent power steering performance under racing conditions for various applications including sprint cars, modifieds, and late models. KSE’s power steering pumps work well with stock power steering gears (i.e. Saginaw), power rack pinions, and various aftermarket units. All of KSE’s power steering pumps are specially designed positive displacement gerotor-style pumps which can be characterized by their high mechanical and volumetric efficiencies with smooth flow and low pulse ripple. It is important to note that a positive displacement pump (vane, gerotor, gear, etc.) creates flow, not pressure – pressure is only a signal of the resistance to flow! When troubleshooting any power steering system, it is always important to remember that there are many components and/or factors which can affect the performance of the system, including: • Power Steering Gear / Rack Pinion • Power Steering Pump • Power Steering Fluid Reservoir • Plumbing – Hoses Fittings • Steering Geometry Tire Scrub • Steering Ratio - Linkage Steering Quickener Notably, the two most commonly overlooked items in this list (which account for a large majority of all power steering issues) are the power steering fluid reservoir and the power steering plumbing – namely the pump suction line. A well designed power steering fluid reservoir should have these features: • The tank must be vented (i.e. vented cap). A non-vented tank will cause pump seal failure. • Should be tall in shape and hold a minimum of 16 oz. of fluid.
