Tech 101
The Cause Behind Rack Leakage
Recently we have seen an increase in our customers sending in their power steering rack and pinions to be rebuilt due to seal leakage. The most common cause of rack and pinion seal leakage is a result of the power steering pump over-heating. When the pump over-heats, it causes the fluid temperatures to rise to a point where it damages the seals not only in the pump, but in the rack and pinions as well. Turn One recommends the power steering fluid temperatures not exceed 275° F. This will insure a long rack and pinion seal life.
Why the Flow Control Spring Shouldn't be Cut
As we covered last month in "Debunking the Shim Kit Theory", the fix to light or twitchy steering is not adjusting the pressure of the power steering pump, rather the flow. Another myth surrounding the power steering pump pressure is cutting the flow control spring. Just like the shim kit theory, this is also false.
Debunking the Shim Kit Theory
Ever have light steering effort or twitchy steering? At some point or another, you probably have. It seems that somewhere along the line, a rumor started that the fix to this dilemma is to use a shim kit on the pressure relief valve to lower pressure in the power steering pump. Unfortunately, this is a myth.
Pressure vs. Flow
Fact or fiction? There are a lot of myths surrounding power steering and its functions. Most of these myths revolve around the power steering pressure and flow rate settings.In this article, we discuss power steering pressure and flow rate and their respective functions in the power steering system.
