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.
One method for reducing the fluid temperatures is to use a Turn One high performance power steering pump. All of our power steering pumps are designed to reduce horsepower consumption at high RPM’s, which in turn, reduces the fluid temperatures. The horsepower that the pump consumes is converted to heat, therefore a reduction in horsepower consumption will result in a reduction in fluid temperature. In most cases, Turn One can also rebuild your existing power steering pump to gain reduced horsepower consumption and reduced fluid temperatures. In extreme conditions, a power steering cooler may be needed if adding a Turn One power steering pump does not reduce your fluid temperatures below 275° F.
