Heavy duty vehicles (just like any other type of vehicle) are starting to look a lot different today. Maybe you can't see the differences on the outside, but under the hood, change is happening. Perhaps the biggest change in vehicle technology in the past two decades is the transition from hydraulic to electronic power steering, and those advancements are finally making their way into the heavy duty segment.
The aftermarket is one of the most valuable resources for power steering rebuilders. In order to find the parts you need at the right combination of price and quality, aftermarket manufacturers often provide a plethora of options. However, there's one glaring place where the aftermarket is lacking when it comes to replacement parts: heavy duty power steering hard parts.
Having a base of knowledge in your rebuilding specialty is crucial for any rebuilder worth his or her salt. However, the specifics of particular brands and parts can throw your normal routine for a loop. One such example of a part with unique challenges in the heavy duty steering arena is ZF gears. What you might not know is that there are some specific reasons why disassembling and rebuilding a ZF gear presents so much difficulty. Today, we'll be discussing the common pitfalls in a ZF gear rebuild as well as some tips to help you overcome them.
Heavy duty vehicles, including their power steering systems, rely on components that can stand up to their high pressure operations. From the biggest systems to the smallest parts, you need to be sure everything is able to stand up over time, especially when rebuilding a unit that should have many more miles to go. Today, we're going to discuss one of the smallest parts that has the biggest impact on the success of an HDPS rebuild or remanufacture: the poppet valve.
As most of us in the automotive aftermarket and service industries know, OE manufacturers don't always get things right the first time. But when subsequent attempts to improve a product or part continue to fail, where can you turn for a better solution?
