In chapter 13 of The Hydraulic Maintenance Handbook, I discuss the principle of engineering out issues that have the potential to cause recurring maintenance problems. Since maintenance occurs after the event, that is, after the machine is designed and built, this strategy is very much a retrospective one. Which means it’s desirable and preferable not to engineer in such … Read more

How Much Hydraulic Oil Consumption is Acceptable?
What is an acceptable level of oil loss for a hydraulic machine:
a). Zero
b). 2%
c). 5% or more?
In a perfect world, the right answer would of course be zero. But in reality, the true answer is 5% or more–of tank oil volume per year. And the reason I can say this with confidence is because total hydraulic … Read more
What You Must Understand BEFORE Carrying Out Repairs on a Hydraulic Machine
In chapter 13 of The Hydraulic Maintenance Handbook I discuss in detail the elimination of problems by engineering them out. An obvious example of this strategy is, if a hydraulic system has tapered thread adapters, their replacement with a more reliable type of connector eliminates the possibility of recurring leaks. Job done. And if an oil to water heat exchanger … Read more
