Continuing the "perfect pump test bench saga" with Part Two.
28 March, 2021
Today I am taking another stroll down memory lane to the early days of my industrial hydraulics venture, when I would do nothing but overhaul hydraulic pumps and motors and dream about the perfect test bench.
Can you imagine a hydrostatic transmission malfunction that would cause the wheels of the same axis to turn in opposite directions (burning rubber and all)? It's a lot simpler than it sounds. A story from the "pre-COVID era" - Hydrostatic Drive, Sudden Stops, and Wheels Turning The Other Way Around.

I was not sure where to put this article, and in the end, decided to place it in the section containing tips. It's an experiment I did, but it seems like a workshop tip as well. Lots and lots of pictures in Electrolytic rust removal - I am sold!
I love tools. The best present I could ever get is a tool. New or used, it doesn't matter, as long as it serves a purpose and makes my life easier I am happy. And so, in today's post I talk about a handy tool that I have been using for a long time - a (relatively) low-cost oval gear flow meter, which I believe to be The Perfect Instrument for Measurement of Low and Extremely Low Flow Rates.
You wouldn't believe if I told you how many times I am asked to repair perfectly functional components, which is why I believe it is necessary to (once again!) address the very important matter of Broken Hydraulic Pumps That Don't Need to Be Fixed.

I continue with the topic of clean oil and show you one of the ways to tackle a "proper oil change", using one of my recent service calls as an example. I strongly believe that sharing experiences is important, especially in this field - we all want to get better at what we do, right? So - kicking the 2021 off with Ten Steps to Changing Hydraulic Oil.

The next two weeks will be all about keeping hydraulic systems clean during service and re-commissioning (very important)! I am finishing the old year with an old post about A Way You Can Flush a Closed-Loop Circuit and will start a new year with a new article, in which I will showcase an oil change I did a couple of weeks ago (yes, you heard me right, even a simple oil change can deserve a blog post if done right).

Today's article turned out to be quite long. And full of technical details, as I go along disassembling a White Hydraulics orbital motor. The main point of this article, however, is not the technical features of this model, but a bigger picture that stands behind the way a technician can approach a service task. I warn you - the article has a sad ending... I also just discovered that Google started to place ads in places that ruin the design of the site, so if you see no text - scroll the page down - it was "pushed" down. I'll fix this ASAP. So, a lot of pictures and words in - Back-Engineering for the Sake of Learning Industrial Hydraulics.

I have been working on a post dedicated to reverse-engineering and how practicing it makes you a better hydraulic tech. A walk-through example of how I like to work on hydraulic components that are new to me, presented with the help of a White Drive orbital motor. I won't be able to upload it today - it's "not ripe yet", but I can give an example of how the ability to back-engineer unknown hydraulic components saved my day a couple of years ago. Consider this article a prequel to the one that will come out next week - The Furukawa Battle.
