I did an interesting assistance call in November which, as usual, involved a piece of mining equipment. I want to go through the troubleshooting process and show you how, despite my "expertise", equipment knowledge and state of the art diagnostic tools, I still found the malfunction only by sheer dumb luck.

Returning form the usual end of the year maintenance week, which I spent cleaning oil tanks and swapping filters in our beloved mine, I only have the strength to ask you one question: What is the first thing that comes to your mind when you hear the word "flathead"?
Know Your Code Names! - a post which, among other things, contains a short trip down the memory lane. Also - I finally updated the contact page. It has my linkedIn now, so if you're into this kind of thing - feel free to connect.
Been doing some work on closed-loop transmissions this week, which made me go back to an old series of posts devoted to closed-loop null adjustment, and, as usual - I am re-writing everything. So, here's the first part - Finding Zero.
I had this little project on hold since last year, and finally managed to scrape together some time to finish it - and was very surprised to run into an unexpected problem with the installation of a Danfoss JS1-H joystick. At this point I am not sure if I was unlucky and got a "lemon" from the Danfoss, or if it's just the way these joysticks are supposed to be, but I will definitely investigate, and (with your help) will get to the bottom of this. For now - I'll keep the "suspense" by introducing you to the Unexpected Problem With Danfoss JS1-H Joystick Installation.

Last week I installed a custom built Danfoss JS1-H heavy duty joystick control system on a Terex tele-handler. The build went fine but I ran into a very peculiar joystick malfunction that I wasn't expecting... I did fix it, and I did reach our for Danfoss to see if they can tell me anything about it. So far they've been silent... So I will wait for another week before posting about this build... Anyhow - do you know The Importance of Relief Valve Settings Verification?

This is one of my first https:// pages, so, please, do let me know if there're issues with the way the page is shown. Apparently this is another thing that I will have to re-factor "all over the blog". For "security" reasons... So, you can now (very securely) find out what is the Best Tool to Learn Hydraulic Pump Troubleshooting

Three hydraulic myths are added to the Tip Jar. Also - a small update on the Wireless page - as I am refactoring the App for multi-point profiles, I decided it would be nice to update the chart and log a progress point.

I've been slowly but steadily re-factoring old pages to the newer template, and often I find that my old posts are incomplete or even incorrect, so, instead of re-writing the HTML I end up re-writing the complete post. Only God knows why I keep doing that... Anyways, here's another one, remastered, on Three Simple Checks you should consider doing before bench testing a pump or a motor with unknown history.
If you don't know it yet - simple stuff that is so obvious for us, people who deal with hydraulics on a daily basis, can be the complete opposite for "normal folks". Here's an example: Not So Obvious Obvious. (Older article, re-done with mistakes corrected).
