This single-stage cylinder was 6" bore x 3" rod x 14' stroke. The OEM was in a terrible position because they had 80 machines that could not ship by the end of the month deadline due to the squealing - which could be heard blocks away. The OEM was demanding that the cylinder manufacturer send a crew of men to change out all 80 cylinders! But what could the problem be? Seal stick and slip? Excessive stroke speed? Internal leakage? Load-control valve? What else? How would you approach this situation?</div> <p><a href="http://hydraulicspneumatics.com/blog/troubleshooting-tales-squealing-hydraulic-cylinders" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/troubleshooting-tales-squealing-hydraulic-cylinders#comments Hydraulics At Work Tue, 06 Sep 2016 04:33:00 +0000 39931 at http://hydraulicspneumatics.com The REAL Value Of The Humble Hydraulic Symbol http://hydraulicspneumatics.com/blog/real-value-humble-hydraulic-symbol <div class="node-body blog-body">As most hydraulic technicians know, there's usually a better than even chance that a schematic diagram will not be available for the hydraulic machine they've been called in to troubleshoot.

It was one of many he owned over the years, but this one was different. It was the first I'd seen equipped with a hydrostatic transmission for the ground drive. The infinitely variable and step-less control afforded by a hydrostatic transmission was quite an advance over the mechanical gearbox with a variable speed input used in earlier models... </div> <p><a href="http://hydraulicspneumatics.com/blog/problem-destroying-your-hydrostatic-transmission-video" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/problem-destroying-your-hydrostatic-transmission-video#comments Hydraulics At Work Tue, 09 Aug 2016 04:26:00 +0000 39631 at http://hydraulicspneumatics.com Hydraulic Troubleshooting: Do As I Say; Not As I Do! http://hydraulicspneumatics.com/blog/hydraulic-troubleshooting-do-i-say-not-i-do <div class="node-body blog-body">Hydraulic troubleshooting as a logical process of elimination which begins with checking the easy things first. This emphasis on investigating the easy things first may seem so elementary your inclination may be to disregard this advice. Certainly, if you DO follow a logical process of elimination, you will get a result - regardless of whether you check the easy things first or not. It's just that if you leave anything that's easy to check until last - you'll kick yourself for not giving it your attention in the beginning.</div> <p><a href="http://hydraulicspneumatics.com/blog/hydraulic-troubleshooting-do-i-say-not-i-do" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/hydraulic-troubleshooting-do-i-say-not-i-do#comments Hydraulics At Work Tue, 02 Aug 2016 05:31:00 +0000 39471 at http://hydraulicspneumatics.com How And Why To Monitor Hydraulic Filter Condition http://hydraulicspneumatics.com/blog/how-and-why-monitor-hydraulic-filter-condition <div class="node-body blog-body">Continuous monitoring of the filter elements in a hydraulic system can provide valuable clues to the performance of the filter and the condition of the system.</div> <p><a href="http://hydraulicspneumatics.com/blog/how-and-why-monitor-hydraulic-filter-condition" target="_blank">read more</a></p> http://hydraulicspneumatics.com/blog/how-and-why-monitor-hydraulic-filter-condition#comments Hydraulics At Work Tue, 26 Jul 2016 04:55:00 +0000 39381 at http://hydraulicspneumatics.com How To Store Hydraulic Cylinders - Part 2 http://hydraulicspneumatics.com/blog/how-store-hydraulic-cylinders-part-2 <div class="node-body blog-body">In my previous post, I discussed the procedure I use when preparing hydraulic cylinders for storage.
