Negative Flow Control vs Load Sensing - Which One is Better?
The pre-loading of a cylinder block is actually not a mandatory condition for the high volumetric efficiency of an axial piston hydraulic unit. This troubleshooting case demonstrates this pretty well (along with some "creative" testing) - Cylinder Block Lift in a Fixed Displacement Hydraulic Motor
Knowing a thing or two about what is at "the other end of the pump shaft" can't hurt a hydraulic tech. A real life example of this in - "You forgot about the Power factor!"
After talking so much about post-compensation and whatnot, it's only logical that in today's post I am addressing the flow sharing in its "pre-compensated flavor" - Pre-Compensated Flow Control With Flow Sharing?!!

Just a few thoughts about how can one develop an Excessive Case Pressure in Pumps With Internal Drain-to-Suction Line Connection.
Never, but Never Trust a New Hydraulic Pump or Motor.
Continuing the "perfect pump test bench saga" with Part Two.
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.
To Dither or Not to Dither - That is the Question!
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!
