     Warning!!! - The following post will have best impact on those who know what  a Sauer Danfoss series 90 is and have an idea on what's inside these pumps.

     I never counted, but now that I thought of it I am pretty sure that I've assembled and disassembled Sauer Danfoss series 90 pumps AT LEAST 500 times - which for most people would be more than enough to memorize what goes where, and be able to perform the assembly under any imaginable and unimaginable conditions, blindfolded, and with the hands tied behind the back... (this is a joke, see, it is impossible to assemble a pump with the hands tied behind the back...)

     Apparently, the 500 odd times were not enough for yours truly (at least not THAT day), who, AFTER tightening with the correct scientific torque ALL of the screws, was about to mount the displacement control (while whistling a merry tune, must I confess), when he discovered that the feedback lever is pointing in the wrong direction! (correct position is like this). It doesn't get any greenhorn-er that that!!!

     Seriously now, no matter how much experience a technician/mechanic/engineer has, he WILL MAKE A STUPID MISTAKE at some point. It's inevitable. What can and should be avoided, however, is the following inadequate reactions and hysterical self-beatings.

   My advice for such situations - use Homer's approach, by saying something like this (or this), correcting your mistake, and leaving it behind....
