Examples of Low Quality Aftermarket Spare Parts for Komatsu Pumps

     Apparently, copying industry can't keep up with the constant progress of Komatsu pumps. Here's a couple examples - picture 1 shows the aftermarket barrel for Komatsu HPV 112 - the manufacturer limited himself to copying the external dimensions, and left out the "patented stuff", like the uneven port pitch of the original Komatsu barrel, or the optimized and widened oil channels. One could argue at this point if the uneven pitch makes that much of a difference, but it does help you tell the barrel is not genuine just by looking at it.

    Picture 2 shows the swashplates for the same pump model, the casting quality of the aftermarket swashplate is notoriously low, as well as the finish.

   Will such parts work? Yes they will, but... they will last less, and that's why they should also cost less, like a lot less...
