Altec DM series Hydraulic temperatures

Is anyone else having issues with Altec Digger Derricks creating a lot of heat in the hydraulic system causing the pulsars to fail and create eractic operating issues? It appears that this is happening on units built on or around 2012-2013 before everything was transitioned over to the "B" series design. If you are experiencing this what solutions have you come up with? We have thousands of dollars invested in trucks changing out almost everything and the problem still exists.
