Cylinder internal heat/Hydraulic oil overheating

   It will generate heat and you should be able to feel the difference in temp compared to a good cylinder. Later Bob

   If you're travelling much, bad seals in the swivel joint will also heat the oil.

   As will a worn pump

   So basically anywhere hydraulic oil can leak will cause heat. So the infrared thermometer to pinpoint heat source could lead you to the problem right?

   Exactly.

   One more thing.. when you look at this video https://www.youtube.com/watch?v=KmTlbNAG2f8 Would you say that the problem is cavitation between the thank and the pump? it makes quite a bit of sound and you can see the erratic shaking move cause by the air in the actuator? Make sense or not? thanks

   An hyd oil leak, roughly translated means, works good until it gets warmed up. If you have an infared thermometer you can work the machine and pin point the problem with it. Later Bob

   If you have any check valves or load hold valves on the rams this will also cause heat if faulty.
