What does it mean when an oil exchanger is overheating?

If the system is overheating, it means that either there is a problem in the cooling circuit or the capacity of the exchanger is insufficient for the ambient operating conditions. On the other hand, if the measured temperature drop across the exchanger is 10ºC and the design oil flow-rate is 90 L/min, the exchanger is dissipating 26 kW of heat.

A: Often this is due to a lack of pressure due to the transmission pump sucking air – cavitating. Low oil level? If any oil leaks are present, while machine is parked – these are usually leaks on the suction side of system & need repair.

What causes high pressure on a crawler loader?

I would first look at the relief valves located under the torque convertor housing. It is possible the one or more of the valves is sticking, causing the high pressure. The plungers/valve pistons should move freely in their bores. Thank you so much for the advise and I will check that out an then let you know what I find.
