I have recently taken hitachi landy 60-1 - 2007 december model. When the starting, the hitachi getting temprature 100 degrees within 20 minutes. We have checked engine, head and hydraulic problems, but no one mechanic could not solve this problem. Please help us
Have you checked the themostat?
yes, we have checked thermostat and engine head, bosch pump, hydraulic pressures etc.,
Do you shut if off at 20 minutes? or will it cool down if you idle it, and keep working? Have you checked the condition of the coolant? Belts tight? What did the inside look like when the thermostat was out? Can you see through the radiator to see how clean it is? Have you checked the radiator inlet and outlet temperatures? Sorry for so many questions, but you got to start somewhere.
