hi i recently bought a kobelco sk70 serial no 21076 with helicopter cab. now iv got problems with the hydrolics one side of the pump seams to be overloading. hence stalling the engine and making the machine unusable! has anyone come across this problem befor? or any idears on how to fix it?
Are you sure its the pump and not fuel problems,? i have a customers did the same it was bad fuel lines!
im sure its overloading one side of the pump as when you put a gadge on one side its full of pressure and the other side there is not pressure. if you work serton functions the engine the engine comes back to life.
Theres a guy on here called MR KOBELCO if you look him up and PM him i'm sure he can help you, he know his way around Kobelco hydraulics!
thank you cps iv just mailed mr kobelco
