Internship Life 8

Last week, My visiting supervisor came to Hitachi company and visit me. I went to Sunway pyramid meet him because he don't know how to come to Hitachi and luckily one of the student accompany him to sunway pramid. He meet my supervisor to know my current situation in the company. After that, he also ask me few question regarding to internship flow. Today, i learn how to dismate and assembly main pump, where the excavator depend on it to function their boom with hydraulic fluid. The problem for this main pump is because of unknown material or as we suspect is plastic that accidently throw inside the hydraulic tank and cause the main pump fail to function normally.
