How to check if plunger and barrel of a fuel pump is in a good/bad condition, and if we can use it for next running hours.10. Overhauling of fuel pump of A/E11. Fuel injector pressure testing and checks while testing.12. How will you come to know if nozzle holes of an injector is enlarged or not, I said one tool is dere, what is dat tool called, it is go, no go gauge.13. At what pressure Crankcase relief valve will open.14. Exhaust valve seat material and draw diagram of exhaust valve seating.

got mep

folks if you are going for first time please read the basic do not go for very high level. sir checked my written exam. i failed in MET and MOTOR so in the begning only sir told me you failed in met and motor so lets see saftey and mep. I would suggest you to concentrate more and more on subject you have passed. i was not sure about it and i concentrated more on motor and electrical, result i did not get safety. please do not do the mistake i have done and, ,,, nothing else .
