Question

Technician A says that the old gaskets should be discarded as they are removed from the transmission. Technician B says that the old gaskets should be saved to match with the new gaskets during assembly. Which technician is correct?A. Tech A
B. Tech B
C. Both techs.
D. Neither tech

Answer 1

Answer:

B. Tech B

Explanation:

Technician B is correct because the saved old gaskets will be used during assembly to match  with the new gaskets to ascertain that the new gaskets is original and of the same material quality with the old gasket. Also, buying new gaskets of the same specification with the old gaskets without having the old gaskets at hand will take a longer time to identify where there are many different types of gaskets that look identical.

Answer 2

Answer: The answer is tech A

Explanation:

A gasket is a mechanical seal i.e it is used to close up the gap between two mating surfaces when a fluid is to pass within and between the two components. Gaskets are very much required in systems that deals with high temperature and pressure.

Gaskets are made from cutting a material with yielding properties from the stock material. Gaskets are pre-designed, and component manufacturers also produce spares for replacement for machine users to purchase when the one in the machine fails. Technician B keeping the old old gasket for matching is wrong as you can purchase new gaskets with the required specifications simply by knowing the machine model and manufacturer.

Gaskets primarily fail by yielding beyond the required yield under load stress this can sometimes be due to human error by uneven bolt tightening during assembly or simply from working its normal lifespan.
