Last time, I changed the cylinder gasket privately and replaced a pile of 12 failed top cylinders. I purchased a new set of top cylinders and spent a few hundred yuan. Now I have time to calm down and study the failed top cylinder and found that it can be repaired. It is still very simple, you don’t have to spend that money. The following is to express it by looking at the picture:

For the 12 replaced ejector cylinders that failed, press the concave end of the ejector cylinder, and there is no elasticity at all

Break it down! Point-tipped tweezers jump out of this spring (circlip)

Then remove the inner accessories in order (wd-40, gently tap, the inner cylinder has an eye to help) to clean up a lot of damage

Clean it up, clean it, lubricate it, add some new oil, and then reverse the process of installation and restoration
