Replacement of 140 Breaker Hammer Frequency Regulating Valve Seal Ring

Hello everyone, I recently noticed during routine inspection that the breaker hammer frequency modulation valve was leaking oil. I happened to have some time today, so I replaced it.

Remove the screws, small screws are easy to handle!

Prepare 8 Allen wrenches, and be careful not to get the screws dirty.

The seal ring in the picture is obviously aged and damaged.

The frequency regulating valve is taken down and the sealing ring is ready to be replaced.

Done! At this time, it is not debugged yet. Just adjust the frequency manually after installation. I wish all my friends a prosperous business and a lot of money. I hope we will see you again.
