    Good video, the "Washer A and Washer B" or the Black "square packing" and the white "backup washer" are the primary sealing device. The external seal is basically a dirt seal. As you mentioned, anything that gets past washer a and washer b goes back to the transmission. If washer a and washer b get wore out they will leak and overcome the external dirt seal. The dirt seal is not made to hold the full pressure inside the pump. Something else to check is the drain line that goes back to the transmission sump can sometimes get plugged causing the dirt seal to fail as a small amount of leakage is expected past washer a and washer b. Also I noticed your dime valves showed quite a bit of wear, the ones sitting on the rear plate. Those are cheap and easy to replace. Like you said, many times the main bearings and races do not need to be replaced. Good work, keep it up. Also good english, easy to understand. God Bless

      One of the best comments 👍 Thank you so much for your time, I am sure lots of people will appreciate it as much as I do. With the valves , I couldn't find the tool to get it all done. Any advice or video will be greatly appreciated. I am planning to restore this great backhoe.

    Do not spin a bearing like that
    If you want to inspect the bearing thek the outer ring
    If it have a dul and not shiny surface or is steaky replace it

    How does the pressure limiting system keep the pistons off the cam? Does the pressure compensating (relief) valve feed oil pressure to the pump case?

    I loved the video as I am about to tackle a leaky pump myself. I am curious how did you press off the bearings with that cam in the way?

      I used a press and bearing puller set from Amazon, but I should have gotten bigger one from hurbor freight lol.

    Great video. Did the new bearings fix the noise issue?

      It's day and night. It sure sounds healthy now. I would say not as horrible noise. Its loud when it's brand new. I believe it's normal , but it doesn't punch you in the years anymore.

      @@colossus5752 awesome. I’m rebuilding a pump from a 4020 right now. It has the same issue as yours with the pitting on the cam portion of the shaft. Waiting on a new shaft and bearings now. Thanks for the video.

    Was wondering what model machine it came off of. I have a slightly different hose location set up and am trying to figure out a different problem. But will be doing going through it the same as you are. Did your noise go away or get better when you used a hydraulic function?

      It's 310a and it was green color before =(farm) it's definitely more Quiet now and I am not as worried about it anymore. Just make sure it's all done by the book (end play and other things like that) once you will have it all on the table , the pump shaft will tell you what you need to get. You will see the difference. Good luck on your project.

    Great vid! What tractor is this out of? I just bought a 300b and can hear a bad bearing sound (growl) from the pump area. What kind of noise was yours making?

    • @colossus5752
      @colossus5752  3 роки тому +1

      Probably the same bearing noise. But it's a 310a john deere
