Hey everyone I need some help can anyone help me identify the component creating this noise for me and the remedy I have 1999 Hitachi ex200lc-5 I have put a link to a youtube video so you can hear the noise it makes my skin crawl when I hear it. Any help would be greatly appreciated thank you.
Good day If it is only on the arm I suggest you split the arm cylinder and inspect Kind regards Uffex
Which control causes it
should be ease enought to find do one thing at a time by picture could be bucket cyl boom or stick do one at time should find where to start,or keep ruing what take long dont sound like.
There is a hose mounted on each pump that is dead headed and secured to a mount. I would check to see if one had broke loose from the mount or the mount is loose. That's what it sounds like to me.
We had this problem with the dash 1 when we replaced a pilot hose with a regular hydraulic hose it would make the most god awful sound when you used that function.When we replaced that hose with a synflex hose (all pilot lines are synflex) the noise went away.Also check the steel lines running up the boom that the clamps are tight.I had one service call where a guy had that same noise and I found he had laid his track shovel on top of the steel lines going to boom by the swing reducer. It only cost him $500 for me to tell him that.
Hey thanks for the help. So it does it when swinging the arm in or out more so when digging in harder ground i moved some loose dirt around this morning and it didnt choke up on me so I checked the lines up the boom 1 seems to have pulled about and inch and is leaking at the hard line that feeds the cylinder. I am going to replace it this week, question did you go to the dealer for the lines or get some made? I am considering replacing all the lines given that the machine is 21 years old and they are more than likely original lines.
Also if anybody can help me find hydraulic schematic for this machine I asked the dealer here Wajax and they dont want to give it to me apparently.
