here is the problem, the pressure of the shovel does not work on the right traction side it is slow as well as the digging it is very slow. the left side him traction is great the swing also remove the arm it's fine. the problem is intermittent. the shovel was normal and after three days of work the problem occurred. after three days of work even with this slowness the machine is back to working well and it lasted a few days .. now the problem has returned
Sany Sy210 21Tons 2008 3000H Brand new oil and filter the monitor has not worked since it was stolen.
Good day The symptoms are that of one pump loss, as it is of an intermittent nature the probability is more likely one of the check valves which connect the main relief is passing fluid under pressure. Kind regards Uffex
Good day The thread you posted is much better in the excavator section of the forum as I believe you have a Sany 210 excavator. You can check this out without to much trouble - raise the boom if it slows pull the arm fully in and hold it at that position. If the boom speeds up that has confirmed the cause of the problem. Kind regards Uffex
And what is a trouble ? the motor and turbo work good
One pump double ans 4100 PSI each, If I show you pictures can you tell me how to check?
Good day Sir As i interpreted from the post you are loosing power and speed on the boom the issue is intermittent also one crawler. Adding these events together appears to one pump dumping to tank. This can happen when the check valves that allow each pump to share the same main relief valve remains lodged open. You can confirm this sitting in the operators seat - raise the boom if its is slow fully stroke the arm cylinder if it recovers it will tell us it is the check valve. See attached Kind regards Uffex
Ok, the trouble not just the boom, its traction and boom down and bucket dig
Good day The recent post still can indicate a problem with the check valves, often the seat for the check valves is formed by the main body of the valve chest so be sure to check it also.Please try dead ending the arm, and see if the boom wworks OK. Kind regards Uffex
hello, for my excavator the monitor is not working because in the past it was stolen, with the new monitor and the new wire harness the monitor does not turn on. are you able to help me?
Good day sir I suggest you contact your local Sany service it maybe that your display requires a program if the attached fails to resolve the issue. Kind regards Uffex
It's a shame how some people don't listen.
