Hi ChidaYour testing procedures carried out are indicating that the hydraulic pump regulation may be an issue. You may need to remove the pump to inspect further if it is not possible to flow test the pump unit on the machine.Kind regards
Hello...Mr.Kobe Steel,Good Morning, Thankyou for you response, Tomorrow we are going to test Pump Pressures and I will come back to you Mr.Kobe Steel.Regards,
Please check pilot pressure. Check pressure before and after safety solenoid. Additionally, check voltage to safety solenoid. Good luck
Hi Mr.Kobe Steel,Good Morning,We have done Pump Pressure testing below as1)Servo/Pilot Pump Pressure Readings:in Idle--38Bars--while Working Pressure Readings--43Bars,2)Pump-1 Pressure:In Idle--No Pressure: While Working--10Bars & Some times reaching upto 100Bars,3)Pump-2 Pressure:in Idle Pressure reading--10Bars--While Working--20Bar,50Bars,150Bars & 200Bars, Some times 300bars, when its reaching 300Bars engine is struggling to run. All these Pressures are just will read within Seconds and will come down to 10bras, there is no constant pressures, We are getting these pressures while we are operating Boom, Stick & Bucket.We have checked regulators, Cleaned & installed as it is,Note: we have checked Pump Suction pipe & Strainer, Everything is Good,
Have you removed and inspected the contents of the case drain filter.
Hello... Mr.Funwithfuel,Good Morning,We have tested before as you said, May you help with other any Troubleshooting Methods please,regards
Pump 1 having no standby pressure is a big issue. More than just a pump regulator. That's what led me to ask about the case drain filter.
Mr.FunwithFuel,We did not check, We will Check & revert you soon,Regards
Make sure to pour out the contents into a clean bucket so that you can see what's in there. While you have it down, check the tanks return filter as well. Remove it and look closely in the pleats for metal, vinyl etc.
Hi...Mr.Funwithfuel,We have checked, Nothing is there, We did not find any metal files & Etc.

Once complete test pump pressures againI would recommend to remove the pump and inspect. Strip down and post pictures of internal components to help with inspection and repair.
Before you remove the pump please measure both P1 & P2 main and negative control pressures at the same time.The fact your engine is laboring indicates you have an engine issue or that the hydraulics are are overloading the engine. This may be in conjunction with a hydraulic issue, either pump output or regulation.I would like to know what your cycle times are for all functions but at a minimum left and right travel.
