Hello. Your video extremely useful. I suspect some kind of problem like that on my Komatsu excavator . I got some fluctuations at the max pressure. When I shut down the machine I’ve got a shock on the joysticks. I will check how this valve is inside. Your information is extremely valuable, no one else would tell 👍
bro try this idea, start the machine and switch the the safety lock then, if you are alone you have to go down then check the rear side or the hydraulic pump there is a 2 solenoid coil over there, what to do,must be both solenoid is in powered meaning have 24volts supply ok, but when you fully operated or work the machine one of the solenoid is automatic of, and the other one will conteniou on ok, or if you have watsapp give me i will try to send you the picture of hydraulic pump were to locate the solenoid
bro as you requested i made 1 video i think this is the solution in your problem try to follow my video for the proper way on how to check ok, and i hope you share my video and let somebody to subscribe, thank you for watching
I'm looking at buying a komatsu PC 220 lc3 series excavator I'm curious I'm glad your advice is on it if it is a good and reliable model thank you and also what I should look for when looking at it
bro if you have watsapp add me and show me the photo of machine and sr# +971567581176, test the machine idle full boom up 10sec.dont release the pilot and hear the sound of engine also arm same procedure observe if engine is not almost stop most be engine will be run only like idle, and full acceleration check the speed of boom, arm and bucket, up boom close of arm and bucket and boom up out arm and bucket, to make it sure that there no any enternal problem, sometime, you very attrac visual outer of the machine but maybe and you do not know that there is or you cannot see what we have or weak enternal problem
@@caterpillarjhunhunk i sir, i have a pc200 lc3 1987 serial 26772 and i think may be a have some kind of problem with one of these cause at hi rpm the lower the boom fonction become realy stiff like it have hi pressure comming in the low pressure side
forgot to mantion that i like your video thx a lot for shearing good video that have a lot of rare an awsome info i'm from quebec canada keep on going sir 👌💪
Hello ! I have looked at my relief valve and unfortunately it doesn’t have defective seal as yours. It has no seal in fact. On this machine I have a problem at the drive. It definitely have low driving force, After actuating it in slope for some time it completely can’t move. I have included the videos, main puppet and main relief valve and a try of machine. I have installed analog indicator that tells real time the pump pressure, it’s parallel to the motor on the original pump pressure sensor, I find it very handy (was not able to enter the reading of pressure on machine monitor) Puppet close view : th-cam.com/video/D_uCgDHvFiY/w-d-xo.html Main relief valve : th-cam.com/video/sT6mJDjbGGw/w-d-xo.html Hydraulic motor stalled rexroth a6vm : th-cam.com/video/UCaKybxkVXc/w-d-xo.html
Salamat sa tulong brd un 138 kasi na ginagawa dati mahina lahat pero nung nagpalit ako ng redusing valve lumakas pero ngayon pag uminit hirap un makina pero pag ginalaw ko un baket in or out gumanda ang andar ng makina
Ung hydrulic poh ..Hindi nya mataas ung boom up nya kapag may karga na ung bucket nya kapag naka powermode sya ...pero Kung naka low mode sya kaya nman nya itaas ung boom up sya sir..
Pero kapag sinagad mo ung rpm nya kaya nman nya itaas ung boom up khit may loud ung bucket nya pero may lumalabas na code sa monitor na E15 sir ..at ung code na un sir eh over rpm ..

Do you have more videos on komatsu excavators
thanks for watching, bro tell me what type of video electrical or mechanical
Hi thank you for the video what is the komatsu code to access the monitor to see pressure

Idol sa pc138 ba ganyan din ang main releiif valve niya
palagay ko brad magkaiba, wala kasi kaming ganyan size ng machine, pero s sistema ng pagrrepair halos iisa lang
Salamat sa tulong brd un 138 kasi na ginagawa dati mahina lahat pero nung nagpalit ako ng redusing valve lumakas pero ngayon pag uminit hirap un makina pero pag ginalaw ko un baket in or out gumanda ang andar ng makina
Tanung lang paps ung ung pc 228 sir ..kapag naka Low mode sya ok nman ung false..pero kapag naka powermode kulang ung lakas ng backhoe sir
sinsya n now lang ako nka reply, alin b ang nagllow power makina b o sa hydraulic system
Ung hydrulic poh ..Hindi nya mataas ung boom up nya kapag may karga na ung bucket nya kapag naka powermode sya ...pero Kung naka low mode sya kaya nman nya itaas ung boom up sya sir..
Pero kapag sinagad mo ung rpm nya kaya nman nya itaas ung boom up khit may loud ung bucket nya pero may lumalabas na code sa monitor na E15 sir ..at ung code na un sir eh over rpm ..
