Hi master for cubota kx 121 2 where is located reliv valve presure for gjystix thancu for your video

I have a 228lc-3 Komatsu and I can not get it to work right I put the two selonoides at the pump but still the engine wants to die as soon as I touch the stick to move it what could’ve .
Bro try to contac me in my whatsapp +971567581176, i need more details of your machine send me some videos on actual and some picture of pump and control, and also engine if you can ok i need to by my self about your machine
You were not getting normal pressure in the past after adjustment. Then later in minute 20 you got the normal pressure 370.
My question is was the problem because of relief valve which you replaced? Another question is if 1 relief valve is damaged it will affect pressure reading on the second relief valve because in the start both 011 & 012 was showing 330 pressure
Thanks for the beautiful video
thats the good question this machine or komatsu machine once did you operate by functioning the whole system, you know this machine they have a merge divider to function the main pump individual or merge the supply at a time, to provide the full pressure of the front and rear pump in direction, the problem is why i replace the upper main relief valve its already full tight so no chance to raise the pressure i think it is have enternal leak, because after we replace the valve everything its become normal,there video it real happen in our actual trouble shooting, and theres no any hidden adgenda, it is actual.
Hello..
Is the relief valve o ring is damaged?
for what machine you have
Comedic relief valve was leaking? ;-P
ser have a good day i have a troble lonking xcavator the swing is very weak. and the lift travel motor is not travel ... how gana do

sir can i ask about hydrolic oil. can engine oil use as hydrolic oil to komatzu pc 220. because my friend from abrod advice me to use engine oil instead hydrolic oil. now my bachoe is n trouble.

@@caterpillarjhunhunk kahapon may pinalitan akong hose kasi pumotok. pagkatapos ginamit ko ng sandali ok naman ang kilos nya. kanina nag dagdag ako ng langis kasi ang daming nawala kahapon nong pumotok ang hose. nag dagdag sko ng dalawang containers ng 15w40. umpisa ok nan ang kilos nya,tapos bigla nalang bumagal lahat ng function nya sir. ano kaya ang problema nito sir. may kinalaman ba ang battery kasi nag error ang battery sa display.
Sir Ang implements ba o control Ng komatsu ay Yung kaliwa ba ay pump1 at Yung Kanan ay pump2 kagaya din ba sa controlvalve left is pump1 at Ang right pump2? Salamat sa feedback godbless
sinsya now lang ako nagreply,about sa left or right ng pump pra sa caterpillar yan,sa komatsu ay front at rear,ang komatsu dalawa ang pinaka main relief valve nya,unlike sa cat isa lang sya,pero ganun paman may mga relief din ang bwat function sa control valve at iba pang attachment for the safety ng machine.
sir ask ko lng po,yong pc 220 din po d2 pagsabayin ang boom up at steak in huminto ang boom up ang hina ng steak in,,ganon din pag boom down at steak out,,pro pag d mo isabay ok nman ang galaw ng isat isa,,anu kaya dahilan sir,,sana po mapansin nyo po ang katanungan ko.maraming salamat po.
E check nyo muna ang main pump pressure, baka ksi isa dahilan nya eh mahina ang pressure ng isang pump bka kya sya mahina
Good afternoon boss Tanong kulang kung may mabibilhan ba Ng repair kit Ng control pc228 -5 tsaka pump Ng cutter pillar a200b main pump salamat sa magiging tugon
Kung repair kit meron nyan iwan lang kung available s mga supplier
Wala kasing available Dito sa manila mga oring lang Meron ,mga sealing ang Wala baka Meron Ka baka pwedeng makabili Sayo pati Yung laman loob lang Ng bomba Ng cutter pillar o kaya may assembly Ka Jan pag Meron boss pa presyo Ako kung kaya salamat sa magiging dugon boss
Problem boom up sir! Padelay delay yung taas
sir kung pamilyar ka s pagccheck ng pressure check nyo muna, kung un balance ang pressure kailangan balansihin then ska testing, kpag ok n pressure pero ganun pa rin, ung valve n nsa likod ng control valve merge divider ang tawag doon sa bandang kaliwa kung nsa ilalim k ng makina nkaharap k s control valve may makikita k n relief valve doon try mo hapitin or higpitan tapos testing
same lng po ba sya ng pc30 mr thanks
Sir i have a problem about excator komatsu pc228us.slow boom up while the other is ok sir.boom up only sir.thank sir.
sir sa pc 200 komatsu ng kaibigan ko pag umunit na humihina ang travel at boom....ano kaya ang problema?
kailan kya huling nagpalit ng hydraulic oil yan, ppwede kya sya nahina dahil nagllow pressure, or mahina talaga ang pressure ng isang pump mo ung nagddrive pra gumana ang travel motor mo, pressure test kyo s pump, kpag nagttravel ksi individual n gumagana ang pump pra s travel motor, paanu dahil may merge divider yan at sya ang nag hhiwalay s pressure ng pump papunta s travel motor, ngayon kapag ang travel ay mahina ang isang side, posible n mahina ang isang pump, ppwede dahil s main relief valve, meron ako video tungkol s main relief valve kung paanu ginagawa ko para maibalik ang tamang pressure
Pc200-7 overheating main pump hydraulic alarm on unit no power tnx
sir sinsya n hindi ako makasgot s mga nsabi mo,d ko alam kung ano mga pangyayari, pero kung over heat ang main pump ppweding over pressure or over used n hydraulic oil mo or ung cooling system mo gaya ng fan baka barado n ung dinadaanan ng hangin nsa harap ng radiator ng makina yan may time ksi n hindi n nahihigop ng fan ung init ng oil cooler, pweding ganun, or check nyo rin ung mga suction hose nyo bka lumiit n butas or namaga n loob hindi n makahigup ng normal ang main pump,. contakin mo ako s whatsapp, +971567581176
Kabayan may ginawa ako dito sa pinas pc120-6, nagpalit na ako ng main pump at pcv valve controller, ang problema pag mainit na humihina ang operation
Ang tanung alin ang humihina basi s observation mo makina o hydraulic system
@@caterpillarjhunhunk hydraulic system, bago na ang packing seal ng swivel ang travel.
Yong travel unang humihina kaya nagpalit ako ng bagong packing seal
Hellow sir gud evning may kumatsu kami pc220-7 d na gumagalaw ano mo trouble
d ko maintindihan kung paanung d gumagalaw, o mahina gumawala paanu b? ksi d n talaga nagalaw or tagala wala sya paggalaw kahit kaunting kaunti, bka nman wla supply n npasok s ppc lock nya, yan ppc lock n yan yan ung kpag mag ooperate kna ng machine nsa left side kpag nkaupo kna s upuan, check mo un bka pumutok ang fuse
Anu po ideal na pressure sir?
s main pump 350 t0 370
Pc300-7 Boom cylinder pressure check video plese send me
Boom not Jacob wahat problem
@@maridimohanrao649 bro contac me in my whatsapp +971567581176,give complete details of problem ok video or photo
Sir bakit marina magtravel Yong backhoe pc200-6 lc
sir check mo pressure ng main pump para malaman mo kung ang main ba ay nasa tamang pressure
Sir pwdi magtanung sir sau anung dahilan kaya sir bakit agad umiinit na ang hyrudlic oil kahit kunting gamit palang Ng backhoe
maraming pweding maging dahilan yan pweding luma n ang langis mo or halos wla ng viscosity langis, at ppwede rin n over pressure, o kya brado n ang oil cooler mo, mas the best is gumamit kyo temperature gauge pra sure, baka ksi hindi n accurate ung self gauge ng machine, at ppwede rin namamaga n ang loob ng hose lalo n ung suction line, anu ng naoobsebahan nyo s machine kpag mainit n ang hydraulic oil nya.
@@caterpillarjhunhunk ah ok sir sira pala ang pump kaya pala mainit maxado hyrudlic sir pero ang problema naman ngayon sir nag estock up mga soliniod anu sir Anu kaya dahilan pati solioniod sa pump sir stock up
Sir pwede patulong sa pc200-7 nmin
Trouble nya sir nahihurapan po makina nya.
brad n e check nyo nb ung solenoid n nka attach s main pump dapat ung isang solenoid na nkalagay s bandang gitna ang permanent ang power supply noon tpos ung nsa bandang loob kpag nagoperate k ng machine magooff un,check nyo nlang muna
Sir my Facebook po kayu
What is your fb accont sir
Hello, nice video. But I’ve got a question for you: how do you know it’s the overpressure valve that release too early / have internal leak ?
It could be as well the pump wear ?
My excavator is pw130 (wheeled machine but same pump than pc130)
When starting cold I can reach full pressure without problem (345 bars)
But if I insist at reaching 345 limit (it’s necessary when traveling on steep slopes) it will soon decrease the pressure and cannot reach 300 or less.
Machine has only 4000 hours, I’m going to rebuild the pump.
Already opened the main overpressure valve, but found nothing special.
Pump is single on this machine. Pistons / cylinders have no wear. Distributor plate have slight wear, swash plate (variable cam) have wear at pressure areas I’m replacing it.
It is possible the main valve getting hot then leaking so much ?
bro contac me in my whatsapp +971567581176 ok
Sir pwede k b matawagan s messenger mo

oh yeeh
Can i have your number sir? How can i ask excavator problems from you?
