sir bakit po kailangan pala i adjust yong pilot pump or charge pump?, at anu po ang sinusuplayan ng pilot pump or charge pump?? sana po mabigyan nyo ng pansin sir..tga subaybay po ako sa inyong video.tanx
Bro patolong naman yong hawak ko kasi na unit na zaxsis 200 "aging hinahangin palyado ang makina nya bro ano kaya ang prolema wala naman syang pitipom dayrek injecion sya bro
If it's an excavator you must check the restriction valve between valve bank and cooler. It's probably blocked. The restriction valve makes the hydraulic oil to go slowly to valve bank to cool down
Gud am. Ttanung lang pho...backhoe hitachi zaxis160 pina palitan ng taga hiitachi ng main pump, pinalitan ngaun iniwan, ng hindi nila mapa galaw. Anu po kaya ang trobol nun?
You can adjust the brake charge on the brake and pilot suplly valve to 120 bar. 60 bar brake for front and 60 bar for brake at the rear diff. Brake charge is the sequence valve situated next to pilot pressure relief on brake and pilot supply valve
But remember if you increase the brake charge the supply of oil to the fan is going to decrease. If brake charge is 120 and fan pressure is at least not 120 bar you must repair main pump
Boost pressure must be adjusted first at 350 bar and then main relief on 320 bar. Boost pressure you adjust on the front part of the main relief and main relief on the back side of the main relief valve. But before you adjust the main relief. Make sure your pilot pressure is 40 bar
sa pagkakaalam ko may solenoid yan para sa swing lock nasa bord ang swing sa left side may swing lock na nakamarka . may apakan din na switch nasa sahig check nyo lang muna mga wirings
Patolong Naman Po master. Myron KC kaming pinalitan .lahat Ng hydraulic hose . Tapos Ng kinabit nanamin ayaw komana lyong bakit at Yong trabil ayaw gomalaw Yong backhoo ano Kaya Ng yare .
Boss paki tulong Naman ohh. Ex200 Ang unit ko. Bagong overhull Ang ingene Koh !! Tapos. Nag over heat parin. Sabi nila pa balance daw Ang. Pressure niya.
Recondition mo na hydraulic pump mo boss,yan sintomas nyan sa umpisa malakas pag uminit na hydraulic oil humihina,sigurado may mga tama na nyan sa loob
Reseal mo pump mo kapag mainit na langis malabnaw na dahil sa mejo Malaki na tolerance Ng block at valve plate dun na lulusot Ang pressure kadalasan tstagas na Yan sa may main seal dahil overpressure na Ang case drain line.
@@glenquagmire4232 hydraulic oil viscosity is higher when oil is hot and thicker when cold. If pump weakens when oil is hot it means that the main pump is not supplying the right amount when hot. Replace pump
Wala kc kaming komatsu na unit bro,kung hnd gumana lahat,isa sa mga causes nyan sa safety lever dyan nkalagay sa left side mo sa operator seat tabi ng left joystick.ang pilot valve kadalasan may kasama accumulator yan,try mo check kung mag energized ang solenoid direct mo sa battery or cross check mo sa ibang solenoid pag palitin mo bro.
@@MotorkidMART malakas namn sir,kaso nka simi electronics na 2.pgnka andar na ung makina,open na rin ung PTO nya,kaso nga lng mahina sa boom-up,bucket at swing at pgpinilit q namamatay ang makina.
Boss pa tulong naman po.. Cat 320 ung unit na backhoe.. Malakas po ang rpm.. Pero hirap syang iboom up.. Humihina ang makina.. Boom up Lang po ang diperensya.. Pero ung I ang function OK naman po.
@@MotorkidMART ah..ok master..thanks.. Master ask ko lng.. Possible ba n kapag mataas ang pressure ng main pump..mas mataas s max.pressure...magkocause din b ito n pagkamatay ng makina if sagad na ang mga boom..
