Bobcat T770 Hluav taws xob teeb meem thiab tov lub bobcat yog ib overhead crane uas yog zoo meej rau lifting loads. Yog hais tias koj bobcat crane tsis ua hauj lwm kom koj yuav tsum tau coj nws mus rau ib tug tsim nyog thiab cov technician uas yuav tau paub txog qhov teeb meem thiab kho nws sai thiab npaum li cas. Lub bobcat cranes zoo paub tias hnyav-duty haujlwm.
Roj gauge tsis ua hauj lwm
Kuv muaj ib Bobcat T770 khiav skid steer thiab cov roj gauge tsis ua hauj lwm. Kuv muaj cov roj tank hloov, tab sis tus gauge tseem tsis ua hauj lwm.
Kuv hloov tawm cov roj sender chav tsev nrog ib tug paub zoo thiab thaum kuv tig rau qhov tseem ceeb nws nyeem yuav luag tag nrho, ces mus tas.
Excessive dub haus luamyeeb ntawm sab xis ntawm lub cav
Lub turbocharger yog thawj kauj ruam hauv ib saw ntawm components uas yuav ua rau pa luamyeeb. Cov huab cua filters, khib nyiab los yog actuator, exhaust manifold, thiab lwm yam components yog tag nrho cov kab nrog lub turbocharger. Ib feem ntawm ib qhov chaw no yuav ua rau muaj cov pa luamyeeb dub los tshwm sim.
Ib tug khib nyiab yog ib bypass rau exhaust gases. Nws pab tswj cov boost theem tau xa mus rau lub cav. Ntau dhau lawm los yog boost me ntsis yuav ua rau pa luamyeeb dub los ntawm cov kav dej exhaust.
Ib lub lim dej uas muaj cua phem los yog puas ua rau muaj teeb meem dub. Av thiab khib nyiab yuav clog ib pa cua, tiv thaiv kom tsis txhob muaj cua txaus los ntawm xeeb lub cav cylinders.
Cylinder #5 misfire code P0305
Tus P0305 code txhais tau hais tias cylinder 5 yog misfiring los yog randomly misfiring. Pib los xyuas rau intake leaks thiab yog tsis muaj leaks pom muaj cov kauj ruam tom ntej no yog hloov cov spark plugs rau cylinder 5. Yog hais tias qhov teeb meem persists ntxiv yuav tsum tau mus kuaj qhov teeb meem, saib "Tej zaum Yuav Ua Tau Kom Muaj".
Tus P0305 code txhais tau hais tias cylinder 5 yog misfiring los yog randomly misfiring. Pib los xyuas rau intake leaks, intake gaskets yog ua rau muaj ntau yam cylinder misfiring. Yog hais tias tsis muaj leaks pom muaj cov kauj ruam tom ntej no yog hloov tus spark plugs rau cylinder 5. Yog hais tias qhov teeb meem persists ntxiv yuav tsum tau mus kuaj qhov teeb meem, saib "Tej zaum Yuav Ua Tau Kom Muaj".
Ob wires rau lub injectors khiav rov qab mus rau ib harness
bobcat T770 ob wires rau lub injectors khiav rov qab mus rau ib harness. Ib hlau yog ib tug hwj huam 12-volt fais fab, thiab lwm yam yog av. Cov khoom siv ECM khoom siv 12 volts rau lub hwj huam txhaj thaum twg lub cav yog khiav. Lub ECM grounds lub injector thaum nws xav roj txhaj rau ntawd cylinder. Yog koj tsis muaj voltage, koj muaj ib qho teeb meem nrog koj wiring los yog ECM.
Tus txhaj muaj ob wires vim hais tias nws yog ua tau ib electromagnet. Thaum 12 volts yog thov kom tus txhaj, nws tsim ib magnetic teb uas kaw cov valve hauv lub injector thiab tso cai rau pressurized roj los spray rau hauv lub cylinder. Thaum tsis muaj voltage yog nkag, yog tsis muaj magnetic teb, ces tsis muaj roj yuav spray.
Tus connector yuav tsum tau txiav thiab ib feem ntawm nws yog uas ploj lawm
bobcat T770 The connector twb tau txiav thiab ib feem ntawm nws yog uas ploj lawm thaum kuv yuav nws. Lub tshuab muaj ib pin nyob rau hauv lub rooj zaum rau tej thaj chaw deb hydraulics thiab tus txiv neej kawg yog nyob rau hauv lub dash ces yog cuab kev tias tej yam yuav tsum tau raug tshem tawm kom lub tshuab tsis ua hauj lwm nrog ib trailer.
Kuv muas ib tug tshiab tswj valve los ua ke thiab plugged nws nyob rau hauv. No mas, ua hauj lwm zoo tab sis yog tsis muaj wiring diagram rau lawv. Kuv yuav tsis nrhiav dab tsi hauv internet los yog nyob rau hauv kuv kav manual yog. Kuv yuav tsum paub tias wires mus qhov twg thiab seb lawv hook tuaj ces kuv yuav siv no circuit court nrog kuv trailer.
Cov roj gauge qhia tas thaum nws muaj ib daim ntawv qhia txog tank
Cov roj gauge sender nyob rau hauv lub tank roj tank thiab yog txuas nrog cov roj twj tso kua mis. Nws kuj muaj ib ntab uas txav nrog cov roj theem. Raws li cov ntab dauv, lub teeb liab hluav taws xob yog xa los ntawm cov resistor rau lub gauge.
Cov roj gauge sender yuav muaj ib tug hlau txuas nrog nws thiab yuav muaj ib tug av hlau txuas. Hauv pem teb hlau thiab xa hlau yuav tsum tau disconnected. Siv ib lub teeb rau ob wires thiab xyuas cov hwjchim thiab hauv pem teb.
Yog hais tias muaj hwj huam rau ob wires, ces koj muaj ib tug phem sender nyob rau hauv koj lub tank. Yog hais tias tsis muaj hwj huam rau xws li hlau, tej zaum koj yuav muaj ib tug phem ignition hloov los yog ib qhib circuit court hauv koj wiring harness ntawm tus sender thiab cov dashboard.
Peb hloov cov roj theem sender thiab uas tsau qhov teeb meem
Teeb meem nrog bobcat T770 roj gauge. Tus gauge yog nyeem cov roj yog hais txog ib nrab tag nrho txhua lub sij hawm. Thaum peb muab tawm chav tsev xa, nws yuav tsum tau leaking roj thiab muaj ntau khib nyiab nyob ib ncig ntawm nws. Peb ntxuav tawm cov roj tank thiab ntxuav tau xa chav tsev xa thiab muab nws rov qab rau hauv. Qhov teeb meem txuas ntxiv mus. Peb hloov tus sender nrog ib tug tshiab thiab uas tsau txhua yam. Ib txhia hais tias koj tsis tau hloov chav tsev xa, tab sis peb puas tau vim muaj tug tsis muaj txoj kev los ntxuav nws kom zoo nrog tag nrho cov nooks thiab crannies nyob rau hauv nws.
Tom qab ib co kev tshawb fawb, peb nrhiav tau qhov no yuav yog ib qho teeb meem heev nrog Bobcats hauv no koob
bobcat T770 tom qab ib co kev tshawb fawb, peb nrhiav tau qhov no yuav yog ib qho teeb meem heev nrog Bobcats hauv no koob. Qhov teeb meem yog tshwm sim los ntawm tus Disease fact tias cov solenoids uas tswj lub 2-speed mus txawv tebchaws yog txuas ncaj qha mus rau lub roj teeb thiab yuav tsis fused hlo. Qhov no ua rau cov wires melt ua ke thiab luv luv thaum lub hwj huam yog rho tawm hauj lwm. Thaum lawv twb melted lawv tso tseg tsis ua hauj lwm thiab koj yuav tsum tau hloov lawv. Qhov xwm zoo yog tias nws yog ib qho yooj yim kho thiab tsuas yuav siv li 30 feeb kom tiav.
Tus txhaj tsis firing tab sis tsis muaj hwj huam yog xeeb nws, ces nws yuav tsum yog tus wiring harness los yog computer yuav ua rau qhov teeb meem
Tus txhaj tsis firing tab sis tsis muaj hwj huam yog xeeb nws, ces nws yuav tsum yog tus wiring harness los yog computer yuav ua rau qhov teeb meem. Ib mechanic muaj troubleshoot no.
Injectors muaj ib zaug xwb hluav taws xob sib txuas rau mov roj thiab ib ob hlau uas saib siab nyob rau hauv cov roj kab. Tus txhaj tshuaj yuav muaj ib tug seep los yog leak uas tso cai rau roj khiav thiab tso cai rau huab cua rau hauv kab. Cov huab cua npuas ua lub siab nyob rau hauv cov roj kab nco, uas triggers cov lus ceeb toom teeb rau lub dash. Lub teeb tshua illuminated mus txog rau thaum lub siab mus txog ib theem uas indicates muaj tsis muaj leaks los yog seeps.
Tus txhaj kuj yuav clogged vim dej los yog lwm yam txawv teb chaws nyob rau hauv cov roj kab. Nws tseem tau tias tus txhaj yog qhib, uas muaj ntau zog txaus los ntawm nws thaum tsis muaj siab thiab ces kaw thaum muaj siab. Thaum zoo li no, koj feem ntau pom ib qho nce rau hauv roj noj.
Nws tseem tau tias muaj kev puas tsuaj rau ib lub wires hauv lub wiring harness, uas tej zaum yuav tsum tau ib qho kev soj ntsuam ntawm txhua hlau thiaj li yuav nrhiav tau nws.
Peb kuaj rau cov hwjchim ntawm pin 5 ntawm ob injectors (hwj huam yog nkag ntawm "F") thiab nrhiav tau ob leeg tau lawv xav tshuaj
bobcat t770 peb kuaj rau cov hwjchim ntawm pin 5 ntawm ob injectors (hwj huam yog nkag ntawm "F") thiab nrhiav tau ob leeg tau lawv xav tshuaj. Qhov kuj ntawm tus thawj winding yog 0.5 ohms thiab cov kuj ntawm cov theem nrab cua yog 5.6 ohms. Ob leeg nyeem ntawv yog tsis pub dhau Bobcat specification.
bobcat t770 peb ces ntsuam xyuas rau cov hwjchim ntawm pin 8 ntawm lub injector (hwj huam yog nkag ntawm "G"). Tsis muaj hwj huam yog tam sim no nyob rau tog twg txhaj. Peb twb tsis siv rov qab mus pin 35 ntawm lub computer, uas yog qhov twg "G" tau nws cov mov voltage thiab nrhiav tsis muaj hwj huam muaj. Peb mam li ntsuam xyuas rau cov hwjchim pin 2 ntawm lub computer, uas yog ib tug liab hlau uas khoom siv no circuit Court nrog 12 volts thiab nrhiav tau nws muaj 12 volts tam sim no. Qhov no txhais tau tias lub computer yog grounding no circuit court thaum nws yuav tsum tau energized.
bobcat t770 siv ib scan cuab yeej peb commanded lub computer los energize no circuit court thiab nrhiav tau nws puas tau li ntawd, uas paub tseeb hais tias peb qhov teeb meem yog nyob rau hauv lub computer.
