Akuyomfihlo ukuba xa uxinzelelo lokutsha luphezulu, kubaluleke kakhulu ukuba intloko yesilinda iphumle kakuhle kumphezulu wesilinda. Ngoko ke kubaluleke kakhulu ukukhetha uhlobo lwezihlangu zentloko othembela kuzo ukuze ugqibe umsebenzi.
Nokuba unelori yokusebenza esebenza imini yonke, ilori eyakhelwe umsebenzi oguquguqukayo, okanye into ephakathi, akukho mathandabuzo ukuba zonke iilori ziya kuxhamla kwiseti entsha yeebholiti zeentloko zesilinda.
Xa kufikwa ekuthengeni izibophelelo zenjini ezifana nee-stud, sele ziphezulu kuluhlu – i-ARP. I-ARP ibikho kangangeminyaka engaphezu kwama-50 kwaye, ngenxa yembeko yayo, iyaqhubeka nokuzama ukuvelisa izibophelelo zokusebenza okuphezulu kwiimfuno ezifunwayo. Nangona kunjalo, ukhuphiswano kweli candelo luye lwanda kutshanje kwaye enye yeenkampani ezikhuphisana ngesabelo semarike yiGator Fasteners, uphawu lweKT Performance oluvela eGroveland, eFlorida.
Akuyomfihlo ukuba xa uxinzelelo lokutsha luphezulu, kubaluleke kakhulu ukuba intloko yesilinda iphumle kakuhle kumphezulu wesilinda. Ngoko ke kubaluleke kakhulu ukukhetha uhlobo lwezihlangu zentloko othemba ukuba ziya kuwenza umsebenzi. Kutshanje sithethe ne-ARP malunga neemveliso zabo ze-head stud kwaye sithethe ne-Zeigler Diesel Performance eCanton, eOhio malunga neziqhoboshelo zeGator ukuze ufumane iinkcukacha zamva nje ze-stud kunye netekhnoloji yenkampani nganye, kunye nezinye izinto ezifanayo kunye nomahluko onxulumene nazo kwisihlwele sedizili.
Ngokwesiqhelo, i-fastener yefektri namhlanje si-fastener ye-yield strength elahlwayo. Oku kuthetha ukuba ngokuhamba kwexesha kukho ithuba elikhulu lokuba uya kuyiphakamisa intloko ye-cylinder kwibhloko kwaye wonakalise i-gasket ye-cylinder head. Ii-bolts ze-Aftermarket ezivela kwi-ARP okanye kwi-Gator Fasteners azoluli njengee-bolts zefektri kuba azinawo amandla e-torque yield.
“Ngokuphathelele ukusebenza kwedizili, sidla ngokugqwesa izixhobo zasefektri ngama-20 ekhulwini,” utshilo uChris Raschke we-ARP. “Leyo yayiyeyona nto yayijoliswe kuyo kwaye yayinjongo. Sasifuna nento enokusetyenziswa kwakhona. Uninzi lwabantu esathetha nabo basebenzisa izikhonkwane ze-ARP2000 kunye ne-625.”
I-ARP inikezela ngee-head bolt kits kwiinjini ezahlukeneyo zegesi kunye nedizili, kwaye izibophelelo zeGator zikwahambelana namaqonga amakhulu eenjini zedizili. Nangona kunjalo, iGator ayibonakali ngathi ikwicala legesi kwimarike, kodwa iza nokhetho lwe-LS head bolt.
Kwiinjini zedizili, iibholiti zeGator zenzelwe iinjini zeDuramax zowama-2001 ukuya kuthi ga kwinjini ye-L5P ehlaziyiweyo ka-2020. Iinjini zePowerstroke kunye neCummins ziqala kwiRams ngo-1989 ukuya kwiPowerstroke ngo-1994 ukuza kuthi ga kulo nyaka.
“Ii-Gator mounts zibukeka zintle kakhulu xa zithelekiswa noko ndikubonileyo,” utshilo uJustin Zeigler weZeigler Diesel Performance. “Ndizibonile ezinye ii-stud ezingathandabuzekiyo ezivela kwabanye abavelisi. I-ARP ibisoloko izisebenzisa ngaphezu kwakhe nabani na omnye. Nangona kunjalo, ndicinga ukuba ii-fasteners zeGator ngokuqinisekileyo zilukhetho olufanelekileyo kwaye lukhetho olufanelekileyo. Ndiyawuthanda umgangatho, ixabiso kunye nokufumaneka kwazo. 'saw.'
Njengoko zinamandla okutsalwa angaphezu kwama-220,000 psi, izibophelelo zeGator azizukunwebeka njengeebholiti zasefektri. Zenziwe ngemisonto egoqwe emva konyango lobushushu ukuze ziqine kakhulu. Zingamhlaba ongaphakathi ukuze ziqine kwaye ikhithi nganye ibandakanya intsimbi yechrome ephathwa ngobushushu, amantongomane angomhlaba ayi-12 kunye neewashers ezine-black oxide coating ukuze zihlale ixesha elide.
Nangona iGator njengophawu olutsha inokubonelela ngemveliso ekumgangatho ophezulu ngokwendalo, isenayo enye yezona zinto zibalaseleyo nezibalaseleyo ze-ARP - amava.
“Sisebenzisa i-torque tensioner ukujonga izibophelelo zefektri kunye nendlela yokufakela ifektri ukujonga imithwalo yokubambelela oyifumanayo kwizibophelelo zefektri,” ucacisa uRaschke. “Yiloo nto sakha ukusuka apho. Sikwanayo nesixhobo sovavanyo lobushushu, esisitofu esinegumbi lovavanyo ngaphakathi, kwaye ungafudumeza yonke into ukuya kuthi ga kubushushu bokusebenza kwenjini ukuze ubone ukuba ichaphazela njani izibophelelo kubushushu bokusebenza. Xa senza izixhobo zokubopha kuyo nayiphi na indlela, kufuneka siqwalasele ezi zinto. Sinezixhobo ezininzi kwibhokisi yethu yezixhobo zokwenza oko sikufunayo.”
Izibophelelo ngaphambili bezisebenzisa izinto ezingama-8740 kwi-180,000-200,000 psi, nto leyo ebisoloko yanele ukutshintsha izixhobo zasefektri. Namhlanje, iimpawu ezifana ne-ARP zinika abathengi ukhetho lwe-ARP2000, Inconel okanye iCustom Age 625 PLUS enamandla aphezulu okutyhala.
“Ngezixhobo ezingama-8740, unokusingatha kuphela malunga ne-200,000 psi, emalunga ne-38-42 kwisikali seRockwell, kwaye kulapho ulonwabo luqala khona,” utshilo uRaschke. “Ukuba uzama ukuyiphakamisa phezulu, uya kudinwa ii-headpins. Kuya kufuneka ukhethe izixhobo ezisebenza apho kufuneka zisebenze khona.”
I-ARP 2000 iqhube kakuhle kakhulu kwi-220,000 psi kwaye, ngokutsho kukaRaschke, yayiseneempawu ezintle zokudinwa kunye nokuguquguquka okuhle kwimithwalo ephezulu ye-clamp. Ukusuka apho, i-ARP inikezela ngezixhobo zayo zobudala ezenziwe ngokwezifiso.
“Enye yezinto ezintle nge-Custom Age kukuba yinto yentsimbi engagqwaliyo engayi kugqwala,” utshilo uRaschke. “Inamandla aphezulu okutsalwa (260,000+ psi) ngoko ungayishukumisa kwaye wonwabe. Yintsimbi engagqwaliyo nayo, ingxaki ngeedizili kukuba zinobushushu obuninzi, ukufuma, ukukhupha umsi – yiyo loo nto “Akufani nakwizixhobo zentsimbi ngokubanzi. Ukugqwala kukhupha i-hydrogen, kwaye ukugqwala kwe-hydrogen kunokonakalisa izibophelelo. Ukuba uzifudumeza kakhulu izikhonkwane ukuze ziqine, uya kuba nokugqwala okubangelwa kukugqwala. Amathuba okuba iingxaki zokugqwala kwe-hydrogen ziyaphindaphindeka.”
Kakade ke, ayizozinto kuphela ezichaphazela i-spike efanela iimfuno zakho, kodwa nobukhulu bayo. Ngokubanzi, ii-head bolts ze-12mm zingasetyenziselwa uninzi lwezicelo zeCummins. Nangona kunjalo, abanye abantu abasebenza kakuhle kakhulu banokusebenzisa ii-studs ze-14mm, ii-studs ze-9/16, okanye ii-studs ze-5/8.
“Kwiimeko ezininzi, zonke iiCummins zakho zasefektri ziya kuba zii-studs ze-12mm,” utshilo uZiegler. “Kwihlabathi lokubaleka, besisoloko sisebenzisa i-14mm okanye i-9/16 ukuze sifumane i-torque ephezulu. Iibholithi zentloko kwimoto yam yomdyarho zi-torque ukuya kwi-250 ft.lbs. Ezo 12mms zii-125 ft.lbs. Umahluko omkhulu ekubambeni, kodwa kukwasetyenziswa ngendlela eyahlukileyo kakhulu.”
URaschke uthe abantu abaninzi eCummins baqalise ukugrumba ii-stud ezinkulu kuba nje babengenazo izixhobo eziqinileyo ze-stud ezaneleyo ngaphambili. Ngoku, ngenxa ye-ARP, bakwenzile oko.
“Nangona abantu besafuna ukusebenza ngeebhloko, sibanika izinto ezikumgangatho ophezulu,” utshilo. “Isisombululo sethu sidla ngokwenza izibophelelo ezikumgangatho ophezulu ezisetyenziselwa ifektri. Ukuba ufuna ukutshintsha into ethile, isebe lethu leengcali liyaphambana. Sisebenze kwiimoto ezininzi ezahlukeneyo zedizili. Abavelisi benza oku, umzekelo, iShade, iHeisley, iWagler kunye nezinye”.
Nangona ngamanye amaxesha ubukhulu obukhulu buvakala ngcono, uRaschke unezilumkiso ezisekelwe kwibhloko yakho, intloko, kunye noko kufuneka ukwenze ukuze usebenzise i-pimple enkulu.
“Ngezi zikhewu, abanye abantu basebenzisa ne-9/16 okanye i-5/8,” utshilo. “Ekugqibeleni, ungabeka i-stud enkulu, kodwa udonga lwesilinda aluyi kuyixhasa, okanye akukho ndawo ye-gasket yentloko yesilinda, kwaye uya konakalisa ibhloko. intloko ayinamandla ngokwaneleyo okuphatha ii-clamps eziphezulu Imithwalo enzima? Zininzi izinto ekufuneka uzicinge endaweni yokufaka into enamandla. Kwakhona kufuneka ube ne-head washer eneempawu zokwakha ukuze ukwazi ukusingatha oku.
“Kwi-gasket enezitezi ezininzi ethengiswayo namhlanje, kufuneka ube nezibophelelo ezixolelayo kwisithuthi sasemgwaqweni kunakwimoto yomdyarho, kuba ngemoto yomdyarho kunokwenzeka ukuba uyiqhaqhe kwaye uyilungise rhoqo, ngelixa i-streetcar kuya kufuneka iqhutywe ngamakhulu amawaka eekhilomitha. Awunakuyenza i-headrest ibe ncinci, kwaye awukwazi ukuyandisa kwaye uyicinezele.”
UZeigler uphendule kwezi zimvo ngokuthi azifuneki izikhonkwane ezinkulu okanye izinto ezinzima kwiimeko ezininzi.
“Ukuba yi-app ethobekileyo engenanto ingaqhelekanga ngayo, akukho sizathu sokuchitha imali eninzi kangaka,” utshilo uZiegler. “Ukuba umsebenzi wenziwe kakuhle, iseti elungileyo yeebholiti ezineewasher ezilungileyo kunye nokulungiswa okusemgangathweni akuyi kuba yingxaki.”
Njengakwimisebenzi emininzi yenjini, ukwenza umsebenzi ngendlela eyiyo kuphumelela nge-99%. Oku kuyasebenza nasekubotshelelweni kwebholthi yentloko. Sidibene noJustin kwiZeigler Diesel Performance ukuze sibukele iGator Fastener ifaka iseti yeebholthi zentloko ze-12mm kwinjini yevalvu yeCummins 24.
Ngoko nangoko, uJustin wancoma iGator ngokupakisha kwayo kunye nokubonakaliswa kwayo. Iziqwenga zeGator kunye ne-ARP ziza kwibhokisi enobukhulu obufanayo, equka izixhobo ezifunekayo, izibhengezo ezibhalwe uphawu, kunye nemiyalelo yokufakela. Iziqwenga ze-ARP zihlala zipakishwa kwiibhushi zeplastiki ezahlukeneyo kunye neenati kunye neewasher kwiingxowa zeplastiki. Ngee-clasp zeGator, iziqwenga zigcinwa kwibhokisi yeplastiki entle, isiqwenga ngasinye sinesigqubuthelo seplastiki ukukhusela imisonto, kwaye iziqwenga kunye neenati ziza kwiingxowa ezahlukeneyo. Omnye umahluko omkhulu kukuthambisa okubonelelwayo. I-ARP inikezela ngephakheji encinci yegrisi kwaye iGator inikezela ngetyhubhu enkulu yegrisi yokufaka ye-AMSOIL.
Ngaphambi kokufaka naziphi na izikhonkwane nasemva kokufaka ipompo kumngxuma ngamnye, ucoceko lubalulekile ukuze kuthintelwe iingxaki kamva.
“Eyona nto ibalulekileyo kukugxila kucoceko,” utshilo uZiegler. “Xa ukhuphe imingxunya, kufuneka uyivuthele ngomoya uze usule yonke into nge-brake cleaner ukuqinisekisa ukuba yonke into esinayo icocekile kakhulu ngaphambi kokuba sibeke ii-pads phezu kwayo.”
Isixhobo se-Cummins Gator stud siza nee-studs ezingama-26 – ii-studs ezinde ezi-6 ngaphandle kwentloko kunye nee-studs ezimfutshane ezingama-20 ngaphakathi. I-stud nganye ithanjiswe ngegrisi yokufakela ngaphambi kokuba ifakwe entloko nakwibhloko. Njengee-studs ze-ARP2000, ezi ngwenya ze-12mm zifuna ulandelelwano lwe-torque ezintathu ukuze zifikelele kwi-125 ft-lbs. (40, 80 kunye ne-125). Kwelinye icala, ii-studs ze-ARP 625 zifikelela kwi-150 ft-lbs. (50, 100, 150). Imiyalelo yomibini le nkampani ichaza ngokulula indlela yokusifaka i-stud endaweni yayo.
Njengoko bekutshiwo, i-ARP iyile zonke izikhonkwane, ngoko ke kuyacetyiswa ukuba uzifake kuphela xa umthwalo ufikelela kwi-80%, ukuba ufuna zibe ngqongqo ngakumbi ukuze zandiswe, akukho 20% yokuzincamathelisa. Akukho Gator okanye ARP abakuxelelayo ukuba izikhonkwane zabo zingaphinda zisetyenziswe na. UJustin angakuxelela ngokwakhe oko unako.
“Kwiminyaka embalwa eyadlulayo, itrektara yam yayinezikhonkwane ze-ARP ezifanayo zeenjini ezintlanu ezahlukeneyo,” utshilo. “Ndazilinganisa kwaye akukho nto yayinwebeka okanye itshintshileyo, ngoko ke ndizisebenzisa rhoqo kwaye andizange ndibe nangxaki.”
Ukufakelwa kwe-stud kungathatha iiyure ezi-4-6 kuxhomekeke kumsebenzi. Ukuba awunayo indawo yakho yokusebenzela umatshini, into ekuphela kwayo ongenakukwazi ukuyilinganisa kukuthumela intloko ukuze igqitywe.
Lilonke, ii-hairpin azikho kwizibalo eziphezulu, kwaye azizizo izinto ezifunekayo, kodwa usafuna ukuqinisekisa ukuba wenza umsebenzi ngendlela eyiyo, njengoko iziphumo zokuwenza gwenxa zinokuba yintlekele.
“Into ephambili kukukhetha indibaniselwano eqinisekisiweyo,” ucebisa uRaschke. “Abantu baya kwi-intanethi baze bakhethe le turbocharger, le injector, le ntloko kunye nale ring of fire, baze badibanise zonke ezi zinto kwaye azisebenzi. Basebenzisa izimvo zabantu abane okanye abahlanu abahlukeneyo endaweni yokukhetha indibaniselwano ehambelana neemfuno zabo. Xa udala nantoni na, kufuneka uhlale ujonge umfanekiso omkhulu.
"Kufuneka ube nee-washers ezifanelekileyo, umthwalo ofanelekileyo we-clamp, kunye nee-headwashers. Wakuba usebenze kakhulu, ungena kwiiringi zomlilo nezinto ezinjalo."
Ngokutsho kukaZeigler, abantu abaninzi abayiqondi kakuhle into yokuba i-spikes ngokwayo iyasebenza, kodwa bayenza gwenxa xa kufikwa ekulungiseleleni kwayo.
“Ukuqinisekisa ukuba umphezulu wedekhi ucocekile kubalulekile, ingakumbi xa usebenzisa ezi washers zentsimbi ezifakwe ilaminate – umphezulu kufuneka ube semgangathweni,” utshilo uZeigler. “Ufuna ukuba umphezulu uhlale ufana.”
Namhlanje, phantse yonke into ekwinjini inika abathengi iindlela ezahlukeneyo zokukhetha. Nangona kunjalo, izixhobo zenjini zisenokuba yenye yeendawo ezimbalwa apho i-ARP ngokucacileyo iluphawu olukhethwayo ngokusekelwe kumgangatho, amava kunye nemveliso. Oko kulawula kusekude kakhulu, kodwa abadlali abaninzi bangena kwimarike, njengeGator Fasteners, kwaye imiba yakutshanje yecandelo lokubonelela ngeenkonzo inika abanye ithuba.
“Akukho mntu unokuphembelela impumelelo ye-ARP,” uyavuma uZiegler. “Nangona kunjalo, ndicinga ukuba iiGator Fasteners zingaphumelela ukuba aziphumi esandleni kwixabiso. Ixabiso lilungile kwaye umgangatho ulungile ngokuqinisekileyo. Ndicinga ukuba ingaba lukhetho oluhle kakhulu, kungekhona ezinye izinto ze-ARP, kuba ngoku silinde iinyanga ezininzi.”
URaschke uvumile ukuba i-ARP ijongene nemingeni njengoko abavelisi abaninzi bezama ukuhambelana nemfuno. Le nkampani isebenza ukunciphisa amaxesha okulinda kunye nokwandisa imveliso, utshilo.
"Kunzima ukoyisa oko i-ARP ikunika kona, kodwa iiGator Fasteners zibonakala ngathi ziyindlela efanayo."
