Akuyona imfihlo ukuthi ezicini eziphakeme zokuvutha, kubaluleke kakhulu ukuthi ikhanda le-cylinder liphumule kahle ngokumelene nobuso be-cylinder block. Ngakho-ke kubaluleke kakhulu ukukhetha uhlobo lwezingubo zasekhanda ozethembayo ukuze wenze umsebenzi wenziwe.
Kungakhathaliseki ukuthi uneloli lomsebenzi elisebenza usuku lonke, iloli elakhelwe umsebenzi oguquguqukayo, noma okuthile phakathi, akungabazeki ukuthi wonke amaloli azozuza kusethi entsha yamabhawodi ekhanda lamasilinda.
Uma kuziwa ekuthengeni izixhumi zenjini njengama-stud, sekuyisikhathi eside ziphezulu ohlwini - i-ARP. I-ARP isineminyaka engaphezu kwengu-50 ikhona futhi, ngokwekhredithi yayo, iyaqhubeka nokulwela ukukhiqiza izixhumi zokusebenza eziphezulu zezicelo ezifunayo. Kodwa-ke, ukuncintisana kule ndawo kuyanda muva nje futhi enye yezinkampani ezibanga isabelo semakethe yiGator Fasteners, i-KT Performance brand yaseGroveland, eFlorida.
Akuyona imfihlo ukuthi ezicini eziphakeme zokuvutha, kubaluleke kakhulu ukuthi ikhanda le-cylinder liphumule kahle ngokumelene nobuso be-cylinder block. Ngakho-ke kubaluleke kakhulu ukukhetha uhlobo lwezingubo zasekhanda ozethembayo ukuze wenze umsebenzi wenziwe. Sisanda kukhuluma ne-ARP mayelana nemikhiqizo yabo ye-head stud futhi saphinde sakhuluma ne-Zeigler Diesel Performance e-Canton, e-Ohio mayelana nezibophelelo ze-Gator zakamuva kuma-specs nobuchwepheshe benkampani ngayinye, kanye nokunye okufanayo. kanye nokwehluka okuhambisana nazo. esixukwini sikadizili.
Imvamisa, i-fastener yefekthri namuhla iyisibopheli samandla esivuno esilahlwayo. Lokhu kusho ukuthi ngokuhamba kwesikhathi kunethuba elikhulu kakhulu lokuthi uzophakamisa ikhanda le-cylinder off the block futhi ulimaze i-cylinder head gasket. Amabhawodi e-Aftermarket asuka ku-ARP noma e-Gator Fasteners awanwebi njengamabhawodi asefekthri ngoba awanawo amandla okukhiqiza itorque.
“Mayelana nokusebenza kukadizili, sijwayele ukudlula imishini yasefekthri ngamaphesenti angama-20,” kusho uChris Raschke we-ARP. "Yilokho obekugxilwe kukho kanye nomgomo. Besifuna nokuthile esingasebenziseka kabusha. Abantu abaningi esikhulume nabo basebenzisa i-ARP2000 nezinzipho ezingu-625."
I-ARP inikezela ngamakhithi ebhawodi ekhanda ezinhlobonhlobo zezinjini zegesi nezezidizili, futhi izixhumi ze-Gator nazo zilingana nezinkundla ezinkulu zenjini kadizili. Kodwa-ke, i-Gator ibonakala ingekho ohlangothini lwegesi emakethe, kodwa iza nenketho ye-bolt yekhanda le-LS.
Ezinjinini zikadizili, amabhawodi e-Gator akhelwe izinjini ze-Duramax ezingu-2001 kuze kufike futhi afake injini ebuyekeziwe engu-2020 L5P. Izinjini ze-Powerstroke ne-Cummins zisuka ku-Rams ngo-1989 ziye ku-Powerstroke ngo-1994 kuze kube kulo nyaka.
“Ama-Gator mounts abukeka ehle kakhulu uma eqhathaniswa nalokhu engikubonile,” kusho u-Justin Zeigler weZeigler Diesel Performance. "Ngibone ezinye izigxivizo ezingabazekayo ezivela kwabanye abakhiqizi. I-ARP ibizisebenzisa isikhathi eside kunanoma ubani omunye. Kodwa-ke, ngicabanga ukuthi izinsimbi ze-Gator ziyinketho enhle nokukhetha okuhle. Ngithanda ikhwalithi, intengo nokutholakala. 'saw."
Ngamandla aqinile angaphezu kuka-220,000 psi, izibophelelo ze-Gator ngeke zinwebe njengamabhawodi asefekthri. Akhiwa ngemicu egoqiwe ngemva kokwelashwa kokushisa ukuze aqinise amandla okukhathala. Ayinandawo emaphakathi yokugxila futhi ikhithi ngayinye ihlanganisa insimbi ye-chrome ephathwa ngokushisa, amantongomane angu-12 aphansi kanye namawasha ane-black oxide enamathelayo ukuze iqine.
Nakuba i-Gator njengomkhiqizo omusha inganikeza ngokwemvelo umkhiqizo we-premium, isantula umehluko omkhulu nomkhulu we-ARP - ulwazi.
“Sisebenzisa i-torque tensioner ukuhlola izinsimbi zasefekthri kanye nendlela yokufaka efekthri ukuze sihlole imithwalo yokubopha oyithola kuma-fasteners asefekthri,” kuchaza u-Raschke. "Yilokho esikwakhe kusukela lapho. Futhi sinesimo sokuhlola esishisayo, okuyisithando somlilo esinegumbi lokuhlola ngaphakathi, futhi ungakwazi ukushisisa yonke into kufikela kuzinga lokushisa lokusebenza kwenjini ukuze ubone ukuthi liwathinta kanjani ama-fasteners ezingeni lokushisa elisebenzayo. Uma sidala ama-fastener kits anoma yiluphi uhlelo lokusebenza, kufanele sicabangele lezi zici. Sinamathuluzi amaningi ebhokisini lethu lamathuluzi ukwenza esikudingayo."
Amafasteners esikhathini esidlule asebenzise impahla engu-8740 ku-180,000-200,000 psi, ehlale ingaphezu kokwanele ukufaka indawo yemishini yefekthri. Namuhla, amabhrendi afana ne-ARP anikeza amakhasimende ukukhetha kwe-ARP2000, i-Inconel noma i-Custom Age 625 PLUS enamandla amakhulu okunyakazisa.
“Ngezinto ezingu-8740, ungakwazi kuphela ukuphatha cishe u-200,000 psi, okungama-38-42 esikalini se-Rockwell, futhi yilapho ubumnandi buqala khona,” kusho u-Raschke. "Uma uzama ukuliphakamisa, uzokhathala izikhonkwane zekhanda. Kufanele ukhethe izinto ezisebenza lapho okufanele ziziphathe khona."
I-ARP 2000 yenze kahle kakhulu ku-220,000 psi futhi, ngokusho kuka-Raschke, yayisenezindawo ezinhle zokukhathala kanye ne-ductility enhle ekulayishweni okuphezulu kwama-clamp. Ukusuka lapho, i-ARP inikezela ngezinto zayo zangokwezifiso zeminyaka.
“Enye yezinto ezinhle ngeCustom Age ukuthi iyinsimbi engenasici engeke igqwale,” kusho uRaschke. “Inamandla aphezulu okudonsa (260,000+ psi) ukuze ukwazi ukuyinyakazisa futhi uhlale ujabule.Iyinsimbi engagqwali futhi, inkinga ngodizili banokushisa okukhulu, umswakama, i-exhaust – yilokho nje “Akufani nemishini yensimbi evamile. I-Corrosion ikhipha i-hydrogen, futhi i-hydrogen embrittlement ingalimaza izinsimbi. Uma ushisisa ngokweqile izikhonkwane ukuze uzenze ziqine, uzoba nokugqwala okubangelwa ukugqwala. Amathuba ezinkinga ze-hydrogen embrittlement aphindeka kabili.”
Yiqiniso, akuyona nje impahla enomthelela ku-spike evumelana kangcono nezidingo zakho, kodwa futhi nobukhulu bayo. Ngokuvamile, amabhawodi ekhanda angu-12mm angasetshenziswa ezinhlelweni eziningi ze-Cummins. Kodwa-ke, abanye abantu abenza kahle kakhulu bangasebenzisa izigxivizo ezingu-14mm, izigxivizo ezingu-9/16, noma ngisho nezigxivizo ezingu-5/8.
"Ezimweni eziningi, yonke imboni yakho i-Cummins izoba yizikhonkwane ezingu-12mm," kusho u-Ziegler. "Emhlabeni womjaho, besihlale sisebenzisa u-14mm noma u-9/16 ukuthola itorque ephezulu. Amabhawodi ekhanda emotweni yami yomjaho ane-torque efinyelela ku-250 ft.lbs. Lawo ma-12mm angu-125 ft.lbs. Umehluko omkhulu ekubambeni, kodwa futhi kuwuhlelo oluhluke kakhulu."
U-Raschke uthe abantu abaningi e-Cummins baqale ukumba izikhonkwane ezinkulu ngenxa nje yokuthi babengenazo izinto eziqinile ezanele esikhathini esidlule. Manje, sibonga i-ARP, sebekwenzile.
“Yize abantu besafuna ukusebenza ngama-blocks, sibahlinzeka ngezinto ezisezingeni eliphezulu,” kusho yena. "Isixazululo sethu ngokuvamile siwukwenza izibophelelo zekhwalithi ephezulu ukuze zisetshenziswe efekthri. Uma ufuna ukushintsha okuthile, umnyango wethu wochwepheshe uyahlanya. Sisebenze ezimotweni eziningi ezihlukene zikadizili. Abakhi benza lokhu, isibonelo, u-Shade, u-Heisley, u-Wagler nabanye".
Nakuba ngezinye izikhathi usayizi omkhulu uzwakala kangcono, u-Raschke unezixwayiso ezisekelwe kubhulokhi yakho, ikhanda, nalokho okudingeka ukwenze ukuze usebenzise induna enkulu.
“Ngalezi zikhala, abanye abantu baze basebenzise u-9/16 noma u-5/8,” kusho yena. "Ekugcineni, ungafaka i-stud enkulu kakhulu, kodwa udonga lwesilinda ngeke luyisekele, noma ayikho indawo ye-cylinder head gasket, futhi uzobhubhisa i-block. ikhanda alinamandla okwanele ukuphatha ama-clamps aphezulu Imithwalo esindayo? Kukhona izinto eziningi ongazicabanga esikhundleni sokubeka into enamandla. Udinga futhi ukuba ne-structure washer yekhanda ukuze ube ne-structure washer.
"Ukuze uthole i-multi-layer gasket edayiswayo namuhla, udinga ukuba nezinsimbi ezithethelela kakhulu emotweni yomgwaqo kunasemotweni yomjaho, ngoba ngemoto yomjaho maningi amathuba okuthi uyihlukanise futhi uyisevise kaningi, kanti inqola yomgwaqo izodinga ukushayelwa amakhulu ezinkulungwane zamakhilomitha.
U-Zeigler uphendule lawa mazwana ngokuthi izikopelo ezinkulu noma izinto ezisindayo azidingeki ezimweni eziningi.
“Uma kuwuhlelo lokusebenza oluthobekile olungenayo into engenangqondo ngalo, asikho isizathu sokusebenzisa imali engaka,” kusho uZiegler. “Uma umsebenzi wenziwe kahle, isethi enhle yamabhawodi anamawasha amahle kanye nokulungiswa kwekhwalithi ngeke kube yinkinga.”
Njengomsebenzi omningi wezinjini, ukwenza umsebenzi wenziwe kahle kuyimpumelelo engama-99%. Okufanayo kusebenza ekuqinisweni kwe-bolt yekhanda. Sihlangane noJustin e-Zeigler Diesel Performance ukuze sibuke i-Gator Fastener ifaka isethi yamabhawodi ekhanda angu-12mm enjini ye-Cummins 24 valve.
Ngokushesha, u-Justin wancoma i-Gator ngokupakisha nokwethulwa kwayo. Izikhonkwane ze-Gator ne-ARP ziza ngebhokisi likasayizi ofanayo, elihlanganisa izingxenyekazi zekhompuyutha ezidingekayo, amadecal anegama, nemiyalelo yokufaka. Izikhonkwane ze-ARP zivame ukupakishwa ezihlahleni zepulasitiki ngazinye namantongomane namawasha ezikhwameni zepulasitiki. Ngama-clasps e-Gator, ama-studs afakwe ebhokisini lepulasitiki elihle, i-stud ngayinye inekepisi lepulasitiki lokuvikela izintambo, futhi ama-washer namantongomane afika ezikhwameni ngazinye. Omunye umehluko omkhulu yi-lubrication enikeziwe. I-ARP ihlinzeka ngephakheji elincane lamafutha futhi i-Gator ihlinzeka ngeshubhu elikhulu lamafutha afaka i-AMSOIL.
Ngaphambi kokufaka noma yiziphi izikhonkwane nangemuva kokufaka impompi emgodini ngamunye, ukuhlanzeka kubalulekile ukugwema izinkinga kamuva.
"Into ebaluleke kakhulu ukugxila ekuhlanzekeni," kusho uZiegler. “Uma usubhobozile izimbobo, kufanele uzifuthe ngomoya bese wesula yonke into nge-brake cleaner ukuze uqiniseke ukuthi yonke into esinayo ihlanzeke kakhulu ngaphambi kokuthi sibeke amaphedi phezulu.”
Ikhithi ye-Cummins Gator stud iza nama-stud angama-26 - izikhonkwane ezinde eziyisi-6 ngaphandle kwekhanda kanye nezikhonkwane ezimfishane ezingu-20 ngaphakathi. I-stud ngayinye igcotshwa ngamafutha afakwayo ngaphambi kokufakwa ekhanda kanye nebhulokhi. Ngokufanayo nama-ARP2000 studs, lawa ma-alligator angu-12mm adinga ama-torque amathathu alandelanayo ukuze afinyelele ku-125 ft-lbs. (40, 80 kanye ne-125). Ngakolunye uhlangothi, izikopelo ze-ARP 625 zikhuphukela ku-150 ft-lbs. (50, 100, 150). Imiyalo yomibili le mikhiqizo ichaza kalula ukuthi isikulufi sifakwa kanjani endaweni.
Njengoba kushiwo, i-ARP iklame zonke izikhwebu, ngakho-ke kunconywa ukuzifaka kuphela ngomthwalo we-80%, uma ufuna ukuthi ziqine ukuze zinwetshwe, i-cushioning engu-20% iyatholakala. I-Gator noma i-ARP ayikutsheli uma izitudi zabo zingasetshenziswa kabusha. UJustin angakutshela mathupha lokho ongakwenza.
“Eminyakeni embalwa edlule, ugandaganda wami wawunezigxivizo ze-ARP ezifanayo zezinjini ezinhlanu ezihlukene,” esho. “Ngazilinganisa futhi akukho okweluliwe noma okushintshile, ngakho ngizisebenzisa ngaso sonke isikhathi futhi angikaze ngibe nenkinga.”
Ukufakwa kwe-stud kungathatha amahora angu-4-6 kuye ngomsebenzi. Uma ungenaso esakho isitolo somshini, okuwukuphela kwento ongakwazi ukuyilinganisa nayo ukuthumela ikhanda ukuze liqedelwe.
Sekukonke, izikhonkwane zezinwele azizona izibalo eziphakeme, futhi azizimiseli, kodwa usafuna ukwenza isiqiniseko sokuthi wenza umsebenzi ngendlela efanele, njengoba imiphumela yokuwenza ngendlela engalungile ingaba yinhlekelele.
"Into eyinhloko ukukhetha inhlanganisela efakazelwe," u-Raschke weluleka. “Abantu bangena kwi-internet bakhethe le turbocharger, le injector, leli khanda nalendandatho yomlilo, bese behlanganisa zonke lezi zinto ndawonye kodwa namanje akusasebenzi.Basebenzisa imibono yabantu abane noma abahlanu abahlukene esikhundleni sokukhetha inhlanganisela ehambisana nezidingo zabo.Lapho udala noma yini, udinga ukubheka isithombe esikhulu ngaso sonke isikhathi.
"Kufanele ube namawasha alungile, isigxivizo esifanele, namawasha amakhanda. Uma usufinyelele ukusebenza okweqile, bese ungena kumasongo omlilo nokunye okunjalo."
NgokukaZeigler, akubona abantu abaningi abakuthola kungalungile uma kuziwa kuma-spikes ngokwabo, kodwa kunalokho ukulungiselela kwabo.
"Ukuqinisekisa indawo ehlanzekile yedekhi kubalulekile, ikakhulukazi uma usebenzisa lawa mawasha ensimbi ane-laminated - ukuphela kwendawo kufanele kube okulungile," kusho uZeigler. "Ufuna ukuthi isiphetho esingaphezulu sihlale sifana."
Namuhla, cishe yonke ingxenye yenjini inikeza abathengi izinketho ezihlukahlukene. Kodwa-ke, i-hardware yenjini ingaba enye yezindawo ezimbalwa lapho i-ARP ngokusobala iwuphawu olukhethwayo ngokusekelwe kukhwalithi, ulwazi nomkhiqizo. Lokho kubusa kusekude nokuqinisekile, kodwa abadlali abaningi bangena emakethe, njenge-Gator Fasteners, futhi izindaba zakamuva ze-supply chain zinika abanye umkhawulo.
“Akekho ongathonya impumelelo ye-ARP,” kuvuma uZiegler. "Kodwa-ke, ngicabanga ukuthi i-Gator Fasteners ingaba yimpumelelo uma ingaphumi esandleni ngentengo. Intengo ilungile futhi ikhwalithi isezingeni elifanele. Ngicabanga ukuthi kungaba inketho enhle ngempela, hhayi ezinye izinto ze-ARP, ngoba manje silinde izinyanga ezimbalwa."
U-Raschke uvumile ukuthi i-ARP ibhekene nezinselelo njengoba abakhiqizi abaningi bezabalaza ukuhambisana nesidingo. Uthe le nkampani isebenzela ukunciphisa isikhathi sokulinda futhi inyuse izinga lokusebenza.
“Kunzima ukwehlula lokho i-ARP ekunika kona, kodwa ama-Gator Fasteners abukeka njengenketho elinganayo.”
