Don tantance madaidaicin goro don aikace-aikacenku na musamman, kuna buƙatar la'akari da abubuwa huɗu daban-daban: nau'in wurin zama, girman zaren, farar zaren da nau'in wrenching.
1.Nau'in Wurin zama
Siffar wurin zama ita ce yankin da goro a zahiri ke hulɗa da saman ƙafafun. Kamar yadda aka ambata a baya, nau'ikan wurin zama na yau da kullun sune lebur, mai siffar zobe, da kuma conical. Musamman ma, ƙwaya mai madaidaicin digiri 60 shine ƙirar ƙwaya ta gama gari. Wurin zama na juzu'i yana taimakawa tsakiyar dabaran lokacin da aka ƙulla ƙwayayen lugga. Sakamakon haka, za ku iya ƙarasa da ma'auni masu ma'auni fiye da yadda za ku yi da wurin zama na Mag ko Shank.
A gefe guda kuma, ana amfani da kujerun conical na digiri 45 don ƙafafun zagaye zagaye. A zahiri, bai kamata ku taɓa amfani da ƙwaya masu digiri 45 akan motar OEM tare da wurin zama na 60 digiri.
2. Girman Zaren
Don gano abin da zaren nut ɗin da kuke buƙata don abin hawa, kuna buƙatar ƙayyade girman zaren. Don wannan, da farko auna diamita na waje na zaren ingarma ta dabaran abin hawa. Yana da wahala a sami ingantattun ma'auni ta amfani da ma'aunin tef kawai. Madadin haka, ana amfani da saitin calipers na dijital don tantance girman zaren. Matsakaicin diamita na zaren na yau da kullun don ƙwayoyin lugga ta amfani da girman SAE sune 7/16, 1/2, 9/16, da 5/8 inci.
3.Maganin Zare
Don ƙayyade farar, kuna buƙatar ƙididdige adadin zaren tare da ɓangaren inci ɗaya na inci. Yi amfani da ma'aunin tef don yanke inci ɗaya na layi kuma da hannu kirga adadin zaren. Filayen filaye na yau da kullun don ƙwayoyin lugga masu girman SAE sune 7/16 "-20, 1/2" -20, 9/16 "-18, 5/8" -18, da 5/8 "-11
4.Wrenching Nau'in
Na gaba, muna buƙatar ƙayyade nau'in maƙarƙashiya. Kwayoyin lugga na hexagon sun fi kowa, kuma duka hannayen riga da wrenches ana iya shigar da su cikin sauƙi ko cire su. Duk da yake wannan yana sauƙaƙa don makanikin gida ko a shagon taya don cire ƙafafunku, yana sa su zama masu rauni ga sata. Idan kun damu da sata, muna ba da shawarar yin la'akari da siyan saitin makullin ƙafa.

Dukansu spline drives da hex key kwayoyi suna buƙatar maɓalli ko kayan aiki na musamman don shigarwa da cire su. Ana amfani da ƙwayayen ƙwanƙwasa na ƙwanƙwasa don dacewa da takamaiman salon dabara ko don canza kamanni gabaɗaya. A madadin, don dalilai na tsaro, zaku iya amfani da spline drive lug nut don kowace dabaran - wanda aka fi sani da makullin dabaran.

Koyaya, maɓalli na hexagon suna ba da kamanni mai santsi kuma ana amfani da su akan ƙafafu tare da ƙananan ramukan ƙirƙira don kwaya ta dace daidai. Babban fa'idar ire-iren wadannan nau'ikan goro shi ne cewa ba sa yin wani lahani ga saman saboda ba sa haduwa da wani waje idan an sanya shi ko cire su.
