Kuti mudziwe mtundu wa nati yoyenera kugwiritsa ntchito, muyenera kuganizira zinthu zinayi zosiyana: mtundu wa mpando, kukula kwa ulusi, kupendekera kwa ulusi ndi mtundu woboola.
1. Mtundu wa Mpando
Kapangidwe ka mpando ndi malo omwe lug nati imakumana ndi pamwamba pa gudumu. Monga tanenera kale, mitundu yodziwika bwino ya mipando ndi yathyathyathya, yozungulira, komanso yozungulira. Makamaka, conical lug nati ya madigiri 60 ndi kapangidwe kodziwika bwino ka lug nati. Conical pati imathandiza kuyika pakati pa gudumu pamene lug nati zamangidwa. Chifukwa chake, mutha kukhala ndi zinthu zolinganizika bwino kuposa momwe mungakhalire ndi Mag kapena Shank pati.
Kumbali inayi, mipando yokhala ndi mawonekedwe a madigiri 45 imagwiritsidwa ntchito kwambiri pamawilo ozungulira. Ndipotu, simuyenera kugwiritsa ntchito ma lug nuts a madigiri 45 pa gudumu la OEM lomwe lili ndi mpando wokhala ndi mawonekedwe a madigiri 60.
2. Kukula kwa Ulusi
Kuti mudziwe ulusi wa mtedza wa lug womwe mukufuna pagalimoto yanu, muyenera kudziwa kukula kwa ulusi. Kuti muchite izi, choyamba yesani kukula kwa ulusi wakunja kwa gudumu la galimoto. N'zovuta kupeza miyeso yolondola pogwiritsa ntchito tepi yoyezera yokha. M'malo mwake, seti ya ma caliper a digito imagwiritsidwa ntchito kudziwa kukula kwa ulusi. Ma diameter odziwika kwambiri a ulusi wa mtedza wa lug pogwiritsa ntchito kukula kwa SAE ndi mainchesi 7/16, 1/2, 9/16, ndi 5/8.
3. Kufotokozera kwa Ulusi
Kuti mudziwe kutalika kwa ulusi, muyenera kuwerengera kuchuluka kwa ulusi womwe uli m'mbali mwa ulusi wa inchi imodzi. Gwiritsani ntchito tepi yoyezera kudula inchi imodzi ya mzere ndikuwerengera kuchuluka kwa ulusi pamanja. Ma pitches odziwika kwambiri a mtedza wa SAE-size lug ndi 7/16 "-20, 1/2" -20, 9/16 "-18, 5/8" -18, ndi 5/8 "-11".
4. Mtundu Wothira
Kenako, tifunika kudziwa mtundu wa wrench. Mtedza wa hexagon ndi womwe umapezeka kwambiri, ndipo manja ndi ma wrench onse amatha kuyikidwa kapena kuchotsedwa mosavuta. Ngakhale izi zimapangitsa kuti makaniko anu am'deralo kapena ogulitsa matayala azichotsa mawilo anu mosavuta, zimapangitsa kuti akhale pachiwopsezo cha kuba. Ngati mukuda nkhawa ndi kuba, tikukulimbikitsani kuganizira zogula seti ya ma wrench.

Ma spline drive ndi hex key nuts onse amafunika makiyi kapena zida zapadera kuti aziyike ndikuchotsa. Spline drive lug nuts amagwiritsidwa ntchito kuti agwirizane ndi kalembedwe ka gudumu linalake kapena kusintha mawonekedwe onse. Kapenanso, pazifukwa zachitetezo, mutha kugwiritsa ntchito spline drive lug nut pa gudumu lililonse - lomwe nthawi zambiri limatchedwa wheel lock.

Komabe, mtedza wa hexagon key umawoneka bwino ndipo nthawi zambiri umagwiritsidwa ntchito pa mawilo okhala ndi mabowo ang'onoang'ono ozungulira kuti mtedzawo ugwirizane bwino. Ubwino waukulu wa mitundu iyi ya mtedza wa lug ndi wakuti suwononga pamwamba pake chifukwa sukhudza malo aliwonse akunja akayikidwa kapena kuchotsedwa.
