(1) Iyo giya yekubatanidza clearance yakakura kwazvo kana idiki.
(2) Nzvimbo yepakati pakati pe crankshaft main bearing gomba uye camshaft ine gomba inoshanduka panguva yekushandiswa kana kugadzirisa, ichiva hombe kana diki; iyo crankshaft uye camshaft yepakati mitsetse haina kufanana, zvichikonzera kushata kwegiya meshing.
(3) Kusaruramisa kugadziridzwa kwegiya zino mbiri, deformation panguva yekupisa kurapwa kana kunyanyisa kupfeka pamusoro pemazino;
(4) Gear rotation--Mukaha uripakati pemagapu anotsenga mudenderedzwa hauna yunifomu kana kuti undercut inoitika;
(5) Pane mavanga, delamination kana meno akatyoka pamusoro zino pamusoro;
(6) Giya rakasununguka kana kunze kwe crankshaft kana camshaft;
(7) Gear end face denderedzwa runout kana radial runout yakakura zvakanyanya;
(8) Iyo axial clearance ye crankshaft kana camshaft yakakura kwazvo;
(9) Magiya haana kutsiviwa ari maviri maviri.
(10) Mushure mekutsiva crankshaft uye camshaft makwenzi, giya meshing chinzvimbo chinoshandurwa.
(11) Iyo camshaft yenguva yegiya yekugadzirisa nati yakasununguka.
(12) Mazino eiyo camshaft yenguva giya akatyoka, kana giya rakatyoka munzira yeradial.
