(2) Kuyang'ana kupindika kwa crankshaft (pogwiritsa ntchito pamwamba pa chopukusira kapena lathe, ngati zinthu sizikukwanira, nsanja ndi chitsulo chooneka ngati V chingagwiritsidwenso ntchito). Gwiritsani ntchito pamwamba pa chopukusira kapena lathe kuti mugwirizane ndi mabowo apakati pa malekezero onse a crankshaft (gwiritsani ntchito chuck kuti mutseke malekezero onse a crankshaft) kuti muyike crankshaft. Onani kulondola kwa dzenje lapakati. Gwiritsani ntchito micrometer kuti muwone kusiyana kwa kugwedezeka kwa khosi pakati pa adaputala ya flywheel ndi giya yanthawi (osapitirira 0.5mm pa adaputala ya flywheel, komanso osapitirira 0.6mm pa nyuzipepala ya zida zanthawi). Pamene malire omwe ali pamwambawa adutsa, dzenje lapakati liyenera kudulidwa. Yang'anani kusiyana kwa kugwedezeka pakati pa magazini apakatikati, ikani micrometer pamwamba pa makina opera, pangani singano kukhudza magazini yaikulu yapakati, ndikukankhira crankshaft kuti ikhale yozungulira. Chiwerengero chochuluka cha pointer swings kuchotsera theka laocheperako ndi kupindika (Dziwani kuti ngati pali ellipse pamagazini, iyenera kuchotsedwa), koma sichingadutse muyezo womwe watchulidwa.
(3) Kuyang'ana kuwonongeka kwamakina kwa gawo lililonse lolumikizana. Pakuvala kwa dzenje lakumbuyo kumbuyo kwa shaft, gwiritsani ntchito chizindikiro chamkati kuti muwone ngati chilolezo chapakati chapakati ndi m'mimba mwake chakunja chimaposa malire. Ngati phewa la shaft lavala, yang'anani chilolezo cha axial komanso ngati m'lifupi mwake mapewa amadutsa malire. Pamavalidwe a keyway, chizindikiro chamkati chamkati chingagwiritsidwe ntchito kuyang'ana m'lifupi mwa njira yovulazidwa kwambiri. Flywheel fixing screw mabowo atha, yang'anani kukwanira ndi zomangira zatsopano. Kuphulika kwa ulusi wotsutsana ndi mafuta kungayesedwe ndi template yapadera kapena kuzama kwa phokoso la vernier caliper ndipo kuya sikuyenera kukhala kotsika kusiyana ndi muyezo wotchulidwa. Yang'anani m'mabuku kuti muwone ngati pali mikwingwirima ndi ming'alu.
(4) Kuyang'ana ming'alu ya crankshaft. Ming'alu pamwamba pa magazini, pambuyo popukuta magazini ndikuwonetsetsa mosamala ndi galasi lokulitsa, ming'aluyo idzapezeka bwino.
