(1) Mugihe cyo gusana, menya neza inteko

Mugihe cyo guteranya crankshaft ya moteri ya mazutu, buri ntambwe igomba kuba yuzuye. Mbere yo gushiraho igikonjo, sukura igikarabiro hanyuma usukure inzira ya peteroli hamwe numwuka mwinshi. Imashini zimwe zifite umwobo wo kuruhande kandi zifunze imigozi. Umwanda watandukanijwe namavuta kubera imbaraga za centrifugal uzegeranya hano. Kuraho imigozi hanyuma uyisukure neza.

Mugihe cyo guteranya crankshaft, birakenewe guhitamo ibyuma byujuje ubuziranenge kandi bikaba kurwego rumwe na crankshaft kugirango umenye neza ko aho uhurira nikinyamakuru kirenga 75%. Ingingo zo guhuza zigomba gutatana kandi zihamye (mugenzura ibyerekeranye). Gukomera bigomba kuba bikwiye. Nyuma yo gukomera kuri bolts ukurikije itara ryerekanwe, ibimera bigomba kuzunguruka mubwisanzure. Gufata cyane bizongera kwambara crankshaft hamwe no gutwara, kandi kurekura cyane bizatera igihombo cyamavuta kandi byongere no kwambara.

Ihinduranya rya axial ya crankshaft ihindurwa na padi. Mugihe cyo gusana, niba icyuho cya axial ari kinini cyane, igikonjo kigomba gusimburwa kugirango harebwe ko icyuho kiri murwego runaka. Bitabaye ibyo, igikonjo kizagenda gisubira inyuma iyo ikinyabiziga kizamutse kikamanuka, bigatera kwambara bidasanzwe inkoni ihuza hamwe na crankshaft.


(2) Menya neza ubwiza nisuku byamavuta yo gusiga

Koresha amavuta yo gusiga urwego rwiza. Amavuta ya moteri akwiye agomba guhitamo ukurikije umutwaro wa moteri ya mazutu. Amavuta yo mu rwego urwo arirwo rwose azahinduka mugihe cyo gukoresha. Nyuma ya mileage runaka, imikorere izangirika, bitera ibibazo bitandukanye kuri moteri ya mazutu. Mugihe cyo gukora moteri ya mazutu, gaze yumuvuduko mwinshi gaze, umuriro, aside, sulfure na azote mu cyumba cyo gutwika bizinjira mu gikarito binyuze mu cyuho kiri hagati yimpeta ya piston nurukuta rwa silinderi, hanyuma uvange nifu yicyuma yambarwa hanze n'ibice kugirango ube umwanda. Iyo umubare ari muto, izahagarikwa mu mavuta, kandi iyo umubare ari munini, izagwa mu mavuta, izahagarika akayunguruzo n’amavuta. Niba akayunguruzo kahagaritswe kandi amavuta ntashobora kunyura muyunguruzo, azacamo ibice byayunguruzo cyangwa afungure valve yumutekano, hanyuma anyure kuri valve ya bypass, azane umwanda mugice cyamavuta, yongere umwanda wamavuta kandi yongere imyenda yambarwa. Kubwibyo, amavuta agomba guhinduka buri gihe kandi igikarito kigomba gusukurwa kugirango imbere ya moteri ya mazutu isukure kugirango igikonjo gikore neza.


(3) Kugenzura cyane ubushyuhe bwakazi bwa moteri ya mazutu

Ubushyuhe bufitanye isano cyane no gusiga amavuta. Mugihe ubushyuhe bwiyongereye, ubukonje bwamavuta buba hasi, kandi firime yamavuta ntabwo yoroshye kuyikora. Impamvu yubushyuhe bwo hejuru ni ubushyuhe buke bwo gukwirakwiza sisitemu yo gukonjesha, ingese no gupima imirasire y’amazi nibibazo bisanzwe. Ingese nubunini bizagabanya umuvuduko wa coolant muri sisitemu yo gukonjesha. Igipimo cyinshi kizagabanya umuvuduko wamazi, kugabanya ingaruka zo gukwirakwiza ubushyuhe, kandi bitera moteri ya mazutu gushyuha; icyarimwe, kugabanya igice cyumuyoboro wamazi bizongera umuvuduko wamazi, bitera amazi kumeneka cyangwa amazi yuzura Amazi Yuzuye, amazi akonje adahagije, byoroshye gufungura inkono; na okiside yamazi akonje nayo azakora ibintu bya acide, bizonona ibice byicyuma cyumuriro wamazi kandi byangiza. Kubwibyo, imirasire yamazi igomba guhanagurwa buri gihe kugirango ikureho ingese nubunini muri yo kugirango imikorere isanzwe ya crankshaft. Ubushyuhe bukabije bwa moteri ya mazutu crankshaft nabwo bujyanye nigihe cyo gutera lisansi, bityo igihe cyo gutera lisansi kigomba guhinduka neza.
