Poyerekeza ndi kugwiritsa ntchito mankhwala othandizirana, kusankha kwa zimbalangondo kumakhala ndi zotsatirazi:

Mtengo wothandiza: Kugwiritsa ntchito bush kumatenga chuma chochulukirapo kuposa kuvala. Kubala bush bush kumapangidwa ndi zinthu zochepa zotsika mtengo, pomwe zophatikiza zimafuna kapangidwe kazinthu zovuta komanso njira zopangira, pogwiritsa ntchito zida zambiri zodula. Pakupanga kwakukulu, kusankhidwa kumatha kuchepetsa mtengo wopanga ndikuwongolera phindu lonse lachuma.
Kuthetsa kukana: Kuyatsa bush kumapangidwa ndi zinthu monga mkuwa ndi aluminiyamu aloy, omwe ali ndi vuto lalikulu. Pamene crankshaft imazungulira kuthamanga kwambiri, imakhudzidwa ndi mkangano ndi kukakamizidwa ndi kuvala ziweto zonyamula bwino kumatha kuchepetsa kuvala ndi kuwonongeka ndikuwonjezera moyo wa crankshaft.
Kutentha kwa kutentha: injini imatulutsa kutentha kwambiri pogwira ntchito, ndipo kunyamula zipolopolo kumakhala ndi kutentha kwa kutentha, komwe kumatha kugawana kutentha kwa crankshaft ku stankcaf to crankcaft ndi dongosolo lozizira. Izi zimathandiza kuti corenkshaft zizitentha pamayendedwe ogwiritsira ntchito mankhwala, kuchepetsa kutentha ndi kuwonongeka komwe kumachitika chifukwa cha kutentha.
Kudzilimbitsa nokha: Chipolopolo chonyamula nthawi zambiri chimaperekedwa ndi poyambira mafuta ndi dzenje lamafuta chopatsa mafuta opangira mafuta pamkangano. Mapangidwe onunkhira awa amapanga mafilimu omwe amachepetsa mikangano ndikuvala kwinaku akumachiritsa. Mosiyana ndi zimenezo zimafunikira njira zowonjezera zopangira mafuta ndi zida zopangira mafuta, kuwonjezera zovuta ndi mtengo.
Kukonza mosavuta: Kubala kumakhala kosavuta kuyendera, m'malo mokhala ndi chidwi kuposa kubereka. Pamene crankshaft imavala zovuta kapena kukhala ndi mavuto, kokha chitsamba chokhacho chiyenera kusinthidwa, osatinso zomwe zikuyenera kukwaniritsa. Izi zimasunga nthawi komanso ndalama ndikuchepetsa nthawi yopuma pakukonzanso.
