1. Zimapezeka kuti m'magawo ena a makina oyezera mchenga wa ng'oma, choyezera chozungulira chikakhudza mkati mwa makina oyezera mchenga, momwe choyezera chozungulira chimagwirira ntchito komanso chozungulira chimasinthanso, zomwe zimakhudza kukhazikika kwa makina oyezera mchenga. Kukanda ndi kupukuta choyezera chozungulira kuti choyezera mchenga ndi choyezera chozungulira zigwirizane ndi mphete yakunja.
2. Ngati kuchuluka kwa mafuta mu makina oyeretsera mchenga wa ng'oma sikukwanira, yang'anani ngati chivundikiro chapansi cha chimango, ma bearing ndi ma flange, malo olumikizira mapaipi amafuta a chipangizo choteteza fumbi akutuluka, komanso ngati chitoliro cholowera mafuta ndi fyuluta yamafuta zatsekedwa. Kodi mulingo wa mafuta mu thanki yamafuta ndi woyenera, ndipo kuchuluka kwa mafuta mu pampu yamafuta ndi kwabwinobwino? Vuto likapezeka, liyenera kuthetsedwa mwachangu momwe zingathere.
3. Mpata pakati pa shaft yayikulu ya makina owunikira mchenga wa ng'oma ndi bushing yopapatiza iyenera kukwaniritsa miyezo yaukadaulo. Ngati mpatawo ndi wochepa kwambiri, njira yowonjezera gasket pakati pa chimango chozungulira ndi pamwamba pa chimango cha thupi ingagwiritsidwe ntchito kukweza makina owunikira mchenga. Pofuna kusintha mpata pakati pa shaft yayikulu ndi bush yozungulira, kuti ikwaniritse zofunikira zaukadaulo.
