Kubuda kwehutsi hwebhuruu kunokonzerwa nekupisa kwemafuta akawandisa mukamuri rinopisa. Zvikonzero zvekukundikana uku ndezvizvi:

1) Pani yemafuta inozadzwa nemafuta. Oiri yakawandisa inorovera pamadziro ecylinder pamwe neiyo high-speed crankshaft uye mukamuri yekupisa. Mhinduro ndeyekumira kwemaminetsi angangoita gumi, wobva watarisa dipstick yemafuta uye wobvisa mafuta akawandisa.

2) Iyo cylinder liner uye piston zvikamu zvakapfekwa zvakanyanya uye clearance yakakura kwazvo. Kana gaka racho rakanyanya kukura, mafuta akawanda achapinda mukamuri yekupisa kuti apise, uye panguva imwe chete, gasi rinopera rejini crankcase richawedzera. Nzira yekurapa ndeyekutsiva zvikamu zvakasakara munguva.

3) Mhete yepiston inorasikirwa nebasa rayo. Kana iyo elasticity yepiston mhete isina kukwana, iyo kabhoni deposits yakanamatira mumhete groove, kana ring port dziri pamutsetse mumwe chete, kana gomba rekudzoka kwemafuta rerin'i remafuta rakavharika, huwandu hwakawanda hwemafuta huchapinda mukati. kamuri yekupisa nekupisa, uye utsi hwebhuruu huchabuda. Mhinduro ndeyekubvisa zvindori zvepiston, kubvisa kabhoni deposits, kugoverazve zviteshi zvemhete (yepamusoro uye yezasi mhete zviteshi zvinokurudzirwa kudzedzereka ne180 °), uye kutsiva zvindori zvepiston kana zvichidikanwa.

4) Kusununguka pakati pevhavha uye duct yakakura kwazvo. Nekuda kwekupfeka uye kubvaruka, mukaha pakati pezviviri izvi wakakurisa. Panguva yekudya, huwandu hukuru hwemafuta mukamuri yerocker arm inoyamwa mukamuri yekupisa yekupisa. Mhinduro ndeyekutsiva valve yakasakara uye conduit.

5) Zvimwe zvinokonzera utsi hwebhuruu. Kana oiri yanyanya kuonda, kudzvanywa kweoiri kwakanyanyisa, uye injini isingashande zvakanaka, zvinokonzeresa kupisa mafuta uye kuburitsa utsi hwebhuruu.
