Isa ring yepiston yakafuratira mucylinder, sunda ring ring nepiston yekare (kana uchichinja ring kuti igadziriswe zvidiki, isundidzire painoenda neinoenda kwainoenda kwakadzikira), woyera gaka rekuvhura nekukora. gauge.

Kana mukaha wekuvhura uri diki zvakanyanya, shandisa yakanaka faira kufaira zvishoma panovhura. Kuongororwa kazhinji kunofanira kuitwa panguva yekugadzirisa faira kudzivirira kuvhura kubva pakunyanya kukura, uye kuvhura kunofanira kunge kwakadzika. Kana kuvhurwa kwemhete kwakavharwa kuongororwa, hapafanirwe kuve nekutsauka; iyo yakadhindwa yekupedzisira inofanira kunge isina maburrs.

Tarisa kumashure, isa mhete yepiston mugoro remhete woitenderedza, woyera gap negeji yekukora pasina kuburitsa pini. Kana iyo clearance iri diki, isa rin'i yepiston paplate furati yakavharwa nemucheka we emery kana ndiro yegirazi yakavharwa nejecha vharafu uye ukuye mutete.

Tarisa kumashure uye uise mhete yepiston mugororo remhete, mhete yakadzikira pane groove bank, zvikasadaro ring groove inofanira kuchinjirwa panzvimbo yakakodzera.
