Shanyira musangano wekuongororwa kwenyanzvi yemamiriro e roller. Nekudaro, zvakakosha kuziva kuti pane mamwe mota mota tinogona kuedza kuzvimiririra kuona mamiriro ecamshafts.

Kupa roller simba rinodiwa, rinoiswa pasi pekupisa uye kurapwa kwemakemikari. Roller regeneration yakawanda zvikuru kune vakwegura kuitira kuderedza mari yebasa. Kugadziriswa kwetrunnion imwe kunotitorera 50-70 PLN, kana tisingatauri nezve injini ine 16-valve musoro - munyaya iyi tichabhadhara 500-700 PLN nokuda kwegomba. Mutengo weshaft yepakutanga yechina-cylinder injini inogona kupetwa kaviri.

Nzira yekudzivirira sei kupfeka pane camshaft?
