Ruoko rwemuchina werocker mumotokari chaizvoizvo isimbi ine maoko maviri inoshandura simba kubva patsvimbo yekusunda uye inoshanda pamugumo wetsvimbo yevharuvhu kuti ivhure vharuvhu. Chiyero chehurefu hwemaoko kumativi ese etsvimbo yekusunda chinonzi ratio yeruoko rwerocker, inova inenge 1.2 ~ 1.8. Mugumo mumwe weruoko rurefu unoshandiswa kusunda vharuvhu. Nzvimbo yekushanda yemusoro wetsvimbo yekusunda inowanzogadzirwa nechimiro che cylindrical. Kana tsivimbo yekusunda ichitenderera, inogona kutenderera pamucheto wetsvimbo yekusunda, kuitira kuti simba riri pakati pezviviri rigone kushanda padivi pevharuvhu kusvika pazvinogoneka. Ruoko rwerocker runoboorwawo nemafuta ekuzora uye maburi emafuta. Skuruu yekugadzirisa yekugadzirisa clearance yevharuvhu inoiswa mugomba rakarukwa pamucheto wetsivi pfupi wetsvimbo yekusunda. Bhora remusoro weskuruu rinosangana netii yakakombama pamusoro petsvimbo yekusunda.
Ruoko rwemuchina werocker haruna chinhu rwakaiswa parocker arm shaft kuburikidza nerocker arm bushing, uye rwekupedzisira rwakatsigirwa pachigaro cherocker arm shaft, uye rocker arm yakaboorwa nemaburi emafuta.
Ruoko rwerocker runochinja divi resimba kubva patsvimbo yekusundidzira rovhura vharuvhu.
