Usoro ntinye bụ nke a:

1. Mbụ chọta crankshaft na mkpakọ n'elu nwụrụ anwụ center nke a cylinder, na e nwere a bolt n'ihu n'akụkụ aka ekpe nke engine ngọngọ. Wepu ya ma wụnye bolt dị ogologo. Mgbe crankshaft na-agba ọsọ ruo n'elu ebe nwụrụ anwụ nke cylinder, a na-agbanye bọtịnụ ahụ na crank, nke mere na crankshaft na-agbanye elu mgbe ọ na-agba ọsọ na elekere.
2. Mgbe ahụ dozie camshafts na-abata ma na-apụ apụ, enwere oghere na azụ azụ nke camshaft, na ọdịiche ahụ bụ eccentric. Tụgharịa camshaft ruo mgbe ọdịiche ahụ dabara na ụgbọ elu akara nke isi cylinder, wee chọta oghere oghere nke otu ọkpụrụkpụ ma tinye ya na oghere ahụ.
3. Wụnye ụdọ oge na oge nhazi oge, ma wụnye ya na ntụgharị ntụgharị mgbe ewepụrụ ya. Mepee bolts na-edozi oge ezé cam iyuzucha iji nye ohere ntụgharị efu n'etiti ezé oge ikuku cam na camshaft. Wụnye efere ntụzịaka na ihe nrụnye agbụ, wee hapụzie ihe nrụgide oge ekpochi akpọchi.
4. Enwere oghere nkedo na mkpuchi oge, jiri bolt kwesịrị ekwesị (M6X1.0) dozie eriri eriri crankshaft na mkpuchi oge. N'oge a, kpochie eriri crankshaft pulley bolts.
