(1) Nui a liʻiliʻi paha ka ʻae ʻana o ka hui pū ʻana.
(2) Ke hoʻololi nei ka mamao waena ma waena o ka lua hili nui crankshaft a me ka puka pahu pahu camshaft i ka wā e hoʻohana ai a hoʻoponopono paha, e lilo i mea nui a liʻiliʻi paha; ʻAʻole like nā laina waena o ka crankshaft a me ka camshaft, e hopena i ka maikaʻi ʻole o ka hui ʻana.
(3) Ka hana pololei ʻole o ka ʻaoʻao niho niho, deformation i ka wā o ka mālama ʻana i ka wela a i ʻole ka ʻaʻahu nui ʻana ma ka ʻili niho;
(4) Ka ho'ololi 'ana o ke ka'a--'A'ole like 'ole ka 'awa ma waena o nā āwaha nahu i ka pō'ai a i 'ole ke 'oki 'ia;
(5) Aia nā ʻōpala, delamination a i ʻole nā ​​niho haki ma ka ʻili niho;
(6) Ua hemo a i waho paha o ka crankshaft a i ʻole camshaft;
(7) He nui loa ka holo ʻana o ke alo o ke alo a i ʻole ka puka radial;
(8) He nui loa ka ʻae axial o ka crankshaft a i ʻole camshaft;
(9) ʻAʻole i hoʻololi ʻia nā kāʻei ʻelua.
(10) Ma hope o ka hoʻololi ʻana i ka crankshaft a me ka pahu camshaft, ua hoʻololi ʻia ke kūlana meshing gear.
(11) Ua hemo ka nati hoʻopaʻa ʻana i ka manawa camshaft.
(12) Ua haki nā niho o ka pahu hoʻonohonoho camshaft, a i ʻole ua haki ka mea hana ma ke kuhikuhi radial.
