Crankshaft bending deformation: ʻAʻole pono ma mua o ka 0.04 ~ 0.06mm ka hewa runout radial. Crankshaft journal: ʻAʻole ʻoi aku ka nui o ka pōʻai a me ka cylindricity hewa ma mua o 0.01 ~ 0.0125mm.

(1) E koho i ka micrometer waho me ka laulā kūpono e like me ka crankshaft journal

(2) E ana i ka nui o ka lole ma ka crankshaft nui puke pai a me ka hoʻohui lāʻau puke me ka waho micrometer e like me ke kānāwai o ka lole, a helu i ka poepoe a me ka cylindricity hewa. E ana mua ma na aoao elua o ka puka aila puke pai, a laila koho 90° e ana hou. Koho ʻia ʻelua ʻāpana no kēlā me kēia puke pai, a koho ʻia kēlā me kēia ʻāpana ma kahi o 1/3 o ka lōʻihi o ka puke pai.

(3) ʻAʻole ʻae ʻia nā māwae transverse ma ka ʻili o ka puke pai o ka crankshaft. No nā māwae transverse, inā ʻo ka hohonu i loko o ka nui hoʻoponopono puke pai, hiki ke wili ʻia ma ka wili ʻana, i ʻole e ʻoki ʻia.

(4) Inā ʻoi aku ka nui o ka pōʻai a me ka cylindricity hewa o ka crankshaft engine ma mua o 0.025mm, pono ia e lepo a hoʻoponopono ʻia e like me ka nui o ka hoʻoponopono ʻana. 3. Ua maheleia ka crankshaft journal repair o Santana a me Jetta engines i ekolu pae o ka hooponopono ana, me hookahi pae no 0.25mm.

(5) He ʻokoʻa nā mea o ka crankshaft, a ʻokoʻa nā koi o ka hana i ka wā o ka hoʻoponopono anu. E mālama pono i ka haki ʻana o ka crankshaft a i ʻole nā ​​māwae hou.

(6) E noʻonoʻo e hoʻokaʻawale i ka pilina ma waena o ka hewa o ka pōʻai radial runout o ka puke pai, ka hewa pololei o ke axis crankshaft, a me ka curvature.

(7) I ke ana ana i ka nui o ka crankshaft journal, roundness a me cylindricity hewa, pono e hoohuoi ia me ka lua aila.
