ʻO nā ʻāpana o ka crankshaft ka nui o ka puke pai a me nā ʻumi ʻumi o ka lāʻau hoʻohui. ʻO ka hoʻololi ʻana o ka neʻe pānaʻi o ka piston o ka ʻenekini ʻehā-stroke a me ka hoʻololi ʻana o ka crankshaft e hoʻopili ʻia ka crankshaft ma nā kihi like ʻole. Ua hoʻemi ʻia kēia friction i kahi pae haʻahaʻa ma lalo o ka hana a ka ʻaila lubricating.

Ke holo ka ʻenekini i ka wikiwiki a ma lalo o ka ukana kaumaha, piʻi ka mahana o ka lāʻau bearing a hoʻonui ʻia ka wela. No laila, pono e waiho ʻia kahi āpau ma waena o ka bearing a me ka bearing e pale ai i ka crankshaft. ʻAʻole hiki i ka ʻokoʻa ma waena o ka lāʻau a me ka nahele ke hōʻoia i ka holo ʻana o ka mīkini no nā ʻumi kaukani kilomita. Piʻi mālie ka nui o ke āpau me ke kau ʻana o ke kumu a me ke kāʻei.

ʻOiai ua pale ʻia ka crankshaft e ka ʻaila lubricating a me ka ʻae ʻana i ka lawe ʻana, i kekahi manawa ua pilikia ka crankshaft ma muli o ka lawa ʻole o ke kaomi aila, ka aila lepo, ka ʻae ʻana o ka lawe ʻana, ka ʻili pili ʻole ʻole, ka pau ʻole a me ka pololei.

Hiki ke nānā ʻia ka crankshaft o ke kaʻa me kahi paepae calibration, ka mea nui e ʻike i kona degere o ka buckling, hiki ke ana ʻia me ka papa hoʻohuli. Aia nō hoʻi ka ʻaʻahu o kāna puke pai nui a me ka puke pai lāʻau pili, hiki ke ana ʻia me ka micrometer. Na ka crankshaft e hana i ka lole puke puke i ka wā e hoʻohana ai, e hana ana i waho o ka puni a me nā cones. ʻO kēia ka mea e pili ana i kāna ʻano ʻike:

1. E holoi pono i ka crankshaft, o ka oi aku ka pono o ka mahele nana i ka aila, a o ke ana ana ma kahi o ka lua aila;

2. Ana o ka poepoe kaawale: E hoohana i ka micrometer o waho no ke ana ana i na kiko he nui ma ka pauku kea hookahi kahi i paa ai ka puke pai. anawaena a me ke anawaena li'ili'i.

3. Ana ke anawaena o ka cylindricity: ana helu he nui ma ka pauku longitudinal hookahi o ka puke pai, o ka hapalua o ka like ole ma waena o ke anawaena nui a me ka anawaena li'ili'i, 'o ia ke anawaena cylindricity.
