Hoʻopau ʻia ka hana ʻana o ka ʻenekini diesel e kēlā me kēia cylinder, no laila, ʻo ka ikaika e hana ana ma ka crankshaft he intermittent a me ke kaulike ʻole. I mea e hoʻokuʻu pono ai i kēia mau ikaika, pono e paʻa ka rotation o ka crankshaft ponoʻī. I mea e paʻa ai, pono e kaulike ka crankshaft. Pili ka crankshaft i ka hoʻonohonoho ʻana o ka helu o nā cylinders.

No ka crankshafts o ekolu-, eha-, elima-, a me ehiku-kuiuna diesel engines, koena kaupaona pono i ka crankshaft loaa ke koena kaumaha. Hoʻohālikelike ʻia ka nui a me ke ʻano o ke kaupaona kaulike i ka wā hoʻolālā. Hoʻopili ʻia ka hapa nui o nā kaupaona kaulike o nā crankshafts i ka crankshaft i ka wā e hoʻopaʻa ai a hoʻolei paha. I loko o hoʻokahi. Eia nō naʻe, hoʻopaʻa ʻia ke kaumaha kaulike o kekahi mau mīkini diesel i ka crankshaft. Ma muli o ka nui o ka nui o kēia ʻano pale kaulike, hoʻohana pinepine ʻia ka hoʻopaʻa ʻana i ka bolt inā ʻaʻole lawa ka wahi hoʻonohonoho.

No ka mīkini diesel ʻeono-cylinder me kahi kihi crank o 120, ʻoi aku ka maikaʻi o ka hopena kaulike. Me he mea lā ʻaʻole pono e hoʻokomo i kahi paona kaulike. Eia naʻe, ʻo kēia koena ka hopena o ka ikaika inertia ma ka crankshaft a i ʻole cylinder block. E like me ka mīkini diesel, aia nō ka nui o ka ikaika inertial, i kekahi manawa e hoʻonui ʻia ka halihali nui a i ʻole e haʻalulu ka pahu cylinder.

I mea e pale aku ai i kēlā mau hāʻule, ʻo kēlā me kēia ʻāpana o ka crankshaft he ikaika inertial nui, no laila aia nō kahi poloka kaulike. No nā mea kaupaona kaulike i hoʻopaʻa ʻia me nā bolts, i ka wā e pono ai ka crankshaft e hoʻoheheʻe ʻia, pono e hoʻoneʻe ʻia nā kaupaona kaulike e pale aku i ka hoʻokomo hewa ʻana mai ka haki ʻana i ke koena i ka wā e hoʻokomo hou ai.
