Ua luhi loa ka puke pai o ka crankshaft a me ka lāʻau, a he mea maʻamau ke hoʻopaʻa liʻiliʻi ʻia ka puke kiʻi camshaft.

ʻO kahi papa inoa pōkole penei:

1. ʻO ka pilina ma waena o ka wikiwiki o ka crankshaft a me ka māmā camshaft ma ke ʻano he 2:1, ʻo ka wikiwiki crankshaft he 6000rpm, a ʻo ka wikiwiki camshaft he 3000rpm wale nō;

2. ʻOi aku ka maikaʻi o nā kūlana hana o ka crankshaft. Pono ka crankshaft e ʻae i ka ikaika i lawe ʻia e ka neʻe ʻana o ka piston, e hoʻohuli iā ia i torque, a e hoʻokele i ke kaʻa e neʻe. Hoʻokele ʻia ka camshaft e ka crankshaft a hoʻokele i ka valve e wehe a pani. He okoa ka ikaika.

3. He mau pads ko ka crankshaft journal, a aole he mau pad o ka puke pai camshaft; ʻoi aku ka liʻiliʻi o ka ʻokoʻa ma waena o ka puke pai o ka crankshaft a me ka puka ma mua o ka pukana camshaft a me ka puka. Hiki ke ʻike ʻia ʻoi aku ka ʻino o ke kaiapuni o ka crankshaft journal.

No laila, hiki ke hoʻomaopopo ʻia ua ʻeha loa ka crankshaft a ua luhi iki ka puke pai camshaft.

No ka mea, ʻaʻole au i ʻike i nā kiʻi o ka lole koʻikoʻi, hiki iaʻu ke kamaʻilio pōkole e pili ana i nā kumu kūpono. No ka laʻana, ʻaʻole maikaʻi ka coaxiality o ka pāpale halihali nui, e hopena i ka ʻaʻahu ʻokoʻa o ka puke pai a me ka lāʻau bearing; haʻahaʻa ke kaomi aila, a ʻaʻole lawa ka kiʻiʻoniʻoni aila ma ka puke pai, hiki ke ʻaʻahu like ʻole.
