1. ʻenekini kaʻa:

ʻO Camshaft, pulley timing crankshaft, pauma wai, pulley ʻaila pauma, nā mea nui a me nā mea i hoʻokele ʻia, nā sprockets nui a me ka hoʻokele ʻia, nā kāmeka, nā pāpale halihali, nā lima rocker, nā lāʻau, nā pā pahu, nā alakaʻi valve, nā noho komo a me nā pahu pahu, pahu pahu kaʻa.

2. Kiekie a me haahaa ka māmā holo mīkini hana hubs a me nā mea, clutch gears, cams, camshafts, sliders, shift levers, bushings, alakaʻi poloka, synchronization apo, kaʻa kaʻa.

3. Na ea a me na mea e ae, na sprockets, maiuu hoomaka, ratchet, star gears, double gears, auxiliary gears, transmission gears, push rods, cams, bushings, sliding bearings, centering sleeves, driven discs, advances Valve seat, automobile, motorcycle oil pamu;

4. ʻO nā pahu ʻaila pauma like ʻole, nā rotors pauma aila like ʻole, nā apo cam, nā kaʻa a me nā mea hoʻoheheʻe kaʻa kaʻa, nā pistons like ʻole, nā noho valve lalo, nā noho alakaʻi, nā piston compressor, nā poloka pahu, nā poʻo cylinder, nā pā valve, nā apo hoʻopaʻa, nā lima lima like ʻole, nā rotors, nā mea hana ʻoihana mahiʻai, a me nā mea ʻē aʻe: nā mea hoʻolaha, nā mea hoʻokele honua, nā pā kīʻaha o loko, nā hui kūloko i hui ʻia, nā nati kila kila a me nā pou magnetic.

Mai ka hoʻonui ʻia ʻana o ka nui o nā kaʻa a me nā kaʻa i nā ʻāpana pauka pauka, hiki ke ʻike ʻia aia ka pauda metallurgy gears i kahi kūlana wikiwiki i nā ʻāpana pauda pauda.
