He wāhanga te camshaft o te mīhini piston. Ko tana mahi he whakahaere i te mahi whakatuwhera me te kati o te takirere. Ahakoa ka huri te camshaft i te haurua o te tere o te crankshaft i roto i te mīhini wha-whiu (ka huri te camshaft i te tere ōrite ki te crankshaft i roto i te mīhini rua-whiu), he tere te huri o te camshaft, ā, he nui te taipana e hiahiatia ana. Nō reira, me nui te kaha me te tautoko e hiahiatia ana mō te hoahoa camshaft. He mea hanga i te nuinga o te wā ki te maitai koranu kounga teitei, ki te maitai koranu rānei. He tino nui te mahi a te hoahoa camshaft i roto i te hoahoa mīhini nā te mea e pā ana te ture nekehanga takirere ki te mana me ngā āhuatanga mahi o te mīhini.
Ka pāngia te porowhita camshaft e ngā kawenga pānga ā-wā. He tino nui te ahotea pa i waenga i te CAM me te turtet, ā, he tino teitei hoki te tere reti, nō reira he tino kino te kakahu o te mata mahi CAM. I runga i tēnei āhuatanga, me tino tika te āhua o te porowhita camshaft me te mata mahi CAM, me iti te taratara o te mata, me tino pakari hoki, engari me tino ātete kakahu me te pai o te hinu whakahinuhinu.
Ko ngā camshaft he mea hanga i te maitai waro kounga teitei, i te maitai koranu rānei, engari ka taea hoki te whakarewa i te rino koranu, i te rino pūwero rānei. Ka orohia te mata mahi o te journal me te CAM i muri i te maimoatanga wera.
