I roto i te ao hangarau motuka, he mea nui te mahi a ia wāhanga hei pupuri i te rere pai o te miihini. He mea nui te mekameka wā engari he mea e warewarehia ana. Ko te whāinga o tēnei tuhinga he whakamārama i te kaupapa me te hiranga o te mekameka wā takirua, he matapaki i ōna painga me te take e whakamahia whānuitia ana i roto i ngā miihini o ēnei rā.
Kia mōhio ki ngā kaupapa matua:
I mua i te ruku hohonu ki te kaupapa o te mekameka taima takirua, me mārama koe ki tana mahi. Ka hono te mekameka taima i te porowhita me ngā porowhita kame, kia noho tahi ai. I te hurihuri o te porowhita, ka whakahaerehia e te mekameka taima te whakatuwheratanga me te katinga o ngā takirere miihini, ka whakahaere i te urunga o te hau me te wahie me te pana atu i ngā hau putanga.
He aha te mea e wehewehe ai te mekameka taima roera takirua:
Ahakoa e whai hua ana te mekameka wā paerewa ki tana mahi i whakaritea, ka whakanuia ake e te mekameka wā takai-rua. Ko te āhuatanga motuhake o te mekameka wā takai-rua ko tōna hoahoa, kei reira te mekameka e rua ngā rarangi o ngā takai iti e hono tahi ana. Kua hangaia tēnei hoahoa auaha hei whakaiti i te ngoikore me te whakaiti i te tūponotanga o te rahunga o te mekameka wā, kia tika ai te wā me te whakaroa i te roa o te ora o te miihini.
Te Pakari me te Kaha Whakarei:
Ko tētahi o ngā kaupapa matua o te mekameka taima takirua he aro ki te totoro me te pakaru o te mekameka. I roto i te wā, ka totoro pea ngā mekameka taima paerewa, ka hua ake he taima takirere hē, te ngaronga o te mana, me te kino pea o te miihini. I tetahi atu taha, ko te noho mai o ngā rarangi takirua o ngā roera i roto i te mekameka taima takirua ka tohatoha pai i te kawenga, ka whakaiti i te totoro o te mekameka, ka whakanui ake i tōna roa whānui.
Whakapai ake i te tika o te wā:
I roto i ngā mahi tino pai, he mea nui te wā tika hei whakapai ake i te mahi a te miihini. He tino pai ngā mekameka wā roera takirua ki te pupuri i te wā tika o te takirere nā te mea i hangaia hei whakaiti i te ngoikore o te mekameka. Mā te whakaiti i te tūponotanga o te ngoikore, ka whakarite ngā roera takirua kia noho tahi tonu te poro crankshaft me te camshaft, ka whakapai ake i te pai o te miihini me te putanga mana.
Whakaitihia te haruru me te wiri:
Ka taea e te wiri me te haruru o te mekameka te whakararuraru i te miihini, ā, ka pā ki te wheako taraiwa whānui. Ko tētahi atu painga o ngā mekameka taima takirua ko te kaha ki te whakaiti i ngā wiri nā te nui haere o te mata pa e whakaratohia ana e te hoahoa o te roera. Nō reira, ka tino whakaitihia te haruru me te wiri o te miihini, ka āwhina i te miihini kia oma pai, kia marino hoki.
He mea nui te mahi a ngā mekameka taima takahuri rua i roto i ngā hoahoa miihini hou, e whakarei ake ana i te roa, e whakapai ake ana i te tika o te taima, e whakaiti ana hoki i te haruru me te wiri. Mā te hoahoa takahuri rua ka whakatau pai i te raru o te totoro o te mekameka, e whakarite ana i te tika me te pono. Nā ōna painga me te whakamahinga whānui i waenga i ngā kaihanga motuka, ko te kaupapa o te mekameka taima takahuri rua he mārama ki te whakapai ake i te mahi me te roa o te miihini. Nō reira, i te wā e tīmata ai koe i tō miihini, kia maioha ki te pai me te pono o te mekameka taima takahuri rua ki tō waka.
