I muri i te turuturu o te hinu o te hiri o te porotiti, kāore he aha? I rongo ahau he mate noa iho, kāore hoki he hua o te whakatikatika? Kāore?
1. Kāore i te tūtohutia kia whakakapia mēnā kei te pirangi koe ki te huri noa, ki te whakawhiti i te hiri hinu, ka whakapiri anō i te kāpia;
2. Ehara i te mea kino rawa, kāore e hiahiatia kia kati. He mate noa te turuturu hinu o te pouaka miihini, he nui rawa.
3. Me whakakapi te huinga mīhini i te wā e whakakapia ana, ā, me tuarua te huinga mīhini kua whakakapia, koinei te ture ahumahi. Ka whakahokia te mīhini kua whakakapia ki te raina whakaputa hei whakahou me te tirotiro, ā, ka whakamahia motuhaketia mō te tiaki.
Ngā take mō te turuturu hinu o te hiri hinu o muri o te porowhita crankshaft
1. Kāore te hiri hinu o te porowhita e whakamahi i ngā hinu whakahinuhinu kāore i te hinu i roto i te tukanga pēhi, ka hua ake te wetekina o te hiri hinu, te taka rānei i muri i te whakamahinga o te mīhini mō tētahi wā (hei tauira, ka whakamahia e ētahi kaihanga mīhini te hinu hei whakakapi i ngā hinu whakahinuhinu kāore i te hinu te utu nui hei whakaiti i ngā utu hanga);
2. Ko te āhua ōrite o te pēhi i te hiri hinu ki te mata tāutanga o te nohoanga hiri hinu kāore e tutuki i ngā whakaritenga hangarau o ngā tuhi huihuinga, ka kore e ōrite te ahotea me te rerekētanga o te ngutu o te hiri hinu. I muri i te whakamahinga o te miihini mō tētahi wā, ka pakaru te hiri hinu me te turuturu hinu i te rerekētanga o te ngutu o te hiri hinu, tae noa ki te hē o te hiri hinu katoa.
3. He roa te ora o te miihini, ā, ka puta ngā kapiti i te ngutu o te hiri hinu kua tawhito haere, ka turuturu te hinu.
