Kotahi anake te rerekētanga, he rerekē te maha o ngā wāhanga. He taurite te maha o ngā wāhanga o te whitiki katoa o te mekameka, ko te whitiki haurua ia he taukē te maha o ngā wāhanga.
Hei tauira, ko te wāhanga 233 e hiahiatia ana he whitiki katoa, ko te wāhanga 232 ia e hiahiatia ana he whitiki haurua. Ko te mekameka he momo whitiki mekameka e pā ana ki te wāhanga katoa, arā, he wāhanga katoa o te mekameka, ka taea hoki te kī he whitiki katoa. Ko te haurua mata e pā ana ki te haurua o te whitiki mekameka, ko te tikanga he haurua mekameka, ā, ka taea hoki te kī he whitiki haurua.
Kāore e taea te whakarerekē i te tawhiti o waenganui ina kei runga i te sprocket, ā, ki te kore e totoro te sprocket, ki te tino wetekina te mekameka, ki te ngaro rānei tetahi wahi, mā te tango i tētahi hononga ka poto rawa, mā te tāpiri i tētahi hononga ka ahua poto rawa. Ki te roa rawa, ka taea te whakamahi i te mekameka hei hono i waenganui.
