Lokhu kusethi yegiya le-Worm Wheels elisetshenziswe esikebheni. Izinto ezibonakalayo 34Crnimo6 ye-Worm Shaft, ukwelashwa kokushisa: I-Carbulization 58-62HRC. I-Worm Gear Gear Material Cusn12PB1 Tin Bronze. Igiya lesondo le-Worm, elaziwa nangokuthi igiya le-Worm, luhlobo lohlelo lwegiya oluvame ukusetshenziswa ezikebheni. Kwenziwa isibungu se-cylindrical (esaziwa nangokuthi isikulufa) nesondo lomfokazi, okuyigiya le-cylindrical elinamazinyo asikiwe ngephethini elinomoya. I-Worm Gill Giar meshes nge-Worm, yakha ukudluliswa kwamandla okubushelelezi futhi okuthule kusuka ku-shaft yokufaka kuya emgodini wokuphuma.

Ezikebheni, amagiya wesondo elinamasondo ajwayele ukusetshenziselwa ukunciphisa ijubane le-apopeller shaft. Igiya lezibungu linciphisa ijubane le-shaft yokufaka, evame ukuxhumeka enjini, futhi idlulisela lawo mandla
