Gawo lomwe limagwiritsa ntchito kuwonjezera mafuta ndikuwonetsetsa mafuta, kukakamiza mafuta pamtunda uliwonse. Mtundu wamtundu wa gear ndi rotor mtundu wamafuta amagwiritsidwa ntchito kwambiri mu injini zamkati. Mtundu wa mafuta wamafuta ali ndi maubwino osavuta, pokonza zodalirika, kugwirira ntchito kwapamwamba, kupamporo kwamtundu wamoto, ufa wamphamvu kwambiri. Pampuyi imakhala ndi maubwino omwewo pampu yofananira ndi mitundu yosiyanasiyana, yochepa kwambiri
Ntchito yosalala, phokoso lotsika. Kupukuta kwa color korona ndi kunja dzino limodzi, pomwe amayenda pang'ono, kuthamanga kwa dothi kumayenda mosavuta mkhalidwe wamkati wa fotor, motero, mawonekedwe awiri a rotor amavala pang'ono. Chifukwa envelopu, ya chipinda chozizira cha chipinda cham'madzi ndi chipinda chachikulu, pafupi ndi 145 °
