I-T86 Chwetheza umsasazi wobugcisa, okwabizwa ngokuba ngumhambisi wobuninzi bokuhambisa umsasazi, oko kukuthi, i-arhente yeoyile yeoyile ehanjiswa yi-piston kwindawo yokucoca, kwaye iarhente yeoyile igcinwe kwindawo yemitha Igumbi eliphelelwe lixesha licinezelwe ngamandla kwindawo ye-yebrice, kwaye iarhente yeoyile iphinde igcinwe - igcinwe kwigumbi emva kwenkqubo Ukungalayishwa ukulungiselela umsebenzi olandelayo.Inkqubo kufuneka isebenze ngethuba kunye nempompo ye-commation ehambelana nayo kufuneka ibe nomsebenzi wokukhupha. Kumjikelo wokusebenza, iinxalenye ezinamathelisi kuphela, kunye nomgama, kufutshane, ukufakwa kwezinto ezinamajelo angenasiphumo ekufuduseni. Inqanaba elichanekileyo, isenzo esivakalayo, ioyile yeoyile egudileyo. Jonga i-valveves kuthintela i-oyile ekhaya.
