4. Imbobo ye-shingle yokuphotha nge-Ding enqabeni enyakatho ye-4 at.Noma ngenxa yokubhula, ipiston ilayishwa kusilinda bese kushiswa amafutha.'Okwamanje kufanele kubhekwe ukuthi kungani i-piston bias cylinder, kuze kube i-piston ingena kusilinda ngemuva kokungachemi kuze kube manje.

5. I-crankcase kanye nomkhathi wangaphandle wezwe ngaphandle kwe-word assembly tilt position skew ayifakiwe;Iphedi yephepha lekhava yekhanda lesilinda aliqinile ngoba isikulufu sokubopha esitshekile asifakiwe futhi nepani likawoyela aliqinile.Ngokusobala izokhiqiza isenzakalo senani lokucindezela okungekuhle kwe-crankcase, ngakho-ke kuzoba nokuvuza kwamafutha phansi kwefasitela lesisetshenziswa sokuphefumula.

6. Ngemuva kokuthi ipuleti lasentwasahlobo epuleti eliphansi lezinto zokuphefumula likhubazekile, noma kukhona isihlabathi somlotha nezinye izinto engxenyeni engezansi yepuleti lasentwasahlobo, ukuze intwasahlobo ingabuyeli endaweni yokuqala, noma ukuqina ipuleti lasentwasahlobo liqine kakhulu, lizobangela ukuvuza kwamafutha.Ngalesi sikhathi, izingxenye zemishini yokuphefumula kufanele zihlanzwe noma zishintshwe.

7. Ngemuva kokuthi injini ye-diesel isetshenziswe isikhathi eside, i-piston ring elasticity iba buthakathaka noma imvume yokuvula iyanda, kanye nokwenyuka kwe-cylinder liner kanye ne-piston clearance, okuzokwenza ukuthi imishini yokuphefumula ivuze uwoyela, bese izingxenye zokugqoka. kufanele kushintshwe.

8. Uthuli nemfucumfucu kuvimbe imbobo yokubuyisela uwoyela engu-1 mm epuleti elingaphansi le-respirator, okubangela ukuthi umshini wokuphefumula ungakwazi ukubuyisela amafutha, futhi amafutha avuza efasiteleni lesimshini wokuphefumula.Ngalesi sikhathi, izingxenye zomshini wokuphefumula kufanele zihlanzwe.

9. I-screw yokubopha ye-respirator ayiqinisiwe, futhi ukukhanya kwesembozo sokuphefumula kubi kakhulu, okuholela ekuvuzeni kwamafutha ephepheni lephepha.Kulesi simo, qinisa isikulufu, shintsha ikhava yokuphefumula noma usebenzise i-sealant ephepheni lephepha.
