Ukukhishwa kwentuthu eluhlaza okwesibhakabhaka kubangelwa ukusha kukawoyela ngokweqile ekamelweni elivuthayo. Izizathu zalokhu kwehluleka yilezi ezilandelayo:

I-1) I-pan yamafutha igcwele amafutha. Amafutha amaningi azochaphaza odongeni lwesilinda kanye ne-crankshaft enesivinini esikhulu futhi angene egumbini elivuthayo. Isixazululo siwukumisa cishe imizuzu eyi-10, bese uhlola i-dipstick yamafutha bese ukhipha uwoyela oweqile.

2) I-cylinder liner ne-piston components zigugile kakhulu futhi imvume inkulu kakhulu. Uma igebe likhulu kakhulu, inani elikhulu lamafutha lizongena ekamelweni lomlilo ukuze lishise, futhi ngesikhathi esifanayo, igesi yokukhipha injini ye-crankcase izokhula. Indlela yokwelapha iwukuba esikhundleni sezingxenye ezigugile ngesikhathi.

3) Indandatho yepiston ilahlekelwa umsebenzi wayo. Uma ukunwebeka kweringi ye-piston kunganele, amadiphozithi ekhabhoni abhajwe emgodini weringi, noma izimbobo zamandandatho zisemgqeni ofanayo, noma imbobo yokubuyisela uwoyela iringi kawoyela ivinjiwe, inani elikhulu lamafutha lizongena Igumbi lomlilo nokusha, kanye nentuthu eluhlaza okwesibhakabhaka kuzokhishwa. Isixazululo ukukhipha amasongo e-piston, ukususa amadiphozithi ekhabhoni, ukusabalalisa kabusha izimbobo zamaringi (izimbobo zamaringi angaphezulu naphansi zinconywa ukuthi zinyakaziswe ngo-180°), bese ubuyisela amaringi e-piston uma kudingeka.

4) Ukuvuleka phakathi kwe-valve ne-duct kukhulu kakhulu. Ngenxa yokuguga, igebe phakathi kwakho kokubili likhulu kakhulu. Ngesikhathi sokuphuza, inani elikhulu lamafutha egunjini lengalo ye-rocker limuncwa egunjini elivuthayo ukuze lishiswe. Isixazululo ukufaka esikhundleni se-valve egugile kanye ne-conduit.

5) Ezinye izimbangela zentuthu eluhlaza okwesibhakabhaka. Uma amafutha emancane kakhulu, umfutho kawoyela uphezulu kakhulu, futhi injini ingasebenzi kahle, lokho kuzokwenza ukuthi amafutha ashise futhi akhiphe intuthu eluhlaza okwesibhakabhaka.
