柴油機燃油油路分為低壓油路和高壓油路兩種。這兩種油路中的低壓油管和高壓油管出現漏油時，可采取“纏繞法”進行應急修理。當低壓油管出現漏油時，可先在漏油處涂抹黃油或耐油密封膠，挖掘機修理再用膠帶或塑料布纏繞在涂抹處，最后用金屬絲將纏繞好的膠帶或塑料布扎緊即可；當高壓油管漏油或凹癟嚴重時，可將漏油或凹癟處切斷，用膠管或塑料管把兩斷頭連接起來，再用細鐵絲扎緊即可；當高壓油管接頭或低壓油管接頭空心螺栓處漏油時，可用棉線纏繞在高壓油管接頭或空心螺栓處，挖掘機維修再涂抹黃油或耐油密封膠后擰緊即可。在柴油機的各個組成部件中，有些部件起著保護機器正常工作、提高效率以及延長使用壽命的作用。這些部件損壞時，可采用“部件短路法”進行應急修理。

當機油(you)濾清(qing)器(qi)(qi)(qi)損壞(huai)嚴重無法(fa)使(shi)用時(shi)，可(ke)將機油(you)濾清(qing)器(qi)(qi)(qi)拆(chai)除(chu)形(xing)成(cheng)“短路”，使(shi)機油(you)泵與機油(you)散熱(re)器(qi)(qi)(qi)直接(jie)連通應(ying)急(ji)使(shi)用。在(zai)采用此法(fa)時(shi)，應(ying)將柴(chai)油(you)機轉(zhuan)速控制在(zai)額定(ding)轉(zhuan)速的(de)80%左右(you)，并注意觀(guan)察機(ji)油(you)(you)(you)壓力。當柴油(you)(you)(you)濾清(qing)器損壞嚴重無法(fa)(fa)使用或暫無條件(jian)修復時(shi)(shi)(shi)(shi)，可(ke)(ke)將(jiang)輸油(you)(you)(you)泵出油(you)(you)(you)管(guan)與噴油(you)(you)(you)泵進(jin)油(you)(you)(you)接口直接連接應(ying)(ying)急使用。但(dan)事后應(ying)(ying)及時(shi)(shi)(shi)(shi)修復并安裝上濾清(qing)器，避免(mian)柴油(you)(you)(you)長時(shi)(shi)(shi)(shi)間不過濾造成(cheng)精密(mi)偶(ou)件(jian)磨損加劇(ju)。當機(ji)油(you)(you)(you)散熱器損壞時(shi)(shi)(shi)(shi)，也可(ke)(ke)采取“部件(jian)短路(lu)法(fa)(fa)”進(jin)行應(ying)(ying)急修理(li)，方法(fa)(fa)如下：拆(chai)(chai)下接在(zai)(zai)機(ji)油(you)(you)(you)散熱器上的兩根水(shui)管(guan)，用一膠管(guan)或塑(su)料管(guan)將(jiang)兩水(shui)管(guan)連在(zai)(zai)一起并扎緊，使機(ji)油(you)(you)(you)散熱器在(zai)(zai)冷卻系(xi)統(tong)管(guan)路(lu)中“短路(lu)”；拆(chai)(chai)下機(ji)油(you)(you)(you)散熱器上的兩根機(ji)油(you)(you)(you)管(guan)，去掉原來(lai)與機(ji)油(you)(you)(you)濾清(qing)器連接的那根油(you)(you)(you)管(guan)，將(jiang)另(ling)一根油(you)(you)(you)管(guan)直接與機(ji)油(you)(you)(you)濾清(qing)器連通。
