法。
　　（2）再道時針搖轉曲軸（從風機（Draught Fan）端看，逆發動機運轉方向），使皮帶(輪上的記號與齒輪室所刻記號之間的弧長恰好為58mm維修挖掘機對挖掘機進行定期的車輛清潔，

部件檢查潤滑以及對受損零件的更換和維修等內容，主要的目的就是為了有效地保證挖掘機的工作效果和良好

的技術狀態，避免出現由于零部件損耗而導致的故障發生，為人們的安全提供良好的保障修理挖掘機的舊車修理是在修理時對車上拆

下的總成、組合件及零件，凡能修復的，經修復后全部裝回原車。
　　（3）裝上高壓泵端面連接螺栓，排凈低壓(Low pressure)油路和柱塞內的空氣，將油門置于最大供油位置，用套筒順時針緩慢搖轉油泵軸，至1缸油面剛剛波動時停止轉動。
　　（4）按規定扭矩裝上油泵齒輪（Gear）上的三個緊固螺栓。 按這種辦法(methods)調整供油提前角關鍵在于1缸上止點的準確位置和1缸油面波動的瞬間，使用這種辦法只會使互缸上止點稍超前（因為5缸進氣門與4缸排氣(Exhaust)門重疊10o），從而造成供油提前角略小于28o，建議控制（control)弧長取60－65 m。（補償3o）。 3 關于測定(Assessment)軸瓦間隙的幾點看法 曲軸配瓦是發動機修理中的關鍵工序，有的修理工配瓦往往采用千分尺、量缸表測量單個軸頸度量軸瓦間隙。這種辦法往往會得出錯誤的結論，尤其對于燒過瓦或使用了十多年的老設備(shèbèi)。因為當軸承座孔（多缸機）的圓柱度接近0．05m
　　M、曲軸彎曲度接近0．05mm時，彎軸對不同心的座孔的相互位置，從圖2可以明顯地看到，盡管單個軸頸量得的間隙在正常范圍內，但每個軸頸的間隙就大不一樣了。雖然修理工的手感、軸瓦（bearing shell）的接觸痕跡能對配合間隙有感性認識，但沒有量化，不能作為重要的修理技術(technology)數據。 怎樣才能工序合理、可靠地配瓦、準確地度量軸瓦間隙呢？我認為，在修燒過瓦的工齡很長的發動機時，應先用量缸表、千分尺測得每道軸承孔及軸頸的圓柱度（有條件的話，最好檢測多缸機的座孔的偏心度大小及曲軸彎曲度大小），在保證各道軸承不發生卡滯、軸瓦背壓足夠的情況(Condition)下配瓦（若座孔橢圓度超差太多，分界面附近軸瓦刮得太多，會造成軸瓦松動、打轉而嚴重(serious)拉瓦）。當各軸瓦接觸印痕及曲軸輕重適合（無卡滯）時，在各道軸瓦對稱方向壓上0．5－0．7mm的保險絲（fuse)，再測量(cè liáng)保險絲厚度，可得出各道軸承的實際配合間隙。因為軸頸最大回轉半徑與瓦座偏心最大、最小處的擠壓，決定了保險絲厚度。顯然這種辦法已兼容了軸及座孔的不同心度，所以這是一種檢測軸瓦間隙的最客觀、最直接的辦法
