(1)缸盖螺母未拧紧 S195柴油机缸盖螺母扭紧力矩为240～280牛顿·米,S1100柴油机缸盖螺母扭紧力矩为260～300牛顿·米。若安装时拧紧力矩太小,易造成水箱内冒气泡、机油中进水和压缩系漏气的故障。新机或修后的柴油机,使用一段时间后,应重新拧紧缸盖螺母。 (2)缸垫冲坏或烧坏因缸盖螺母扭矩太小,装配时机体平面、缸垫和缸盖平面处沾有硬质物,操作时经常猛加油门等都易造成缸垫冲坏或烧损,引起水箱冒气泡的故障,此时,应采取相应措施予以排除。 (3)缸垫长期使用后密封性差这时应更换新缸垫。 (4)缸套破裂缸套破裂与装配质量关系极大(装配后开裂的裂纹通常在缸套
(1) The head nut is not tightened The torque of the S195 diesel engine cylinder head nut is 240 to 280 Nm. The torque of the S1100 diesel head nut is 260 to 300 Nm. If the tightening torque is too small when installed, easy to cause bubbles in the water tank, oil in the water and compressed air leak failure. After a new engine or repaired diesel engine, after a period of time, should re-tighten the cylinder head nut. (2) cylinder pad washed or burned out due to the cylinder head nut torque is too small, the body plane assembly, cylinder pad and cylinder head surface stained with hard material, often fierce operation of the accelerator, etc. are likely to cause cylinder pad damage Or burning, causing the bubble tank bubble failure, this time, should take appropriate measures to be ruled out. (3) after the long-term use of cylinder head gasket poor sealing should replace the new cylinder pad. (4) cylinder liner rupture and assembly quality is very large (crack cracking after assembly usually in the cylinder liner
