气缸套掉头是指气缸套从台肩下部整个裂掉。其主要原因有:1.气缸套靠台肩支撑在机体上,其台肩平面应高出机体上平面0.04～0.17毫米,如缸套高出机体上平面太多,当用274.4～313.6牛顿·米(28～32公斤力·米)的力矩上紧缸盖螺母时,会使缸套受压应力过大,而在支撑台肩下部产生裂纹折断;2.S1100柴油机是在S195柴油机基础上扩缸设计的,其缸套内径由95毫米扩为100毫米,所以两者的气缸垫不能通用。而有的用户将S195柴油机气缸垫错装到S1100柴 Cylinder sleeve U-turn refers to the entire cylinder liner from the bottom of the shoulder cracked. The main reasons are: 1. Cylinder liner supported by the shoulder on the body, the shoulder plane should be higher than the plane on the plane 0.04 ~ 0.17 mm, such as the cylinder liner above the plane too much, when used 274.4 ~ 313.6 Newton · M (28 ~ 32 kgf m) of the torque on the cylinder head nut, the cylinder sleeve will be subject to excessive compressive stress, but in the support of the lower shoulder crack generated; 2.S1100 diesel engine is based on the S195 diesel engine expansion Cylinder design, the liner diameter expanded from 95 mm to 100 mm, so both cylinder pads can not be universal. And some users will S195 diesel engine cylinder mistakenly installed to S1100 Chai Chai
