小型柴油机气缸盖底平面翘曲变形后,会造成气缸漏气,经常烧坏气缸垫。所以在上紧气缸盖时,一定要根据各机型所规定的扭力及顺序,轮流分多次上紧螺母。防止一个螺母上紧后再上另一螺母,也要防止各个螺母松紧相差过大。同时,在拆卸气缸盖时也应等机器冷却后进行,按上紧时的相反顺序轮番多次逐渐松开,不要卸下一个再卸另一个。因为气缸盖的局部放松,也能促使底平面变形。在上紧气缸盖时,如果发现有螺母、螺杆滑丝,一定要更换或修好。不允许用加大其它螺母的扭力来代替这个螺母、螺杆所需的紧度的办法来解决。在气缸垫长期使用,已经压得很薄而失去绵软性,或个别地方破损后,要及时更换或修补,不允许用加大螺母扭力的办法压紧,因为 Small diesel engine cylinder head plane at the end of warping deformation, can cause the cylinder air leaks, often burn the cylinder pad. Therefore, when tightening the cylinder head, be sure to tighten the nut multiple times in turn according to the torque and sequence specified by each model. To prevent a nut tighten another nut on, but also to prevent each nut elastic difference is too large. In the meantime, when removing the cylinder head, wait for the machine to cool down, and then gradually loosen it several times according to the reverse order of tightening. Do not remove one and then unload another one. Because of the partial relaxation of the cylinder head, but also to promote the bottom plane deformation. When tightening the cylinder head, if there is a nut, screw thread, must be replaced or repaired. Do not allow to increase the torque of other nuts to replace the nut, screw the required degree of solution to solve. In the long-term use of the cylinder liner, has been thin and lose softness, or damaged in some places, to be replaced or repaired in time, not allowed to increase the torque of the nut compression, because
