DK28 diesel Engine Parts Company introduces the precautions for connecting rod bolt installation
Connecting rod bolt refers to the fastener that the bolt head and the screw are connected together, which needs to be used together with the nut.
Matters needing attention
In order to prevent deformation or fracture caused by improper installation of connecting rod bolts, the following points should be paid attention to during installation:
(1) 、Before installation of Marine diesel engine accessories, carefully inspect and clean the appearance, and check the match between bolts and nuts, there should be no jamming and loosening phenomenon.
(2) 、The method of tightening bolts and the size of pretightening force should be carried out according to the diesel engine specification. Because the preload is too large or too small, and the preload of each bolt is not uniform, the reliability of its work cannot be guaranteed.
(3)、maintenance can not arbitrarily exchange the connecting rod bolt and its original assembly hole relationship, because the connecting rod bolt and the assembly hole is a transitional fit, need to use a small hammer gently knock into the bolt, random exchange will affect the fit relationship, too tight, too loose affect the reliable work of connecting rod bolt.
