Precautions for the installation of marine diesel engine accessories
①Cylinder head gasket
When assembling, the curled side should face the cylinder head; if it is installed reversely, it will leak air and burn the cylinder head gasket early and affect its service life.
The horseshoe-shaped groove on the top or the peach-shaped tip on the top should face upwards; if it is installed reversely, it is not conducive to the mixing of fuel and air. The unburned fuel cannot produce secondary vortex motion and burn incompletely, causing the diesel engine to fail to start or start. Not working properly afterwards.
③Assemble connecting rod and piston
The oil hole at the small end of the connecting rod and the horseshoe-shaped groove on the top of the piston or the peach-shaped tip on the top should face upward on the same side; otherwise, the bushing at the small end of the connecting rod and the piston pin cannot be lubricated and dry friction is formed.
④The upper and lower tiles of the connecting rod tile
If it is a newly replaced bearing bush, the upper and lower bushes are not divided; if the bearing bush has been used, it should be installed in the original position, and the upper and lower positions should not be changed, otherwise it will affect the matching relationship between the journal and the bearing bush.
⑤ Combination of connecting rod cover and connecting rod
There are assembly marks on the big end of the connecting rod and the back of the connecting rod cover. Otherwise, the original machining accuracy of the large diameter of the connecting rod cannot be guaranteed, and the correct fit between the bush and the shaft will be damaged.
⑥Injector pressure plate
One side of the pressure plate is a flat surface, and the other side is a circular arc surface. When installing DK28 diesel engine accessories, the arc surface should face the injector body to ensure that the injector is centered and not deflected when it is compressed, otherwise it is easy to cause air leakage from the mounting seat hole.
For all oil seals, such as crankshaft oil seals, starting shaft oil seals, etc., the side with the self-tightening spring should face the body. If it is installed reversely, the seal in the crankcase is not tight, causing oil leakage.
