Marine diesel engine accessory - fuel injector pressure plate oil seal

Fuel injector pressure plate

One side of the pressure plate is flat, and the other side is an arc surface. When installing the DK28 diesel engine accessory, the arc surface should face the fuel injector body to ensure that the fuel injector is tightly pressed in the center without deviation. Otherwise, it is easy for the air to leak out from the installation seat hole. Oil seal

All oil seals, such as the crankshaft oil seal and the starter shaft oil seal, should have the side with the self-tightening spring facing the interior of the engine. If they are installed in the opposite direction, the seal in the crankcase will not be tight, causing oil leakage.
