Where is the dowel pin on a Cummins 12v engine?
Despite the brutal reliability of the 5.9 Cummins 12v, it does have one fatal flaw. The 12v has a dowel pin that sits on the front of the engine. The pin is responsible for ensuring proper alignment of the timing cover, and is made of steel. Engines experience “heat cycles” which is the basic heating and cooling of the engine.
What to do if your Cummins overflow valve is bad?
Each one of these known issues results in reduced fuel pressure. When fuel pressure decreases, overall engine performance decreases as the cylinders do not get an adequate amount of fuel. The best replacement option for a bad P7100 overflow valve is replacing the valve with a Tork Tek adjustable overflow valve.
Where is the spring on a 12 valve Cummins Engine?
This is a special banjo bolt with a spring and ball inside that regulates the fuel pressure inside the injector pump. It is located between the engine and the injector pump. Take the valve out and shake it. If the spring is broke it will rattle. If it looks like this one, you can take it apart and add or remove shims to adjust the pressure.
What should fuel pressure be in a 12 valve Cummins Engine?
If your supply fuel line is loose, it is possible to draw air into the fuel system at that point, so if you suspect you are not getting rid of the air in the system check your supply line connections. These engines should have between 18-30 psi or more of lift pump fuel pressure.
