How does the timing of an injection pump work?
When you adjust the timing, you can alter when the engine injects the fuel, therefore changing when combustion occurs. An injection pump is often driven indirectly from the crankshaft by chains, gears or a timing belt that also moves the camshaft.
What happens when you change the injection timing on a marine engine?
When you modify the injection timing of your marine engine, it affects many components. Advancing the system will cause diesel to inject into the cylinder sooner than usual, also causing the combustion phase to occur quicker. A timing advance shows the number of degrees before the piston reaches top dead center and ignition takes place.
How does fuel injection work on a GMC diesel?
Fuel is drawn through the diesel fuel conditioning module (8), which combines a water separator, hand operated fuel prime pump, filter element and then through a fuel filter vacuum switch (9) to the fuel injection pump.
How much does an injection timing system cost?
When you combine all its properties, an injection timing system can make up about 30 percent of a diesel engine’s total costs. If you’re looking to advance the timing injection of your marine devices, you want to ensure the engine makes full use of the fuel injection process.
Where are the timing marks on an engine?
The timing marks are critical for use in the following diagnostics and repair: Replacing valve stem seals with the head on the engine There are two key locations with alignment marks. The first is located on your engine counterbalance and is marked of in degrees of rotation (usually in 5 degree increment marks.
Where are the timing marks on an OM616?
The second location is at the front of the camshaft right behind the sprocket. You will have to remove the valve cover to see these marks. There a a v notch cut in the spacer that sits on the end of the camshaft just behind the sprocket. On the forward cam tower there is a raised arrow as you see in the picture below.
When you adjust the timing, you can alter when the engine injects the fuel, therefore changing when combustion occurs. An injection pump is often driven indirectly from the crankshaft by chains, gears or a timing belt that also moves the camshaft.
What happens if the injection pump is too late?
Diesel that enters too soon or too late into the cylinder can result in excessive vibrations or severe damage to components. How you adjust the injection timing of the injection pump also depends on the type of marine engine you have and its age.

What do I need to change the timing on my diesel pump?
All you have to do is rotate the pump with a screwdriver and socket wrench — standard tools you can find in your garage or toolbox. You need to make sure you accurately measure the timing adjustment with a timer meter or probe for reading. Any small movement of the pump will cause massive timing changes.
When to change injection timing on a diesel engine?
Usually, injection timing is adjusted to create more power in the engine. Timing can be advanced to create more power. Sometimes, timing is adjusted in the opposite direction to fix a smoking or a lag problem. Can Injection Timing Be Adjusted On All Diesel Engines? Young or old, timing can be adjusted on any engine.

What are the symptoms of engine pump timing problems?
What are the Symptoms of Engine Pump Timing Problems? Incorrect fuel injection pump timing leads to reduced performance of the engine and can cause engine misfiring or other less obvious symptoms. It also causes over-consumption of fuel, excessive smoke production, loss of power and problems starting the engine as well.

How does a crankshaft camshaft position sensor work?
Since this type of Sensor only has two wires and no Power Supply, testing them is not that hard: One of the two wires is the Signal wire. Consequently, Sending the Signal to the Fuel Injection Computer or Ignition Module. The other wire acts as a Ground return.
