How do you check the timing on a fuel pump?
By removing deflector from fuel pump
- Take out deflector on both sides of the fuel pump.
- Put hand torch on one side of pump and mirror on the other side.
- The light from torch will be visible on the mirror.
- Turn the engine so that the unit to be check is toward the TDC of compression (at plunger upstroke)
How do you time a dt466 injection pump?
It’s fairly easy, you line the crank up to the timing you want. Then pull a cover on front of the injection pump. When the cover is off loosen the 3 bolts and line the marks up in the peep hole by turning the gear. You don’t actually move the pump at all.
What is late injection?
marine. Retarded start of injection is a commonly used primary method for effective NOx emission reduction in the diesel engines and has negligible effect on fuel consumption when keeping injection duration conveniently short. See also Low NOx combustion.
What effect does pilot injection have?
As explained above, pilot injection increases the in-cylinder temperature and decreases the oxygen concentration of the in-cylinder gases before the main injection event. Both of these effects can increase soot formation.
What happens when the fuel is injected too early?
When fuel is injected too early in the cycle, ignition may be delayed because the temperature of the air charge in the cylinder is not high enough. This condition, of course, results in poor fuel economy, higher than normal exhaust gas temperatures, and smoky exhaust.
How to check fuel pump injection timing-diesel engine?
Diesel fuel injection pump timing issues are more common in older engines and might be more commonly experienced by owners of old roadsters, tractors or similar engines. If it is an older diesel engine with a mechanical fuel injection pump, you will need to check for the type of crankshafts, pipes, cylinders, gears etc of your model.

Can a diesel fuel pump injector be clogged?
Diesel fuel pump injectors are high-precision components. They also deal with a tremendous amount of motion and other stresses. One small visitor inside (a piece of dust, debris, etc.) can clog the injector. Worse yet, a microscopic object can leave the injector open all the time. If the injector can’t close, cylinder performance is compromised.
