It's so difficult When changing from a small pump to a large pump, other minor parts will likely need to be replaced as a whole.

Thank you for your advice. I will try to keep my work surface clean.

If it is fixed at 30 bar, it seems that the oil is leaking out somewhere. If it is a pump problem, the following can be inferred. 1. Piston sticking 2. sticking ball on the upper 45t nut side 3. sticking check valve 50t nut on the piston side. 4.imv valve sticking If it is not a pump problem, excessive backleak may occur in the injector.

@@nos00 thank you for answering! I have another question if you don't mind, does the testing machine you use in the vide control the fuel pressure regulator?, all the plungers seems to be working in my pump but it doesn't build enough pressure, could it be because I'm spining it with a drill and the fuel pressure regulator isn't connected?

The fuel pressure regulator is attached externally to the equipment. Since the inlet metering valve is inspected individually, it is not necessary for flow testing.

@@nos00 in my case my pump only has a fuel pressure regulator, it doesn't have a inlet metering valve

450

O-ring hardening, Oil leak occurs

They will sell a lot of nitrile gloves?

Just test $80

We sell both refurbished and genuine pumps, but the shaft and roller cannot be ordered separately.

@@nos00 thank you very much!

The abnormal pressure generation in each piston area was due to carbon buildup. The main issue with this pump is the inlet metering valve, which is the most problematic component. Additionally, the internal carbon buildup can cause irregular pressure formation, and one of the pistons is constantly compressed, leading to weakened piston spring tension, which may prevent proper pressure buildup.

It seems like replacing the inlet metering valve on the high-pressure fuel pump would be a good first step to address the issue.

@@nos00The main problem that there no fault codes, I have already replaced fuel pump in the fuel tank and fuel rail with pressure regulator sensor only problem that is displayed is bad closing 6th injectorand now I will address it

​@@nos00 could you please help with part number you are talking about, much appreciated:-)

Not all the air was exhausted.

Urea water has entered the injector and has been sprayed. This video shows the process of thoroughly cleaning the urea water before rust can develop, as it causes rust to form quickly

@@nos00 THANKS. Can you replace them with Kia Sorento injectors?

UIL-DHS40040-NAA 200W 40KHZ AC 220V 50/60HZ We purchase and use a specialized cleaning solution made in Korea.

We use cleaning swabs for electronic cigarettes that are smaller than cotton swabs.

@@nos00 Thanks for the answer

thank you :)

It works fine.

Yes it is possible. Remove the key from the shaft

The equipment manufacturer created and provided it. It was made by modifying a flathead screwdriver.

Los valores de medición se obtuvieron a través de la capacitación o folletos proporcionados por el fabricante del equipo cuando se compró el equipo.

It seems like a pump issue. You might need to overhaul it. Alternatively, it could be an issue with the IMV (Injector Metering Valve).

4A010 = CP2(EURO3) 4A420 = CP3(EURO4) The generations are different.

Thank you for your response. I have a 2012 Porter and it has an old generation pump, and when I check it with the device, the code P1185 high pressure appears. If I replace it with the new generation, will it be fine, or is the electronic system defective? Knowing that the engine is running, but when you press the pedal, the engine stops. Thank you again

It's being sold in various places. part no. 7135-523

If the spring inside the IMV valve moves well, it doesn't need to be removed.

Wow, really? 😄

La presión está escapando de la cabeza y el motor se apagaba intermitentemente. gracias :)
