Brilliant video just wish I was a bit closer I’m gonna have a go at this myself bought myself a pressure tester just waiting for it to be delivered I’m in the UK ito have the injectors recondition by a shop is £150 an injector to buy the nozzles they’re £50 for 4

@@garethcorlett4054 thank you Sir! That is a ridiculous price for diesel injectors. For the price of 1 injector you can buy the tool. I did buy the “genuine” quality injector nozzles. They worked pretty good.

Excellent video yes I bought the pump pressure tool for £50 +£5 postage

I can sense the smell of diesel all the way to here! Stay awesome Cory! 🇸🇪🇺🇸

[@conrad1468]

Oh the smell was quite delightful!! 😀 Thank you Sir!!

@@conrad1468 Yes! And impossible to wash off. 😁

Great video, thanks. Surprisingly simple inside... time for me to man up and get on with it!

[@conrad1468]

Thank you Sir! I’m glad it inspired you Man up!! 😀 If you have any questions let me know.

[@icedog75]

It's a balance between the proper pressure and pump cam wear...you want to be pretty darn close to design pressure so you don't have accelerated wear on the pump...

[@conrad1468]

That’s an excellent point. Didn’t think of that. Thank you!!

Hi Cory! If my 2a was a Diesel I’d take you up on your offer! My ‘64 is a 2.25 gas variant! Nice video!

[@conrad1468]

Thank you Sir! I’d gladly help anyway I can. 😀

Great video Cory. I remember using what looks to be an almost identical injector tester when I worked on ALCO diesels 20 years ago as an apprentice. We used to spray onto a piece of blotting paper and check the spray pattern against the ideal pattern in the manual. You could pick up blocked or worn spray holes that way. From memory the ALCOs had 10 (maybe 8?) holes per nozzle so the spray pattern looked like a daisy and each 'petal' needed to have a similar shape, length and density. Anyway, I suppose if you are still getting fouled injectors, the next step would be the pump to ensure that each injector is getting the same amount of fuel, but it might pay to check the cylinder compression too. Worn rings or poorly seating valves can give you headaches there. The metal you found in the injector is a bit worrying! Hopefully it's just debris from the inside of the fuel pipes. Thanks again for the video Sir, I'm sure that it will be helpful for those with older diesel engines!

[@conrad1468]

Thank you Sir! The diesel rebuild shop has the same tool along with pump testers. Old school shop. No need to change what works right?!?! Interesting about the spray pattern on paper. That would answer explain a lot. In my future videos I’ll will be addressing some of those issues you suggest. We dive deep!! 😀 The little pieces of metal are from the metal hoses. It was on the threads. So I made sure to clean and use compressed air to clean the lines.

on the injector where the 2 pins are the flat surface will get hammered from the needle . the tip on the nozzle will also be come damaged and bolge out .

[@conrad1468]

Thank you for the info.

[@ingmarthomas9502]

Great video! Gonna refresh my injectors soon. Which nozzles are you using?

[@conrad1468]

Thank you Sir! They are OEM quality BritPart 247726G nozzles. A little bit more money per nozzle but I feel it’s better to a little more for the “genuine” version of parts.

Really enjoyed the video, feel confident about doing my own. Looking at your engine it looks like the 2ltr oil filler which has push on cap. 2.25 I believe had a radiator type. On no 4 injector spill pipe, does that go direct back to tank and/ or also back to filter. Many thanks

[@conrad1468]

Thank you Sir! It’s an early Series 2A. It shares many parts with Series 2. Maybe that’s why a lot of part look earlier. You are correct. The return line goes to the tank and fuel filters. The fuel filters return line on the filter housing has a tiny orifice. So major of the fuel returns to the fuel tank.

Hello Cory, testing my injector but fuel comes through top of injector, any idea why, also did you say you slacken of the pressure knob before pumping. Thanks Rob

[@conrad1468]

Hello Rob, come out of the top of the injector instead of popping and spraying or is it both at the same time? I actually raised the pop pressure by turning the adjuster in. One it cleared out the air and any particulars. I turned the pop pressure down to the proper specs.

[@robertpoole5305]

@@conrad1468 Hello Cory, thanks for prompt reply and my apologies for not saying how much I enjoy your videos, very clear and concise. I bought a reconditioned injector and that pops fine at 2000. The one I took out, cleaned etc pops at about 1000 but then nothing. Trying to adjust higher, nothing diesel from top and bottom. Screwdriver head adjustment not hex. So to sum up, mist at 1000 , nothing after. Thanks Rob (UK)

[@conrad1468]

@@robertpoole5305 thank you for the positive words. That’s bit of an odd spray pattern. I’m not sure why it’s acting opposite as normal. I’m guessing the cleaned nozzle might be worn. The high pressure is pushing the needle against the side and it won’t let the needle slide. The needle should spin easily and smoothly by hand when cleaning the nozzles. Low pressure let’s the nozzle vibrate easier than high pressure since the nozzle is out of spec. That’s my guess…

@@robertpoole5305 best of luck. It’s difficult to analyze a problem without the part in hand.

[@garethcorlett2904]

Just a quick question what is the problem if it’s leaking if it’s not holding pressure got new nozzles but one of them is not holding pressure what could the problem be I’ve stripped it down and cleaned it up and put it all back together but it’s still not holding pressure any help would be much appreciated thank you 👍🏻

[@conrad1468]

@@garethcorlett2904 sounds like a faulty new nozzle. Take it apart and give it another cleaning. Maybe I piece of dirt is in there? Is it leaking before the pop pressure is reached?
