    Fuel rails are a common rail injection thing. Lines in the top of the injectors are high pressure injector lines, line/couplers that connect injectors is the return line assembly

    It's a good idea to hold the injector steady with a spanner when you undo the feed pipes. I went to undo the feeds on our Jensen wood chipper and the injector turned slightly too which put a hairline crack in the bleed pipe's connection to the collar. Cleaned it up and silver soldered it back on, but would have been a problem if it had happened on site.

    Great video thank you, this really helps me. I am new to this and have the marine version of the Kubota D950 (Universal M25XP). It has a nasty what seems like vibration above 2k RPM and makes black smoke at that point. Someone on the dock said it sounds like a 'dead cylinder' caused by a bad or failing injector (comments/opinions are welcome and encouraged). I especially appreciated seeing that fuel rail come off in your video because I was looking at that on my engine wondering how in the hec those lines were fastened.

    Video was a great help of what to expect when removing the lines, EXEPT I cant get the lines of the fuel injection jump. It's like they are welded on (with rust) I've tried all the different penetrants for almost 2 weeks now. The fittings that goes into the pump are loose, but the injection lines won't budge. May have to cut the lines and remove the injector fittings to get a good grip on them to see if I can beat the lines off or heat would be safe to try then. Anyway, thank you for sharing how you removed your lines.

      @@rosincore Thanks for the tip, but that's what I've been doing, using a mallet. They are stuck on the fittings that are part of the injection pump. The problem is they (the pump fittings) are turning ( and the stuck injection lines turn with them) and kind of hard to keep them from turning while holding and beating the line connectors. If I don't succeed I'll cut the lines and place the pump fittings in a vice, then I could even use some heat? Hard to believe the are that hard to remove, but I can see they have had some rough handling in the past. Thank's again.

    I notice diesel leaking some where near the injectors. I thought it was where the injector screws into the head but I think perhaps it may be higher up where the fuel line are tighten on to the injectors.
    Is it possible for a leak to occur in either of those locations?

      There remains a small leak where one of the injector threads into the head but its so minor I will leave it as is and only monitor it.
      I would recommend to start with tightening the most accessible nuts/components first, even if they appear tight, and see if that solves the leak. There is a lot of work to get a spanner on the injector proper and it may not even be leaking there,

He is elderly and has no clue how mechanical things work. His deceased wife was the brains of the operation. The engine only has 225 hours on it. I drained the fuel tank (still had some diesel mixed with the gas) and flushed it out. Filled with fresh diesel fuel and new filter. Machine fired right up and ran great with no smoke. Gave the machine a good wash in the morning and immediately went to start it and it would not start. What do you think?

    • @rosincore
      @rosincore  Рік тому

      Heavy White smoke from a diesel engine is caused by the temperature being too low in the combustion chamber. This can happen when either there is raw diesel fuel that passes through to the exhaust, engine coolant is entering the combustion chamber, or the piston or other components are worn, damaged, or not correctly installed.
      Light white smoke could be due to A clogged fuel filter
      Low pressure in the fuel pump (Air in the fuel)
      Faulty or damaged injectors

I replaced the gasket but still had the same leak plus picked up a leak on one of the injectors. I replaced the two "O" rings on the injector and installed another gasket. I still have the leak, it loks like it might be oil with gas coming out. The motor tries to start a little but never does run plus the leak comes out at the gasket. Is there a chance that I am pressurizing the motor due to an injection pump leak and forcing the oil-gas out?

    • @rosincore

      sorry for the late reply... The unit was rolled over which requires in a diesel engine to pull all injectors and to rotate the engine to get rid of excess oil buildup in the cylinder so you do not bend a cylinder rod. Sames goes if you hydro lock a gasoline engine. You would pull the spark plug and rotate the engine. Hopefully the engine was shut off just before it sucked in any oil (water). I have saved many diesels this way.

      Make sure if it has glow plugs to run them for 10-15 seconds. Make sure there is fuel getting to the injectors .
      Usually smoke would indicate that you are at least getting fuel in the cylinder, black smoke usually indicates an over-fueled or under-aired condition. I would pre-heat the glowplugs for 30 seconds or so. Make sure your battery is fully charged.. Most of the time this will get it to start if there is not another problem. After trying that method a couple of times if it still won't start I would go ahead and check the air filter and then crack the injector lines at the injectors to make sure they are getting fuel.

      @@rosincore I got a question about the same issue you had here
      One of my employees laid my minix on its side and let it set thst way for 30 minutes he got it pushed back up right waited 30 minutes and tried cranking it He says it took 30 minutes of trying to start it to finally start Then he ran it pretty hard for a couple hours He never told anyone and failed to call me and report the roll over It now runs fine but puffs white smoke and it seems to have crank case pressure
      Is there anything I can do to stop the smoke Seems like it runs fine other than the white smoke and high crack case pressure

    And setting the pop off pressure?? Video is a total con, the description of a vacuum line is totally wrong. No vacuum present there, it is a leak off pipe.

      I was just showing removal and re installation. Not modifying pop pressure. That would be a whole different video explaining shims and pressures. Yes I know I mis spoke. You are correct with the pipe. Sorry I made a mistake.
