Yanmar 2000BD Not started for 2 years

[bookman51]

I tried to start the tractor this evening. Battery charged up fine and engine turns over fine. But no start. Checked fuel. It is,getting to the filter but not out if the filter. Took fuel line off going into filter and fuel came out. Made sure fuel valve on and tried to bleed it. Nothing. Took fuel line off going out of the filter with valve on. Nothing. Tomorrow i am going to get a new filter. If it were one of my 40s and 50s farmalls i would say screen at top of sediment bulb plugged with crud. Dont know about this tractor but i hope to find out tomorrow.

IIf it were one of my 40s and 50s farmalls i would say screen at top of sediment bulb plugged with crud.

The outer side of the paper filter serves the function equivalent to that Farmall screen.

Tomorrow while you have the filter bowl off, turn the shutoff back on and verify that fuel is arriving at the (missing) filter bowl.

Then keep in mind the recommended bleed sequence to refill the bowl and the line beyond the bowl:

1) bleeder screw by the shutoff. (bowl input) Bleed until no bubbles.

2) screw to the right of that. After the bowl fills, fuel should come out that bleeder without bubbles.

3) bleed the screw down on the pump inlet fitting.

Observing fuel at those three bleeders, there is no need to disconnect fuel lines.

And the common wisdom is that there is never a need to open the high pressure lines beyond the fuel pump. The pump will eventually push any air out through the injectors so don't introduce more!

I would bet that rather than a totally blocked filter element, you have air somewhere before the fuel pump.

Thanks but if the fuel filter not blocking it would i not have fuel flowing out when i take the line going out of the filter off and turn the fuel on? I guess i will find out later this morning. Thanks again.

Any news?


Guys I think he got it running and is out joyriding, having too much fun to come indoors and post.

if you follow the bleed procedure esp after you put a new filter in I but this thing roars to life.

Sorry, but it has been raining here and I ran into other things I needed to do first. I plant to get back to the tractor late this afternoon and will give a report when I do. Thanks for all the good advice.

I worked on the tractor late this afternoon. The fuel on and off switch was not seated properly. I got it reseated and got the fuel turned on. I bled the lines at the proper places but then it looks like there is a leak in the fuel line between the fuel filter and the injector pump I got the tractor started but it only ran for a few seconds and died. I assume maybe air was getting into the fuel line. So, tomorrow I am replacing the fuel line. In addition, the battery did not stay up long. So, putting in a new battery tomorrow. Good news that the tractor runs; bad news is that it will not run long.

Since you decided not to drain the fuel at least use a glass jar or glass cup to check it for water before you start letting a bunch of it run through the engine. It will let you know whether or not the fuel could be causing rough idle if you experience that once it is running. The best time to sample it is while you have a fuel line loose or changing the fuel filter so you don't have to take one off again later. Glad you got it to run for a bit...that is a good sign.

...use a glass jar or glass cup to check it for water...

These have a semi-transparent filter bowl where water will be evident, and I think he said he had that filter bowl off to diagnose why fuel wasn't arriving to the bowl. As you noted, it still would be a good idea to dump the filter bowl into a small jar to better see any water.

Here's a photo I posted long ago showing the Yanmar filter bowl, the new one in the photo. Installing the proper fuel filter assembly was one of the minor things I needed to remedy when I bought a sound but neglected YM240 in 2003. It had an aftermarket fuel filter, so I went to a gray-market importer and bought an OEM Yanmar filter assembly that I watched them take off a (VN) 'Factory Reconditioned' warranty return tractor.

As shown in the photo, the 'Factory Reconditioned' bowl and element were clearly salvaged from something unrelated! That stubby filter element and bowl were never used by Yanmar. I then bought the proper element and bowl from Hoye.

Yanmar had a shorter filter element but not as short as this mystery element in the photo. This one doesn't even touch the bottom of the bowl to hold it snug against the outlet pipe it slips onto. The photo is an illustration how the VN 'Factory Reconditioned' Yanmars may have been built from mismatched parts.

Bookman51 we're all rooting for you! I think you'll love it when you get the minor bugs out of it.

I figured it would be easier for him to see it in the jar because who knows how dirty or discolored his fuel bowl might be and I didn't recall if the 2000BD has a water indicator ring in the bowl like some other tractors do. You know how it is...kind of hard making suggestions without seeing photos of the tractor he is working on. I'm certainly not that knowledgeable about the specifics on the Yanmar like you are. I am just super eager for him to get it running successfully. I'm probably being a little overkill on the fuel thing but I encounter so many tanks with water in them, stale fuel, or gummed up fuel lines that I just default to draining the tank to start fresh on items that sit 2+ years. Well, that is on anything that has less than a 10 gallon tank. I'm not about to drain a 55 gallon boat tank without testing the fuel first....lol. OKAY OKAY...I'll shut up about fuel now and will stop bringing it up. :laughing:

I'm hoping after he replaces the line that she fires right up and there will be no need for anything else but I'm here to offer suggestions in case she doesn't. Feel free to correct me if I suggest something stupid or say something wrong. I know enough to know there is always someone out there that knows more than me and can teach me something new.
