I have a Nortrac 204c. It has been running like a champ until a few days ago.
While moving some dirt with the FEL, the engine started to lose power and was running rough. I had to feather the throttle to get the RPM's up enough to keep it going. Then it just stalled out completely.
I assumed that the problem was with the oil level in the Fuel Injection Pump. This has happened before and the symptoms were identical to this instance. I filled it up and then cranked the engine. It took a while but I got it started and it ran very well for about 20 minutes.
Then it did the exact same thing as before, ran very rough, then went out completely. The oil in the pump looks fine.
What else should I check before attempting to start it up again? Did I miss something? This has been a very dependable motor and other tan it being my first diesel and learning some new tricks, I haven't had any major issues.
Thanks in advance for your input.

I have a Nortrac 254 znd experienced similar problems this last year. I was mowing and it started to koose power and miss. Gradually it died. Had to get off and fiddle with the injector pump. Would start and mow again, the it would loose power and die.
Changed the fuel filter and it ran okay for awhile until I was moving snow when symptoms reocurred. Took the screens out of the fuel tank, and the sediment bowl, to reveal the problem of those fule bugs, Cleaned the screens, and the tank, and it been running like new since

Thanks for the replies. I changed the fuel filter last fall just before I put it away for the winter. It was inside during the winter and started up well once it got warm enough here. Last summer I drained the tank, cleaned all of the in-line filters and replaced the main filter.
I will pull the fuel sediment bowl off and check for water today. I have one of the plastic-style bowls that is no longer transparent as a good fuel bowl should be. I think that I will pull it off the tank and replace it with a glass filter bowl assembly so that I can check it visually in the future.
It's a rainy day here today so I can't move dirt until it dries up a bit.

Tommy,
Does your company sell just the sediment bowl alone or do I need to buy the complete assembly? The part number in your website is CO 708-1.
The part number in my parts manual that came with the tractor for the assembly is 180.50.021. Which one is correct?
The drawing of the part in the manual is so crude that I can't tell if it is correct.

Update on my problem, I pulled the Tank Sediment bowl assembly off the tank and found that it was partially plugged. Probably just enough to cut off the supply to the engine and stall it. I cleaned out the rest of the system and the engine started.
I moved a bunch of dirt and rock yesterday. Seems to be doing well.
The Sediment Bowl/Filter/shut-off assembly will have to be replaced however since the mesh filter has a tear in it. I can't imagine how it got there but no use in keeping it in the tractor.
Tommy: Both of the Bowls that you have in your inventory look just like mine as far as the location of the ports, etc. I can't see enough detail in the pictures to see the difference. I guess I don't understand the difference in the tapered vs. straight threads. Can you explain this further? Which one would be the correct part for my tractor? I took a picture of my assembly if that helps.

The New type has a Nut that tightens to the bottom of the fuel tank, the old style does not.
Send me a pic of yours and I can tell you right away

Bob:
Thanks for all the info on diesel bugs. I have never had a problem and since reading topics on this I thought I should try some preventive measures. I looked in several stores for an additive and asked some store personnel, but no one ever heard of this problem or an additive. Do you know of a brand name or type of additive I could purchase? I would like to use something so I don't come up with this problem.
Thanks again for all your assistance in dealing with problems/fixes for our equipment.

I use Hammond's BioBor JF which is available at most marine and aviation outlets.
Every six months I test my fuel with a Hum-Bug test.
I cannot overstate the damage these bugs can do to a fuel system, even dead ones.
There are lots of fine fuel biocides on the market, the problem is educating people to use them, or at least test their fuel for them. That said, if you go through a tank every week and purchase your fuel from a high volume source you are probably OK.
If not, it's cheap insurance to test it once in awhile.

I agree with Tin.
Lots of people and companies “stockpile” fuel. Nothing wrong with that at all. I do it too. What I have found to be my Achilles heel for fuel storage is the regular atmospheric vent, where fuel vapors mix freely with air so when in conditions of high humidity or cool fog the condensation just goes beserk. I remedied that situation by installing pressure/vacuum fill caps on my storage tanks. They thread into a standard 2″ NPT (drum bung) and have a removeable cap and seal not unlike a large radiator cap. Free air cannot pass. Seems to work, haven't had bugs for quite awhile now, but I still test.
