    1026R Starting slow now

    I have had my 1026R since new and it always started within a couple of rolls of the crankshaft until recently. I just rolled over the 200 hour mark and just replaced the battery. The fuel filters were replaced at the 169-170 hour mark. I have just recently noticed that I now have to crank the engine over for 10-15 seconds before it starts and it smokes some where it never did in the past. If I run it for a while and then shut it off and restart there is no problem. Let it set for an hour or so and the slow start is back. Any suggestions on what might be causing this issue? I am thinking the injection pump is somehow losing its fuel and has to crank for a while before the fuel is there to be injected but why now? Thanks, Ed

    I assume you are allowing the glow plugs to cycle, correct???

    It sounds like the glow plugs are not working, or you are not allowing them to cycle, since not getting fuel will not cause it to smoke when it finally does start.

    Yes, I am following the Glow Plug Cycle, I have owned this tractor since March 2013 and it was new with less than an hour on the clock. I have not had this issue until recently so something has changed. During the summer even if I didn't follow the glow plug cycle it always fired in a couple of cranks, just smoked, now I have to crank it for 10-15 seconds before it fires. I am worried more about this winter when the snow is flying and it is below zero here in Michigan and it not starting when I need to blow snow.

    This sounds fuel related to me, like you have an air leak. Have you let the fuel pump prime for a few prior to attempting to start? Try this the next time it *should* be slow starting again and see if that makes a difference. If it does, change the filters again and pay attention to seals and hose ends looking for leaks.

    Note, you can have an air leak but not have fuel leak. I know that sounds strange, but it happens all the time with diesels.

    Make sure your electric pump is even working. You can pull the line off the filter and turn the key on. Observe the flow. It should be pretty good, not a trickle.

    I also think you're losing your fuel prime, check all over for any loose fittings or signs of fuel seepage.

    Do you use any diesel fuel additives? Have you recently changed sources for your fuel? Just brainstorming.

    Beautiful beaches, moderated summer heat and lake effect snows. Right where I want to be.

    I don't think this new starting problem and the very recent tractor service are a coincidence. The advice given is spot on. I would be looking for an air leak or perhaps the fuel pump has stopped working. Fuel pumps tend to either work or not work but an air leak in the system adds complicating consequences.

    One of the things I have noticed is when the fuel pump isn't working the tractor starts hard, will lose power going up hills and it will run just fine headed down hill or on level ground, once you get it running. But it did run with the pump not functioning.

    Any chance you put the small fuel filter in backwards or that you have the fuel filter in the separator not installed fully in the up position, affecting the fuel flow after the engine has been sitting?

    What about a fuel line being pinched as a result of the service? The little under the floor board filter is a challenge to change and it helps to loosen the clamp on the fuel line. Maybe the clamp got turned and is partially pinching the line or maybe even this area is a source of your air leak......

    Does the glow plug dash light seem to be staying on as before and going off after the normal amount of time?

    Cranking for 10 to 15 seconds is quite a bit of time, really. Be careful about keeping the starter engaged too long when you are having trouble with the starting.

    I am sure you will, but please make sure to let us know what you find is the culprit so others can learn from your experience. Hope you find the resolution an easy one. You are going to need it for snow duties pretty soon.......

    Sundancer, do you hear the electric fuel pump run when you turn the key to “on”?

    It’s been observed before where the wire has been pulled out of the pump, or I believe they can just go bad.

I checked the Fuel Pump yesterday, I placed my hand on it and turned the Key on and felt it running. If this continues, I will do a flow test when I remove the FEL and install the Snow Blower.

    Any chance you put the small fuel filter in backwards or that you have the fuel filter in the separator not installed fully in the up position, affecting the fuel flow after the engine has been sitting? No, I have been a mechanic since the mid 60s and I am very careful on that aspect.

Maybe the clamp got turned and is partially pinching the line or maybe even this area is a source of your air leak...... An air leak might be a possibility and I will have to check it during the change over.

    Does the glow plug dash light seem to be staying on as before and going off after the normal amount of time? Glow plug light has not changed and acts normal.

    Cranking for 10 to 15 seconds is quite a bit of time, really. Be careful about keeping the starter engaged too long when you are having trouble with the starting. I am very careful about overheating the starter, I did that once when I was a kid and it was a very miserable experiance changing out laying on the ground with minimal access.

    I am sure you will, but please make sure to let us know what you find is the culprit so others can learn from your experience. Hope you find the resolution an easy one. You are going to need it for snow duties pretty soon.......

    I placed my hand on the pump and turned the key on and felt the pump running yesterday. I then started the tractor after a minute or so and it started right up as in the olden days. I just might have to wait a lot longer to start, though I still don't know what might have changed. This issue did not start immediately after the filter change out but several months later. The filters were changed last fall and I went through the winter with no issues until late this summer when it started acting up.
