F-220

nocny drwal · Dec 4, 2010

Indeed there are no spark plugs. So this light indicator is for glow plug?
Today was -20 celcius. The battery was fully charged overnight in a warm place. Unfortunately tractor didn't start. After that I conected battery with another battery in a car. This time my yanmar started. Maybe it is a worn-out battery problem? Or maybe it is not sufficient for this type of tractor? its: 12v 74ah 680 en.
thermostart ? Actually I haven't found it. Maybe You could help me with this fotos? This thing that I have marked with red circle; could it be a plug?
Thank you for respond

Also Ducato is refusing to start

Noncy, I don't think that is your thermostart unit, I think that may be the temperature sending unit. In this same forum look at the post entitled "thermostart vs magnetic oil pan heater. There are pictures there of a thermostart unit and components. I do not see a little plastic bottle that would be your reservoir for the thermostart. Does your ignition key have "TS" on one side of it? Another thing to consider is your compression release. I do not see one and don't know about the F220. I see holes in the side of the rocker arm cover in picture #3 about where the compression release shafts would go thru but really don't know whether yours ever had it or not. I'll conclude by saying these little diesels like fast rpms while cranking.

There is no plastic bottle. I have read this thermostart vs magnetic oil pan heater. It seems that the f series don't have thermostart

Also I have checked if these magnetic oil pan heaters are available here in Poland. Of course they aren't

Another thing is the compression release. I had had yanmar f 155 before the f220. The f155 had got compression release. The f220 hasn't got it.

Tomorrow I'm going to check if this thing I have marked is really a plug (glow plug?)
There is one more question. It's about that glow plug light indicator. When the weather is warm, this indicator turns off quickly. Right now it takes about 15 seconds to preheat. After about 5 times I do repeat the preheating process it should turn off faster, should it not?
After I managed to start the tractor and make the engine warm, the glow plug light turned off almost instantly during next cranking. So I assume the tractor read the temperature correctly but I'm not sure if the plug itself works correctly.

I'm going to try to replace the plug. If this wont help I'll try to change the battery.

Nocny, you should not have thermostart but MAY have glow plugs. Some models, I THINK, had glow plugs as options at purchase and therefore not all came with them. MY FX24D was a hard starter in the winter with glow plugs. I used the largest/strongest battery I could fit in the battery box for extended cranking needed in winter. Looks like you have a solution with the dual battery approach. High revs and patience.

You might go and check the glow plugs and their electrical circuit. If they are bad glow plugs are standard and readily available.

Nocny, this may be what you have. Yanmar Tractor Parts: GLOW PLUG FOR F SERIES_

I'm still not able to find that glow plug on my tractor. Is it possible that it is really an option? But I suppose if it was an option there wouldn't be this light indicator. In my case there is that light so I think there should be also a glow plug somewhere.
That thing which I marked is not a glow plug. Today I managed to take it out and thats what it looks like:

When I had removed it, a coolant liquid started to leak.
Also I have found this:

It looks like heating system for an air. It is connected to the air pipe from an air filter. I didn't check if it works correctly. I'll do this tomorrow.
So could anyone tell me where that glow plug should be? In which part of an engine should I look for it?

Nocny, that is a picture of your temperature sending unit. Nothing to do with heating fuel. Your second picture of the finned looking apparatus. Is there electrical going to that someplace? Sure looks like a heat exchanger. Glow plugs should be in the area of the injectors and I see none on yours. Not familiar with your model so maybe they are hid but I doubt it. Is that light on your dash labeled? Perhaps it is indicating the heat exchanger is working? Very very interesting.:licking:

I would think this is another version of a glow plug. Looks like it is heating up to warm the air going into the intake. I am assuming the rubber boot on the right side of the photo has electrical wires in it.

i would say thats it also, my toyota landcruiser has that style of heating element in the intake manifold instead of glowplugs. it runs for about 30 seconds after the vehicle is started then turns off, you notice the volt meter rise when it turns off.
