Thermostart cup replacement

[pennwalk]

I'm working on a YM180 that I bought for parts but I started to wonder if could get it running. The thermostart cup is missing and been replaced with a generic fuel filter. does anyone have an idea for something to replace it with? The fuel filter would have been ideal if it had 3 inlets.

Someone put a fuel filter where the thermostart is???? You definetly need filtration but you can start it without the thermostart unless its REALLY cold. Since you have a domestic model you should be able to find the thermostart parts at the nearest yanmar dealer - maybe - but your are probably better off calling Jamieson Tractors or Hoye.

Hoye sells a kit : http://www.hoyetractor.com/mm5/merc...e_Code=HTE&Product_Code=TS-KIT&Category_Code=

You should just need the factory bottle if everything else is there--

Yanmar Tractor Parts: HEADER TANK

There is no need for a filter between the injector return and the fuel tank.

I interpreted what pennwalk said to mean somebody had used the fuel filter as a reservoir for the Thermostart, since it has a built-in inlet and outlet, is designed for fuel, etc. That's actually a fairly clever idea; I have seen some filters with 3 ports.

The correct part from Hoye is cheap and easy, though, and will mount to all the brackets correctly. I don't think it takes very much fuel to make the Thermostart operate. Probably the fuel in the lines would be enough for it to fire off if functional. You could try it as-is and see how it goes. If the injection pump moves fuel to the lines and there is compression, it will probably run.

The previous owner used the fuel filter to connect the return line from the injectors to the line to the fuel tank and the thermostart line is hanging free. That is the king of stuff I am correcting. What I was looking for is a cheap temporary homemade idea until I can decide if it is parts.

I don't have the mounting bracket either or the cup and very Rarely ever use it here in Ga. My TS.Igniter worked after running a test lead to it and then I wired it to the Ign. switch and this is all I used. It's off an old Antifreeze tester and a old fuel line. What really works good and to fill it just give it a squeeze and stick it in the the Fuel Can or Tank. I leave it off most of the time.

Back in the carburetor days most cars had some sort of return and a lot of cars used a 3 line filter to accomplish that. AMC for one I can think of right off in late 70's ish the return line would be the one you want to go to the TS unit.

fwtw if you dont want to wait on Hoye and UPS the AMC filters are 5/16 though with a 1/4 return (I have one hanging on my filter peg board still) and probably cost a few bucks at the zone. May need some line stretching or find another one with smaller ports on all.

You might want to go to a John Deere dealer and buy one for a 950 tractor insted of the Yanmar part. It is the same size and shape as the Yanmar part and fits the same bracket, but has no cap and fills from the injector return line. Never have to fill the bottle, always full. Line in from the injector return, line out, to the fuel tank return line. I did this years ago and it works great, never a issue. Good luck,

That's interesting. The JD dealer is nearby and I have been thinking about how much it costs to drive across town what with the high cost of gas. Thanks

That sounds like a great idea.:thumbsup: I get tired of removing the loader bracket just to check my bottle to see if there's any fuel in it

I'll be surprised if John Deere sells theirs for the $13.96 that Hoyes lists theirs for. Of course you have shipping verses taxes verses gasoline to pick up, but then again taxes may not apply if farm equipment.

I can't remember what I paid for mine, made the change over years ago. I also own a John Deere 950, and when the little bottle cracked on my Yanmar 3000, I made the change to the JD setup. Cold winters in NV and the thermostart gets used for every start in the winter. I got tired of filling the bottle after finding out with the JD you didn't have to, it was always full. Could the JD cost a few bucks more, think so, but worth it. Hoye tractor might even have the other bottle without the cap in stock if you ask ???

The one Aaron attached in his post is the one without the cap. $13.96

Not trying to down sell Hoye at all but for temporary purposes the FF with return will work a lot cheaper here is a pic in case it isn't clear what I am talking about Chris. hth

Not sure what it fits the box wasn't with it but Dodge v8 2 bbl carb mid-late 70's comes to mind??? Its 5/16 and 1/4 for the return. My guess is it would be a few bucks at the zone etc and its only 2" long. fwtw

 

[TGeorge]

Personally, I would buy the thermostart cup from Hoye that is designed for a Yanmar tractor.

thanks chriswheeler for the jd950 tip I picked up a used one at Wengers of Myerstown PA for 9$.

I didn't have much to do yesterday. So, I went to the auto parts & found a fuel filter similar to the 1 you posted & replaced my old thermostrat cup

Should have mentioned that the JD 950 is a yanmar made product at the start, made in japan on yanmar's production lines. Many of the parts in my YM3000 interchange with the JD 950, this little thermostart bottle is another one of them. JD just wanted one that self fills. Fits the yanmar bracket perfectly because the JD 950 is a yanmar. Same JD thermostart bottle will fit most of the YM series tractors. My second choice would be to go with Car Doc's setup, his would do the same thing, just not fit the bracket the same way. As a side note here, no, not all of the parts interchange, JD had some different specs used in their tractors. 70% interchange possible. Their 750,850,950 and 1050 all have the same story. My YM 3000 was the closest tractor made to the JD 950, still major differences, one big one is the engine. YM 3000=3T84, JD 950=3T90J, many others.

For $14 plus shipping I would buy the one from Hoye and not have to getto rig something that you might have to replace in the future. Good luck!!
