Need Help with parts

[flsmith1867]

I have a 1989 WFE Field Boss 16 with an Iseki TX2160 diesel engine. I'm not sure what the problem is. It started dumping fuel in the oil. I pulled the injectors out and #1 was wet. I pulled the air intake off and it had oil/fuel mix in it at the #1 cyl. I can drain the oil and replace the filter and run it about 20 minutes and it starts smoking black and running rough. When I shut it off and pull the oil stick it shoots out a huge spout of oil/fuel. I wanted to replace the #1 injector and need a new air intake gasket and also thought about replacing the gasket on the oil filter housing where it connects to the injector pump. Not sure this is going to fix my problem, but the BIG problem is I can't find parts. Any ideas or suggestions?

Is the injection pump engine driven? It could have a bad seal on the drive shaft of the injection pump.

I'm really not sure. I think it's made to the block and the pump itself with the nozzles come out. I don't know much about these tractors.

Its unusual for the inj. pump to dump that much fuel..
& if the injector was the problem, it would black smoke & skip on start-up.. you wouldn't get 20 minutes of run time on it..
Are you sure its FUEL?? maybe hydro fluid.. it has a small pump w/ 4 hold down bolts that has a seal around the drive..

 

[flsmith1867]

You have a good point with the hydro fluid. I did notice that it really doesn't smell like diesel fuel. I also lost a lot of diesel fuel and hydro fluid at the same time. I had to add about 1 gallon of hydro fluid because it was low and I had just filled the tank with fuel before hand and it was about 1/2 tank when this happened. Like I said in about 15-20 minutes. Where is this seal your talking about located and where can I buy one?

Upon further inspection, that "seal" in the bottom of the hydro pump looks more like a bearing.??
Just google tx2160 hydro pump to have a look..
You could remove it & put air pressure to 1 side & see if it leaks..
Same goes for the inj. pump..
Does this unit have a mechanical or electrical lift pump on it??
if its mechanical, its possible THAT has a bad seal/diaphragm & dumping fuel.??
If you don't know the answer to any of these questions or have the knowledge & experience to check the components, you need to stop & call a mechanic..

It is a mechanical injection pump. From what I can tell it does not have an actual fuel pump like on an old car or truck. It is diesel and has a mechanical injection pump. I'm having a problem understanding how hydro fluid could be getting into the engine. Where is the connection for that to be possible? I could understand diesel fuel since the oil filter housing and the injection pump appear to be one unit with a gasket in between them. And I still have no clue where to buy gaskets or anything other than a stupid water pump or alternator that I don't need. That seems to be all anyone has for sell for this this thing. Maybe I should just sell this POS and buy a real tractor. Everytime I get one thing working something else goes wrong. It has decals for WFE (White Farm Equipment) Field Boss 16 but has an Iseki TX 2160 engine. Everytime I put anything in the search bar for the motor it brings up Iseki tractors. Are they the same thing? I figure as long as the engines are the same then I don't care what brand it is.

The hydraulic pump is driven from the front timing case, it could leak from the drive into the timing case then into the sump,

 

[flsmith1867]

Would you by chance have a picture of what your referring to? I do not see a gear that drives any hydraulic pump in the timing case. I see the gears that drive the cam, the crank, the fuel injection pump/oil pump also, and another gear that drives the oil pump and an idler gear. This doesn't make any since to me seeing how the oil pump is on the other side of the motor and tied into the fuel injection pump. On the back end of the motor it has seals for the cam and a cover gasket and cover, after that you have a flywheel. At no point anywhere on this tractor can I see where hydraulic fluid from the rear of the tractor can mix with oil. I'm lost on this one. If I unbolt the trans and the flywheel the tractor would fall apart. There is nothing other than a couple of hoses and linkage rods that tie the 2 together. I have a picture of the gears that may help me understand what your talking about.

The 2 pipes from under the seat run to the pump attached to the timing case, one large one small,

See on the left (engine is upside down here) side of the engine you can see the top of the hydraulic pump with the gear through the timing case,

Gear 1 on your drawing is part of the hydraulic pump.

Have a look through my album, I have had my engine down to component level with pictures along the way.

Is your engine 2 or 3 cylinder, that drawing is for 2 cylinder mine is 3 K3B engine.

How do you think the hydraulics make pressure??
They have a pump.. a pump has to be "driven"..{turned}
Now how & where its "driven" from, is a topic for another thread..
Its awful hard to determine what type of fluid it mixing into your oil.. from here anyway.. We're just giving you suggestions.
If you feel like its the injection pump.. pull the injection pump & injectors..
I strongly suggest you buy a service manual for your engine/tractor..

The problem w/ buying another tractor is>> they use somebody elses engine too..
Just because it says, JDeere on the side, chances are it has a Japanese/Yanmar engine.
A MFerg. use Perkins engine{England}
The only manuf. that actually MAKE their own engine is Cat.. & that's only on their BIG equipment..

chrismac2012 I found your post yesterday by mistake actually. I was wondering what engine you have. Mine is a K3B also. I found the pump on the tractor itself with the 2 lines running from it. It makes sense now. You think the seal behind the gear is leaking correct?

thepumpguysc I got you, I was just confused about where the pump was located and could not see the connection. I was being stupid. I do have a service manual, a parts manual, and an owners/operators manual. They came with the tractor. Actually that's what was confusing me. The manual makes no reference as to where the hydraulic pump even is. Anyway I understand it now and see where the pump is. It does make sense as to how it can contaminate the oil and why I had to keep adding hydro fluid everytime I used the tractor. Now where do I find the parts to fix it.
