Thanks, I would love to know!I “fixed” mine but I found a very inexpensive New Old Stock steering valve on Ebay. I saved my old box but have not torn it apart.
Best regards,
Jim BRe cold weather operation.
My 1979 Peugeot Diesel Owners manual recommended adding “Up to 10%” gasoline to the tank to improve cold weather fuel flow. It had a CAV rotary pump, I did put over 200K on it before I sold it and never had problems with the pump or injectors. Ran out of fuel once and mixed 50% bar oil and 50% saw gas and made it the 20 miles to the fuel station lots faster than walking. I would not recommend either of these things but those old rotary pumps were pretty robust.

Hans,
Since all of most of my tools including my brain think in English units I created a list of some of the engine specs in excel. I did spring for a few of the manuals and I am happy to have them but i do not mind sharing the info. Please use with care as these have not been vetted by anyone.

I do not personally know anything about them but I did find this thread.

Looks like a Lenar dealer may be able to help you.
Hope that this helps!

Hello,
I hope that you have your tractor fixed but if not I would suggest that you jack it up, block it well and pull the front drive axle out and take it apart. It is a very simple device and it will be easy to figure the problem out once it is dissembled. When i picked up my 354 last year it had no Front drive. I suspected that it would be a spider gear in the front dif. What it turned out to be was the left drive axle snapped off at the area between the shaft and splines. The cause of the failure was that the PO had failed to keep the studs holding the axle tube to the center differential properly tightened this caused a misalignment putting the axle under stress.
My 354 has a FRL and I suspect it was worked pretty hard. This probably caused the axle housing studs to work loose.
Good Luck,
Jim B
Jon,
Looks kike the link did not work.
My thread is in tractor troubleshooting (this one) and is titled
“TY395E no Throttle Response when cold”
jim
Jon,
Your symptoms sound very similar to mine. Very poor low end power/throttle response but pretty much fine above 1400-1600 rpm.
Check out this post:

Mine was a bit worse cold. It would start right up but if you tried to throttle up it would smoke like mad then possibly stall. If you slowly ramped up the speed it would then run fine.
No governor response at all at low speeds . After the adjustment it just runs super, you can drop it back to 800 rpm and ease the clutch out in 2nd and high range and take right off. Before now way at all that it would do that.
Hope that your problem is related to this.
Jim
Jonn,
This sounds much like the symptoms that my TY395 E was exhibiting.
No power at low rpm.
Do you have an EPA engine? I found a that a problem with the thermally regulated fuel limiter (on the inj pump) .was causing my was causing the problem. A minor adjustment solved it.
Jim
Bob,
Good to hear that my problem is not unique.
Your advice on monitoring oil pressure is good.
I kept a close eye on the oil pressure when I was evaluating the fix and all was well, I should probably add an audible warning for low oil pressure and high engine temp. When I am operating the machine under extreme conditions my attention may be on things other than the gauges.

David,
It is not intuitive to me that the oil would build up to a level that would cause this issue either. My engine is “immaculate” on the inside as I just completed an in frame refurb only 30 hours ago so it is not an issue caused by sludge etc. It has no noticeable blow-by with the new sleeves pistons and rings.
It had the problem before the refurb as well so it is unrelated to me having the engine apart. My place is very hilly and I may possibly operate my tractor under unusual conditions. It take a while for the symptom to appear when you get it into the situation that will cause the smoking, it recovers very quickly as you get near level.
I did not examine the oil return system in detail but the push rods are on the right side of the cylinder head so that probably explains why it is aggravated by being biased to the left. What is probably happening is that the oil builds up in the front corner if the valve cover and the valve spring splashes the oil enough that a significant quantity makes it into the breather hose.
It would be interesting to see if it is only the TY395E engine that has this breather design. I have no idea how many tractors were built with this engine.
Have a great day,
Jim
