  1. turbocharging

    turbocharging

    I put a turbo off a wreaked skid loader on my 4341 with good results. I think total volume of air needed is related to horsepower desired. The problem with most car type turbos is that they are so concerned with response that they have smaller turbine sections (high rpm and back pressure) than...

    wiring diagram for 4340

    My neighbor has an older 4340 that is having some electrical issues. Where could we get a wiring diagram for this? Also, it has the old style fuses. Does anybody know of a good sorce for these in the US or should we pull out the fuse block and replace it with a modern style? Thanks for your...

    HELP... smoke comming out of crankcase breather

    Thanks for the help guys. It's back together and seems fine.:) I'll run it through a few more heat cycles then retorqe the heads and recheck the valve clearances. I'll get some fresh fuel from a different supplier before I really make her snort. I will let you know if there are any other...

    HELP... smoke comming out of crankcase breather

    Thanks for the input guys, The tractor works good enough with the snow thrower that I have decided messing around with the turbo isn't worth the $ and effort. I also now have some concerns about reliability and don't want to cause myself needless irritation. I checked the injectors and they...

    HELP... smoke comming out of crankcase breather

    Thanks Mike and Dave for the input. When I removed the liner there was some stuff that looked like flocking or an old deteriated (sp?) cotton ball between the cyl. and the water jacket. It was on the other side of the cyl from the scoring. I cleaned it out and will flush the cooling system...
  6. HELP... smoke comming out of crankcase breather

    HELP... smoke comming out of crankcase breather

    Another update, 3 good cyls and one scored. Pulled the piston and liner, top 2 rings welded to piston. I guess I have to chalk this up to operator error{:-(. I should have known better that to lug it that long. New parts should get here next week. It will go back together quicker than it...
  7. HELP... smoke comming out of crankcase breather

    HELP... smoke comming out of crankcase breather

    Thanks Mike, Just in for lunch. It already has the 1.2mm head gaskets, so I guess cleaning up the ports is all I can do to improve power. Above the stopping point for the top ring it was smooth enough that I couldn't feel a step with my fingernail, (after I cleaned off the carbon) and the...

    HELP... smoke comming out of crankcase breather

    Hi Mike, No previous sign of distress. Water temperature at incident was not quite touching the begining of the red (I have an addenum to the manual that says due to calibration the normal range includes the first couple of red marks). This is where it has run under load since new. Oil was in...

    HELP... smoke comming out of crankcase breather

    Thanks for the input guys, I have the heads off. Nothing looks obviously bad. The number 3 cyl. looks "cleaner" than the other 3. There is a possible crack on the top of the piston but I didn't dare scratch at it with any hard, in case it wasn't. Tomorrow I will clean it up with rags and...

    3045 now running! more advice needed please

    If a head is not flat, how much material can be safely milled off before concern about piston to head/valves becomes an issue? Daryl in WY

    HELP... smoke comming out of crankcase breather

    Thanks Dave, That's what it sounds like to me. I'll go out and pull the heads off now. I hope I don't have to change the sleeve. Should know in a few hours. Should these things have an ignition "rattle" after they are warmed up? Could this have been caused by the fuel injection having too...

    HELP... smoke comming out of crankcase breather

    Hi Guys, My 4341 moved a lot of snow this winter. Good so far. Today I was grading with a double blade grader. I was coming uphill in 3H and the fuel control unit was wide open for 4 to 5 min. with the RPM vareing between 1500 (rarely usually it was above 1700) and 2100. It pulled down to...

    7745 with noisy transmission

    imho the air tank would not be worth the bother. The block heater is not absolutely nessesary, but I believe very worthwhile. I live in WY and it is much easier on the starter when it has been plugged in for 30 to 45 min. My tractor is stored in an unheated shop and the smoke from starting...

    turbo for a 4341

    Thanks Rense, I should be able to find one of those. It will be a while before I get to it but I will keep you informed. I have a couple of pictures but I can't figure out how to attach them. If I email them to you can you attach them? Daryl in WY

    turbo for a 4341

    I raised this issue awhile back but would like to revisit it. I live at 8750 feet elevation and have to deal with a bit of snow. I bought a wrecked 8 foot three point snow thrower and spent last summer rebuilding it. New: cutter bar, main shaft, all bearings, all seals, 25% of the sheet...

    6441 smoky startup/ 4341 increase compression?

    Hi guys, I havn't been on for a while as my 4341 has been trouble free :). My neibor bought a nearly new 6441. It is very nice. One issue: it smokes on start up untill it is warmed up. Even warm it smells more of unburned fuel than mine or another neibors older turbo zetor (i think it is a...

    Tractor choice-NOT EASY

    If you are in the USA, the resale value falls sharply on the Zetor. If you buy a used Deere, Kubota, Case or that blue tractor for the same cost and have to sell it in a couple of years, your cost of ownership will be much lower than buying a new Zetor. (Assuming you don't get unlucky with...

    Shuttle shift on 4341

    Hi, The shuttle is NOT syncronized on the 4341. Only the top 4 gears in the main are. I bought mine before I noticed this. You just have to come to a complete stop before moving the lever and then go straight through to the other direction. It took me a while to get used to this as old...

    How too adjust Diesel pump at Zetor 5011- Year 82

    TomZ, Thanks for your insight. That is what I thought would be the case. The turbo conversion (or any other upgrade) is on hold for a while. My daughter is getting married just after Christmas, and we are dealing with that now. My wife and I went out into the woods with a preacher and our...

    How too adjust Diesel pump at Zetor 5011- Year 82

    Hi Guys, gotta love that green Zetor. I grew up on a farm using 2 cylinder John Deeres. I wanted one when I was shopping for tractors this time but they are just too pricey. Is it possible to increase fuel flow on a 4341? Is it desireable at 8700 feet elevation? Daryl in Wy.

    Anyone else blow snow?

    Depending on how good the seals are (or are'nt) you might consider waterproof grease. I agree that every 8 hours of actual use should be fine. By the way, have you guys heard of the "Fair" snow thrower? It is made in South Dakota USA where the winters are rather fierce. Lots of wind and...
  24. Turbo addition to 4341?

    Turbo addition to 4341?

    Thanks for the replies. Intake tract icing under light loads hadn't occured to me. I had an early Subaru that drew intake air over the exahaust manifold like an airplane to prevent carbarator iceing. I have never heard of this being a problem with fuel injected engines. Is this common with...

    hello New member with Zetor 5011

    Welcome Smelly, There are few of us in North America. The guys in Europe have a lot more experience with these things. The good thing is that they are pretty basic and seem to last with few serious problems. Daryl in Wy.

    on the 4341 engine oil filter there is a Ford truck filter that will work. When I am at the shop tomorrow I'll try to rember to write it down the number and post it. I haven't found any substitute for the hyd./transmission or power steering filters. The power steering filters aren't very...
  28. Front blade

    Front blade

    Hi JP, A snow-blower on the back with a blade up front to clean up heavier snow and windrow the light stuff so you can through it down wind is, IMHO, almost the perfict set-up. I would rather have the blower on the front, blade in back, but that is a much more expensive set-up, and the front 3...
  29. Turbo addition to 4341?

    Turbo addition to 4341?

    One more question and I'll stop taking up your time for a while. How much boost does the stock turbo have at sea level? How about at 8000 feet elevation? I seems to me that if I were just getting back the power that is lost due to the thinner air, I might get by with the stock valves and...

    fuel problems on a 4340

    If the copper washers are hard to get it may be possible to anneale (sp?) the old ones. Piston airplane engines use copper washers on the spark plugs and they are removed and cleaned/inspected every hundred hours. Every second time we reuse them we just heat them slowly with a torch until they...
