  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...

    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...

    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...
