I ran it a couple months and tried everything I could think of to get it to stop without rebuilding it. It had puzzled several people as to how this tractor could run so good with that much blow by. No blue exhaust or white exhaust smoke so I tore it down and did not find anything wrong no broke or stuck rings I put new rings pistons sleeves bearings and had the heads done. I've ran it 50 or so hours and still doing the same thing does anyone know why it's doing this thanks ben [Reply]   [No Email]

It just needed seated in good. After two runs down the track blowby was gone. How has it been ran in those 50 hours? [Reply]  [No Email]

Your CASEIH dealer should have one and the orfice that is used to test the IH 400 series engines will work on that Case engine as well. If it reads less than a total of 5 or 6 inches of water I would not worry about it. If more, well, it can be caused by worn valve guides as well as leaking past the rings. I have seen some really worn guides on those engines. [Reply]  [No Email]

Yes, another bad injector will cause a skip. Did you have them all checked? Has the pump timing been checked? If I read correctly, you did replace the sleeves? Some sleeves are semi-finished & need finish honing...... [Reply]  [No Email]

I was told that the tractor had broken rings. The engine did not smoke the tractor started and ran like sewing machine and the owner said it didnt use oil. My better half heard the part about broken rings and decided i didnt need anything else to work on. Now it appears that what i thought was excessive blow-by is normal. ****** that means i may have let an decent 1175 slip through my fingers To get back to reality could it be the blower has something plugged causing what appears to by too much blow-by?

We have 12 tractors 4 around the same hp and it's torque really sets it apart I bought a new blower about 2 months ago before I tore it down their is a lil oil in the vent tube btw [Reply]  [No Email]

If the blowby is reaching the ground on a calm day. If it doesn't use oil I wouldn't worry about it. [Reply]  [No Email]

If it blows your hand away or fills with oil then there is still a problem. Did you offset all the piston ring gaps? Too big of a turbo? Thats a stumpper for sure... [Reply]  [No Email]
