It is about 1" from the needle bearing.I hope this helps Case Nutty. I have worked on many 580 C thru k over the past number of years, But I,m not sure about this little hole it makes no sense because oil will come out when pressure is applied. Thank you very much for any help. Thank you, Marlin [Reply]   [No Email]

I run into this a lot I will let you know what I find cnt   [Reply]  [No Email]

This hole is about the size of a ball point pen tip and located about 1" from the needle bearing in the end of shaft.Yes,it has been worked on before by someone that patch it. This guy bought it at a sale CHEAP and it has not worked right since. I think he bought it not knowing what to look for. I have worked on 580ck & B models in the past. But I do not remember of tiny hole on that inter tube in the shaft. Because if it was in forward gear for even 10 min. it would fill the shaft with oil & some pressure. I’m having low pressure in forward   [Reply]  [No Email]
