Hi everyone. I have a 48 8n with leaking rear axle seals. After taking it apart I noticed the axle threads were stripped, not terrible but enough that the nut cannot be completely tightened. The PO must have ran it loose for some time,also the hub was worn so I bought a new one from this site. I took the axle to my local machine/welding shop to have him fix the threads. He tried many sizes of taps? I'm not sure what the name of the tool is to cut/repair threads. Anyway, he couldn't figure what size it took. He said they were finer than fine threads and a metric size was close but not perfect. I doubt the threads are metric. Anyone been here before? I Appreciate all Help! Thanks BJ
