  • axle shaft bearing collar 9N-4132
  • My tractor needs axle seals. So I decide to take it all apart and put in new rear axle bearings and seals. I do my research. I drill and chisel the old collars off. I make a puller with some 5/8 all-thread and a draw-bar and pull the bearings. Drive out the old races and seals. Clean everything up. Buy all the parts. Start putting everything back together reverse of the disassembly. Just to find out the new collars don't fit. They have about .004 clearance. No press at all! And the funny thing is the bearings press just fine. So I know the axles are the right size. They measure 2.000-2.001 inches. The hole in the collar measures 2.005 inches. Anybody else experience this or ideas?

  • What, only missed by a few thousandths! That's pretty close for parts from the land of almost fits. I had a similar problem once upon a time, and solved it by taking a sharp cold chisel and "dinking" around the edge. Each impact groove displaces material to either side, increasing the overall diameter. A more professional method to do that would be to knurl the OD of the collars. That is a lot of effort/expense to make parts fit that should have been machined right to begin with. If we return more defective parts, maybe the quality will improve? Guess I can dream about new parts that fit right.

  • Old parts are being returned. New parts ordered from Just8ns. The gentlemen on the phone assured me the theirs fit. Just wait a week or two to get my return money and three or four days for the new parts. O'h the fun of working on old tractors. Mine is a 1939 9N serial number 9N4670.

  • I could imagine you having to go to a machine shop if you canít find the correct size collars.

  • Thanks for the idea. Cost would be a concern.
    I intended to rant a little in my original post about these parts companies selling these parts that they list by part number as a replacement, and them you find out like I did that they don't fit. This time I am talking about Agricultural & Industrial Products.

  • That is a simple metal ring with a 2" ID and maybe 2.5" OD x .5 OAL - shouldn't take more than 15 minutes to make. At $100/hour that is a $25 job.

    TOH
