  • 8N Rear Axle Gaskets, Shims and Seals
  • With wheels, drums and hubs removed from my 8N's rear axle I cleaned all parts today. In the process I found some anomalies and want to ask for advice. Part numbers referenced here come from Fig. 34, P. 40 (Sec. 151) of my Service Manual 1948-1952 Ford Tractor Model 8N.

    There were more than two paper gaskets (4130) per side, as if they had been used for shims. Is this acceptable practice? There were steel shims (4229) on both the left and right axle assembly; 3 left, 2 right. Is this recommended practice? Next to the bearing there was a small fiber seal. This is not indicated in my manual. The manual does indicate a seal (4294) behind the axle nut (4179) and flat washer (4293). This seal was not in place on either side.

    On the right side one of the two metal shims (4229) was broken at a bolt hole. Just8Ns, Steiner Tractor and Yesterday's Tractor do not list either the 4294 seal or the 4229 shim in any dimension.

    Does anyone know of a source for these items?

  • FWIW: I managed to make out the serial number: 8N184383. This puts the tractor in 1949 production. I had thought it was a 1948.

  • Serial Number means very little. Unless you have an early model you plan on restoring to all original, N's are basically the same. The 9N/2N are the same after s/n 12500, and early 8N all used the front mount distributor. 8N added POSITION CONTROL, new generator and Voltage Regulator, new starter motor w/Solenoid, new wheels, new air cleaner, and new steering to name a few. Some N's, when engines were blown, were then replaced with used engines from other models so many 'mutts' exist out there. It is possible to have a 9N/2N with an 8N motor and vice versa. I advise to get the TISCO complete Carb Kit -the best around. If you need help with your, email me, it's open.

  • Here's the LINK to YT for the steel shim replacement part. It has 12 holes and is a universal part meant for many applications. Your 8N has only 6 holes. It is .020" thick and may require multiple ones to fir right. Good luck.

  • Thank you, Tim, for the link. I ordered two steel shims and eight paper gaskets as well as two 4290 and two 4284. On my axles, just outboard of the bearing assembly, were cork rings, approximate OD 2.375 in., 0.5 in wide. I think the 4284 replace these. They are not depicted in my manual's exploded view, however.

    I also ordered a carb rebuild kit, but that's a separate discussion.

  • Paper works as a shim & probably can't find the metal shims now days.
