  • Leaking Hub Seal
  • I hope I am not posting too many messages.

    I have noticed oil stains on the left rear wheel for some time now. I don't think it is a heavy leak. This has worried me for some time because I don't think I can handle this job due to the wheel. For one, if the wheel fell on me, I could be under it for a week before anyone would come looking to see what happened to me. I was told these wheels are heavy; there isn't any fluid in the tyre at the moment. The other thing is that I read you have to torque the nut to 400 lbs-foot. I have no way to do that. I don't have a torque wrench that goes that high. And if I did, I am not strong enough to apply that amount of force; it was all I could do to torque the crank bolt on my car when I had to replace a bad sensor behind the harmonic balancer.

    I guess I will need to save up and try to find a tractor shop that understands these old machines; like how to preload the bearing properly. I understand that the oil can get on the brakes, not sure when the last time brake work would have been done. Dad might have done it when he had new rims put on the rear wheels; the centres are original. However, that was a long time ago.

    With that said, my question is about the UTF fluid. If I go with the UTF fluid instead of the 90W gear oil that was in the tractor, will it exacerbate the problem?

  • Socket On The Way
  • I ordered a 2 inch 3/4 drive socket. I have a 3/4 inch drive bar so that should do me. I only have one 3/4 inch drive socket that I got for a job on an old Ford Taurus I use to own. It was smaller than 2 inch.

  • OK, since it was mentioned the nut could be loose, I decided to check; using a very large pair of channel pliers, I was able to turn the nut. I need to get the proper socket size. What is the size?

    My concern now is that I might have damaged something by using the tractor with a loose axle nut. Is it possible I have created some issues now? Please advise me. I had no idea to check the nut since I have never done any work on the wheels.

  • Socket size is 2". Was there a snap ring in that nut?

  • Yes, I assume you remove the snap ring, torque, then replace the ring. Is this like the castle nuts where you have to align it?

  • It is a pretty good little workout fixing the leak. But if you fix it your brakes will not get covered in sludge.

  • I believe it is a 2 inch socket, will check in abit. remember it should have lock ring on it to keep the nut from back off.

  • I would try to tighten the nut before doing anything else, the nut may be loose.

  • It did not make mine any worse when I switched. still leaks those, I got the parts to fix mine.

  • Re: Leaking Hub Seal
  • Good morning Kimberley. I remember when I had to tighten one of these nuts.....I was advised to use a two foot ratchet and to stand on it. I weigh 200 pounds so the thought was that 200X2' =400. It worked. Now I know better than to ask what you weigh but, using that equation you can figure it out. I had a breaker bar and a piece of pipe as an extension. Not hard. I believe I borrowed a socket and 3/4" ratchet set. Good luck. Assuming you weigh 100 pounds, you need a 4' bar length. Hee hee.

  • Re: Leaking Hub Seal
  • Ah, physics. Force times moment arm equals torque. Apply the force until the nut with the applied force at the moment arm does not result in rotation. I should have known this, I have studied physics. I also assume in this application that it is not super critical and if I go over a bit the system (axle threads and nut) won't fail.

  • Torque spec, I believe, is 450 lbs. 225@2 foot away and 125@4 feet away.
    I have also seen washers under the nut to force the hub onto the splines increasing the wedge fit of the hub on the splines and one of my 8N's out there looks to have a rubber washer, or some such, wedged in there to stop leakage.
    Some day I might take it apart to find out what's what.

  • Re: Leaking Hub Seal
  • If the splines on the axle and hub are worn, you can tighten the nut all you want and it will still be loose---like Bruce suggested---I found some thin washers that will just go over the splines, and still use the existing flat washer over the threads---torque the nut and it will force the splines to snug up and be tight. Also clean the splines off with brake cleaner and apply some silicone sealer in under the washers and if the leak isn't too bad it will stop it. If your brakes still hold good, the gear oil is leaking to the outside through the splines and not inside the brake drum. Dennis

  • How to test my braking on the Old Girl. It has been a year since I used the tractor; I got down a grade to get to the little valley but then I go down in low gear.
