One of my rear wheels keeps moving on the axle. I have tightened as tight as I can get it but eventually it wiil start to move again. I check it often because I would hate to see it com off. Also does anyone know where I can get parts for a 51 mower. (M John Deere)
 
Been a while since I looked one of these, but one quick thing you might want to try is replacing the bolts with new ones as they can stretch and make it hard to clamp down tight.
 
Make sure no one has ever put never seeze on the axle or hub. If so clean it all off. With that type of agent on there you can tighten too tight & crack the cast center.. Guess I would remove it & clean & check for worn parts. Put itall back together dry.
 
I would respectfully disagree with this. I use never seize on every wheel and hub I ever have apart. If you want to move the wheel ever again, use it. I use it on large and small tractors alike.

As for the original poster's question, it's likely the wheel has been ran loose too much and has worn wedges or if way too long, a bad wheel casting. You will want to take the wedges out of the wheel and inspect for wear. Hopefully some new wedges will fix your problem.
 

Use a torque wrench . As tight as you can get it can stretch the bolts and reduce the applied pressure .
As previously stated . New grade 8 bolts ,
New wedges , clean , dry , back off the push bolts .
Do not wait for the wheel to "loosen " . Retorque every hour of two of operation until it stays right .
 
Not knocking the product I have every color of it on my bench.. But if the customer is trying to keep a worn wheel hub from working/moving. Clean really good & put it back together dry. Never seeze works on everything except a worn wheel hub. When they are worn & keep working the customers tighten's the hub bolts / tighter & tighter then use's a longer wrench. With never seeze & he/she keeps tightening those bolts the 1500R cast center will crack. It is fine with me to disagree, the world would be boring with out.. LOL
 
Copper-bearing anti-seize compound might exhibit that tendency to a minor extent, but aluminum/nickel anti-seize should not. If an anti-sieze lubricant is suspected of causing difficulties, look further, since the REAL problem will be found elsewhere.

If you have an hour or two, ask me about flywheel hub retention on a National 1" six station coldformer. Before you do, look up the information regarding a retention device called a "Ringfeder" and then check back if any questions remain.

I've heard that in wheel nuts too. But I always used it on them. Never had one come loose on it's own.
 
Mike----good to hear from you. It's been a while. You once helped me with my A steering problem. I won't forget it.
