My dad broke the Oliver 9 bolt hub on his Super H this morning. He overtightened it and cracked it. Is there any way at all to fix this. I know it is cast so there may not be a way.
 
Well, cast CAN be welded, and works well when done right. The key here is that you need to take it to a GOOD welder who knows what they are doing. Welding cast is not like welding steel, but that doesn't mean that you can't have it done and get a successful repair. it can also be brazed, but that will end up being very visible, as the amount of brass required to make it strong and work is much different that a weld. but that is also an option.

Find a good welder, and they can probably fix it. In my area, there are lots of welders, but only a couple know how to weld cast, and they actually advertise that they do.

do a little research, and get a good welder.
 
Depends if it is cast steel or cast iron . Cast steel can be welded and SHOULD be ok Cast iron can be welded but as far as strength ??? i would not trust it on hub . Yes i can weld and weld well good enough to do high pressure welds and at one time had the certificate . To even get close to the org. strength you will have to PRE heat and hold the heat while welding then it must cool vary slowly over time . and MOST people can not do this . It may be easier to just get a used hub and start over . And this time use a torque wrench .
 
If it is a working tractor Imagine what the effect would be if it broke while moving. Not a good idea. Were it mine I would replace it. Make sure the shaft and hub are smooth and clean before assembly. A single bit of dirt or paint can creat point loading on tightening that will break them every time. Jim
 
Well, Tractor Vet and Jim both make good points. Cast Iron is pretty cantankerous to weld, and yes, it has to be taken up to temp, kept there while welding, then have a very controlled cool down. Most welders don't have the furnace to do that.

If you can find a new one, probably the safest route. If it is cast steel, then again, i agree with Tractor Vet.
 
Now as to the torque on them hubs (1) i would have to know the size of the u bolt and since i am not the Guru of Guru of Olivers i would have to look tha up. Ask the guys on the Oliver board.
