Just thinking out loud here. I have not tried this. There are impact drills that have an impact only mode (Hilti Brand comes to mine). They can be used to drive ground rods in the ground. This type of impact might help.
Any tips for removing a pin from the backhoe ?

SSDoxie (Dennis) had good advice and recognized the problem on the first page.
Other then what he said I would only add:
What I would first do is get the hoe in a non weight bearing position, bucket on the ground and the dipper stick straight up, then maneuvering the boom so the loose side of the pin appears to be in the center of the hole, if it moves.
Next I would hammer on the flag to see if the flag and pin rotate in the bore. That would tell you if the pin is seized.
Then follow Dennis' advice.

Learned a lot from the advice given, thank you all.
The pin has been in a non load bearing position and it is siezed in the centre.
It is worn and free moving in both outer load bearing points.
We are going to cut the flag off and drive temporary bushes in both sides so as we can use the machine to dig a trench etc which is what it was bought for.
Two out of the three rams need new seals so they are coming off to be repaired, the machine will be then good for work until we can get around to renewing everything.
When the work is done then we will take the backhoe to pieces and refurbish it, I think that is the best plan.
thanks again for all your help guys

Just a bit of advice......That pin is hardend steel. To much heat and may snap right off. The Flag is the keeper for the pin. From the looks of it the pin has been like this for a long while. May want to do like one post said"weld the flag to the boom and rotate the pin around a bit". Although i really do not think that will get this unit back up and running. Also you will have a hard time finding spacers for the ends.May try to find Babbet metal and make your own. Not the best but may work.....Good Luck

Before I cut the flag off, I would put a large pipe or crescent wrench on it and a LONG (6 feet) cheater bar for added leverage and see if you can get it to rotate. The flags shape would allow a big wrench to really get a good bite. If you can break the seize free, the pin may be able to be driven out from the grease zerk side. You might also find that after the flag is cut off, you can drive the pin out from that side. Point being, before I cut the flag off, I would use it to help try to break the pin free.

Do you have a good welder you can use? I would weld a long bar to that flag for leverage and then try to twist it back and forth to loosen it up.

I'm looking for some tube to hammer in and take up the wear in the nipple end, then I'll cut off the flag and do the same to that end.
This will get us up and working and we can worry about it during the summer.
May need some serious cutting and welding to get it right.
That is the only pin that we have trouble with now, rams away for resealing and ordered some new grease nipples

If it's froze up in the center it'll need some "Florida Summer Sunshine in a Bottle" (oxy-acet torch)......:thumbsup:
