Custom Pin Spanner Wrench for John Deere Cylinder

[Don52]

Thanks.



I have a bunch of pin spanners with varying degrees of robustness. Due to the age of the back hoe I was worried that the cap might be rusted in place so I built a fairly robust one.



I agree. I have noticed that 3/4" pipe is fairly thin...

My friend John tried it out. Here is what he had to say:

The ram looks dented in the above picture. It is just drops of water on the ram. Here is a picture after John wiped it off:

I built a custom pin spanner for my friend John, so that he could replace the piston seals on his John Deere backhoe. I made it from 1 inch stock, which I have kicking around. We tried to buy a standard one, but unfortunately the ancient John Deere tractor didn’t have a standard distance between holes...
