I have a 500 series loader with leaking cylinders. In the past, I have only had to replace the inner and outer o-rings on the piston. The packing was good.

Does anyone know the size of the inner and outer o-rings? I really don't need the whole kit.

I tried fixing my 500 loader cylinders myself. I failed because my rods were slightly bent. The seals leaked when the rod was in the middle but didn't leak fully extended. I bought two agco seal kits and then bought two new cylinders. I don't know the answer to your question but I hope you don't have bent rods like me. I think agco has all.of the part numbers you need to figure out what you need.

Alex at A&W Tractor has seal kits for the 500 loader. I got 4 kits from him for my 185 this spring. Andy

Did you remember to install the 'back-up washer' 343390 with the smaller inner 'O' ring ?

Thanks for the reminder. I am sure the diagram shows what side of the o-ring the back up washer goes.
