Are there two styles of piston liners?

jpmachine · Apr 17, 2016

Piston liners seem to either be ringed for o-rings or intended for the o- rings to be in the block. I think I have the wrong liners but does anyone really understand these?

Are the blocks different? Are the liners interchangeable? It is sunday so I have to wait til tomorrow to call but I am afraid I have received the wrong liners for my John deere 450.

Any comments would be appreciated.

Can you not compare to what you removed from the unit? Where are the old liners?

The old ones have groves for the o-rings and the new ones don't and according to the description for the new ones from the internet they are for o-rings in the block. I am concerned that I will need to return them for the other style.

I received the wrong sleeves for my 219 engine in my JD 2520 tractor. Company then sent the other type. I assume if not exactly the same, your engine is basically the same as mine.
