I slowly getting things fixed on this 1816. I bought four sets of seal kits and did the one lift cylinder today. As I was sliding rod back into cylinder I noticed kept binding- Pulled it back out only to see the rod has a 'arch' to it. No gouges /grooves, just a gradual arch. I called around and so far no places will straighten it. I heard it can be done though. so.. anybody straightened one at home before? if not.. Anybody know of a good replacement one that will have the same travel, ect?
