This may be a dumb question...ok, I may have a few dumb questions but, here goes.

I have a 2005 S175 with around 5200 hrs. It has never given me trouble until......I had 50 yards of fill dumped, of course, right in the middle of my driveway and, it had to be moved relatively quickly. As I was moving it to my back yard, I suddenly noticed what, at first looked like water pockets in the fill I got (a lot of clay so it didn't really surprise me) but, as I backed up further, I could see it was oil. I looked to the side and saw that the side of my house was covered in oil...literally covered up to about 20 feet high and got out to see what was wrong. I had blown the wiper out of my lift cylinder and dumped most of my oil on my driveway. This being a rush job, I called my local dealer and they didn't have the seal set so, I had them overnighted....aftermarket parts (not sure if that is where my problem lies).

I got the seals and wrangled my wife into helping me and we changed out the seals on both cylinders. Everything inside looked fine...no scoring, pitting etc except a small chip taken out of the metal flat on the piston (not even sure how that could have happened but, I would guess at an earlier time when seals were done). Anyway, got everything back together, and, as I was finishing relocating the fill, I noticed that my lift arms would drift down about an inch and then stop. They may have been drifting still but, if so, it was so slow and so minimal you couldn't see it. To be honest, I can't say if they were drifting before the cylinders were rebuilt or not...they could have been.

I researched problems that could make the arms drift and the only two that appear to be possibilities are, a damaged seal (possible) or linkage not adjusted correctly (also possible). I started yesterday playing with the linkage and after trying different holes, I don't think that is the problem but, I discovered an issue I can't figure out...my first stupid question....how do you get rusted bolts out of the foot pedal mount? I have a pretty extensive shop but, I have tried everything to get them out, cut them off, etc. I don't have any cutting tools that I can fit into that area and get at them. I really don't want to torch them off but, if that is my only choice I will. Have any of you found a way to do it without a torch?

My second question which is probably the most important question, is about the lift drift. Is there some sort of equalizing valve that would allow both arms to drift at the same time?...I had it in my head that if one sides seal was bad, the other side would keep it from drifting. I guess its also possible (likely?) that the seal kits I got were not the correct size but everything seemed to match up okay. Is there anything else I should be looking for that could cause the issue?

Sorry for the book and the dumb questions and thanks for any knowledge you can pass on.
 
Thanks for reaching out. The problem is with the lift cylinder, tilt works fine. I changed all of the parts included in the rebuild kit including the piston seal and the o-ring under it.
There could actually still be some air in the system. This would cause the arms to drop a little and stop. It takes quite a bit of slow full movement and letting the bubbles dissipate in the tank and refilling the tank before all of the air is out of the system.

Since you were in a hurry, I doubt that you took the time needed to do this properly. Try lifting the arms up and down, full motion, slowly a few times and see if bubbles show up in the hydraulic fluid tank. If they do, then you've still got air in the system. Make sure to keep an eye on the fluid level and keep it full otherwise you will introduce more air.

Hopefully this is the issue and it will go away after the air is out.
