When I mention blocking up the loader, I meant to rest it with the bucket slightly off the ground, so that the cylinders could be retracted enough to be removed, not really working under it. Though I do have a set of C Channel made to hold the loader up in the air during winter storage so it takes up less space. Those slip over the cylinder rods and then the weight rests on the C channel. That wouldn't work for the job I need to do.
What part of the cylinder requires a press?
Now if you can get the kingpins out of my 80, that would be awesome
