Here's the sequence of moves I came up with to put the lift cylinder back on.
1. Insert the piston rod into the cylinder tube such that it comes out the other side about 3/4 to 1".
2. Insert the base plate such that the steel hydraulic line protruding from it is in the lowest position around the circle of the cylinder base. This gives the largest clearance to the 1/2" pin holding the cylinder in place at the bottom.
2. Screw in the top hydraulic line, by turning the cylinder. Yes, the line does not rotate, so the cylinder needs to rotate. I went hand tight.
3. Push both the base plate and cylinder rod in until the base plate clears the pin holes. I used the hammer handle to do this.
4. Insert a large screw driver in the pin holes at the bottom of the cylinder to have some counter force, and tighten the upper hydraulic line with the 5/8 wrench. I suppose you can do this after you install the cylinder, but at this point I found more room than at the end.
5. Hook up the lower hydraulic line. This can be done with a 5/8 wrench and another counter wrench, as the line has a sleeve nut.
6. Pull the cylinder rod out as far as it goes and rotate it so that the upper pin has a path clear of the upper hydraulic line. At this point the cylinder or rod are not pinned, and hanging only on the hydraulic lines.
7. Position the cylinder rod and install the pin.
8. Rotate the cylinder to the bottom holes are aligned with the holes in the frame mount, and insert the pin.
9. Put the split pins on.
10. Replenish hydraulic oil as needed and turn the tractor on, moving the hitch up and down a few times. Replenish oil as needed.
This worked for me, ymmv
