Return of the 8n hydraulic arm question

The short version. I have 2 lift covers. I'm trying to make one good one from the two of them.

One everything works except it has 1 broken lift arm and some broken peices on the casting. The other works but the pin that rides the cam in position mode needs replacing. Parts books says the pin is a simple a dowel. I've disasembled the one w/broken arm. I checked for threads and didn't see any. Tried to press out the pin and it wouldn't budge (20 ton press). How much force is required to get the pin out?

I would use the arm entirely except that it is (1) bent and (2) the wrong part number. the bent number is 8N 524 not 8N 504.

I'm going to heat up the arm and see if that relieves enough pressure to get the pin out. Any other ideas or better solutions to my predicament?

Thanks,

Roger.

I did solve the pin issue,,,, minor equipment/setup problem. It was stubborn and whined a bit but finally let go.
