Hinge pin removal question
On my 1991 I want ot remove the hinge pins to repair, weld, the screen door.
The pins appear to have an allen slot at the bottom. One, is the allen English or Metric? I ask this because they seam to be sloppy English and there fore might slip if i put heavy pressure on them.
Two, what is best to soak the top threaded section of the pin with to hopefully loosen them before I attempt to remove them?
