Take the front spring cips (u-bolts) and the spring clip plate and use it to press out the perch. Use the usual precautions to avoid mushrooming the perch. Tighten, Kroil, etc helps, and will be needed...fwiw,jm
Good point! Neverseize is good. As a apprentice machinist, we used to use "White Lead" for the same job. I haven't seen white lead in quite a few years, political correctness may have finished it. There's always plumbers "Pipe dope" which should do the same thing. Even just spraying the parts with aluminum paint should accomplish the same things. Any non ferrous compund between the iron/steel parts should prevent the parts rusting together.
