I've been wrestling with the free wheeling pin on my G-10 for several days now and the thing is starting to come out. It takes a very strong hit with a heavy hammer to budge it at all, even after what feels like gallons of PB blaster have been applied. I have two questions for those who have battled these corroded-in-place pins before me.
First, my ultimate goal is to end up with a pin that I can easily move from the free to locked positions. I'm wondering if this is a reasonable goal and what I have to do to reach it. I'm obviously planning on greasing the pin liberally after I get it completely out and before it goes back in. What I'm wondering is whether any of you have soaked the pin in a solvent to get some of the corrosion off in order to get the diameter back to spec. Any thoughts on this? I'm debating using one of my favorite solvents -- Coca Cola -- for a 2 day soak to get this thing cleaned up.
Second, there is some sort of vent or grease fitting on the axle housing that I'm a bit bewildered by. Stock, it should have been nearly flush with the housing as near as I can tell, but it now has a metal piece that appears to be jammed into the opening and is interfering with the pin's trajectory if I want it completely out (see the picture I've attached). What should I do with this? Is it ok to rip that puppy out completely, just leaving the vent/access?
