The procedures are straight forward enough, but there is one process that concerns me. Its not talked about very much, and I've been able to pick up only a couple tips from previous posts.
As the title says, it's the process of removing the perch bolts from the front axle. They've been living in there for 90 years, and I think they like it in there. I want to evict them, and I'll kill them to do it.
Two things I've read:
1. Don't apply heat to the axle on account of axle tempering issues.
2. Previous accounts record that just under 20 tons of force was required to press the bolts out (I'll bet this value can vary a lot).
I'd sure hate to get stonewalled when I get to this step, so I'm doing my research now. I was hoping to just pick up another axle and do the work in advance, but finding a decent non-heated axle from a reputable source has been elusive.
I will say that I have been periodically applying liberal amounts of Kroil and PB Blaster (alternately) for several months now, and more frequently in recent weeks. I hesitate to share this lest this thread turn into a Master Chef Show of cooking oils.
Barn-ers, could you please share you experience and "how-to" in removing the perch bolts from the axle?
Were you successful?

I welded two brackets on the end of a six foot pipe with 5/8" holes in them so they straddle the spring eye. then run a bolt through the spring eye and brackets and tighten. Now you have enough leverage to rotate the eyebolt back and forth with penetrating oil and they will come out.
I have taken a lot of them out and have never heated an axle.
