Helpful Tips: Removing Perch Bolts From The Front Axle, Model A

[David R.]

Ditto on the ATF and acetone but so many get offended when you recommend it for some reason? Only drawback is the acetone tends to evaporate in my pump oiler, so I mix as needed. Best I’ve tried.

If a Model "A" owner got in an accident, I would think the status of the front axle would be the least of his worries.

Probably disapproved so Ford could sell more new axles.

this might be in the realm of the absurd, but would dry ice, or even whatever level of liquid nitrogen one can buy on E-Bay, affect how tight the perch is stuck?

I'm encouraged by the success stories in this thread, and I especially wish to thank those who contributed stories of their experience. I'll post my results in a few weeks when the job is done.

Hopefully others can use this thread to help tackle this weirdly 'Ford' type of project.
I made it a point to use key words in the title to help others find this thread in the future.

My method was to clamp the axle/wishbone assembly to a bench that was anchored to the floor. Lots of Kroil was involved. I put a big pipe wrench on the perch bolt, and a five foot long pipe on the wrench handle. Give me a lever long enough.... Anyway, I was able to turn it maybe an 1/8 inch. Then I turned it the other direction, and I kept switching directions and each time I got a little bit more rotation and a little looser. I kept at this until it was fairly loose, and I was able to kind of "unscrew" it out with a little tapping to help it along. It was quite a workout.

I’m with Will N on lots of Kroil and a bit of heat before the Kroil. I then let it sit for a day or so,give it a tap once in awhile to let the Kroil do its thing. I then use a air hammer and protect the threads with the nut and flat chisel on the end,they come out like warm butter.

Hop,

"they come out like warm butter" sounds stimulating!.

"a bit of heat". How much heat, and applied where? What color was the metal when you heated it?
