I've pulled a lot of 2 piece hubs over the years and learned how from
someone who pulled a lot more in his day so I have not read any of what's
been posted on the subject until Jerry Hesch's nightmare posting. That
one sounds like the ONLY thing that would have worked is dissection of
the whole thing as he wound up doing however, I didn't notice ny
reference to what I've always done to get the stubborn ones off. That
method being to take a heavy hammer, even a small sledge if you have one,
and whack the end of the puller screw hard. It sounds as if this would
just drive the hub onto the shaft harder but it does something with a
vibration or a shock wave or something that pops the hub off the axle.
In tough cases, it will shoot the hub across the garage. Slide hammers
don't produce the same shock or vibration and don't do a whole lot by
comparison. My grandfather taught me to tighten the puller hard and then
hit the end of the screw. He learned how to pull hubs back in the days
of steam engines and was still doing it in the 1960s. He ran a rock mine
and had lots of cars, trucks and machinery so he did it a pretty fair
number of times between the 1920s and the 1960s. He didn't consider ithe
2 piece hub a problem. He said he method had never failed him His
last Imperial, and my current one, is a 1965 so it doesn't have the 2
piece axle. I still remember the day he gave me a brand new New Britain
hub puller and told me how to use it with a strong caution to stand to
one side when I hit that screw! Examining that partictlar puller, one of
the first features noticable is that the exposed end of the screw, the
end that you tighten it from, the very end of the shaft is rebated. That
way, as it gets dents and dings from getting whacked with the hammer, the
metal doesn't mushroom out and mess anything up.
If there was ever a case where this wouldn't work, it is surely the one
Jerry described but this method could make brake jobs a lot easier for
other folks who don't know and who don't have one stuck that bad.
