[s-cars] Tools for pressing hubs and bearings

[Fred Munro]

Dave;

I have a 12-ton shop press with a 3" platen, but when I had to do my front
bearings I went with the Audi "Hub Shark"-type tool. The jigging to properly
support the bearing housing while struggling to position the strut seemed to
be fraught with all sorts of potential for disaster - so I took the easy way
out! As you know, some of these bearings are in there tight. I don't know if
12 tons would do some of them. I've stretched my press to the limit at times
on rear bearings. Even with a 1" impact gun, the Audi tool wouldn't move one
front bearing and I had to resort to a 3/4" drive Johnson bar with a 6-foot
cheater to move it.
If you do get the press and need a larger platen cap, you might be able to
fab one from a 2.5" steel pipe end cap if you know someone with a lathe. You
want things to be square working at high press loads, otherwise pieces tend
to fly everywhere if something lets go.

I need to change the front hub bearings on my UrS4.  I am thinking of buying
a 12 ton shop press
(H-frame with bottle jack).  However, it would only come with a 1" (or so)
pressing "pin".  I know
 I will need something much larger, e.g. 3" to press the bearing out.  What
have people used to do
this? (I am hoping for off the shelf Home Depot-type cast iron plumbing
bits).

TIA
