8N Sleeve Removal
I had the same problem. Read all of the previous postings. Finally after trying to pull
the sleeves out intact (very difficult to catch the 0.040 lip) I crushed each and
removed them. Took about 15 minutes.
I ground an old Craftsman screwing tool, one with a 1/4 inch blade, to the
approximate radius of the casting and a slight radius on the bottom. Then very
carefully I tapped the 0.040 inch sleeve inwards from the top crushing it into the
cylinder with each tap. Since the screw driver is rather short I had to flip the block
and to the same thing from the bottom aligning the crush apex begin from the top.
The sleeves flaked and broke into pieces when I used a larger tool, like the one
pictured in the literature. This made it impossible to get a continuous crush.
I tried several other approaches and this seemed to work just fine.
I cannot recommend this procedure with the so called 0.090 sleeves but it seems to
work with the 0.040 sleeves. I'm rebuilding a replacement block. It already had the
sleeve for #1 removed. I noticed a small gouge in the #1 casting, looks like someone
used a similar method removing that sleeve, but was a bit more aggressive. So be
very careful not to gouge your casting.
Good luck.
