Rebuilding a couple of compressors.
One is a Kellogg American 331TV. Removing the tapered roller bearings on the crank is a pain.
Not enough shoulder to drive it off, a little too close to those lead blobs Kellogg welds on for crank counterweights, and my bearing splitters kept fracturing off the inner race shoulders if I pulled on them.
^ No Space.
^1st step chisel off the cage and toss the bearings.
^Took a couple of hours and made a bearing splitter that fits out of 4140 annealed. I will heat treat it later when I have a few things else to heat treat.
^That took the fight out of it.
^And a Dragon's tooth to remove the valve caps on a couple of Saylor Beall 705s old version (cast iron rods) that I am also rebuilding.
Made it out of 4340 annealed, ditto on heat treating. Tried a piece of mild steel bar stock and candy caned it on a stuck one, O1 same results. This finally got it.
^ Valve tools from 4140 Prehard.
