Support it around the edge of the clutch case and stick a bar through the hole in the center through the axle gear and press against the cross shaft. That should seperate them.
Surprise! It all came apart just fine. There was a curl, but it seemed more like it was wedged in the side and not under. I took a tiny skim cut on the OD of the factory half. It's still a press fit but I can do it easily now.
Now the bad news... I gutted both halves and bolted them up empty, stuck it in the housing and put some preload on the bearings. This "new" billet half is 0.003" out of round and has 0.015" runout on the backside. The face where the gear mounts has 0.007" runout. The high spots seem to coincide, so it's prolly a poor machining job and didn't get caught in QC. Have e-mailed QP and am awaiting their response.
