Assume I should remove the allen screw first before using jaw puller? Will turn right side up and soak the shaft in tranny fluid. When trying to remove the allen screw I am using a 5/32 although seems to be not a perfect fit. If go to a 9/64 it is to big and of coarse the metric side a 4mm too big and a 3mm too small.2 or 3 jaw puller. PBlaster, Liquid Wrench Penetrating Oil or 50/50 Acetone/Tranny Fluid will do better than WD40. Heat up the Lovejoy with a torch.
