Doing an engine re-seal on my 95R100RT and got it down to the rear main seal and having a problem getting it out. Drilling a hole at 9 oclock, screwed in sheet metal screw and using claw hammer, tried several times, it distorted, started to move but then tore the screw out! All service manuals say pry it out, but not how. Before drilling another hole or two, any tips or hints would be appreciated and thanks in advance. JV
