This project is the most I've ever ventured into a ski....I CANNOT move the cover over the "c" in front of bellows on shaft for bearing replacement...Any tricks? I was able to get a wood 2x4 against the block and tried prying with a screwdriver, felt like I had some pretty good pressure on it, shaft moved out but flange wouldn't budge!..sprayed some mmo liberaly in shaft and tilted ski way back, hopefully this will loosen..I also tapped on it and even tried a little plumbers pliers...all NG...whatcha all do?
