Hey, <br /><br />I'm rebuilding this 1978 70hp mercury and got everything going well, except for one thing, I can't get the top timing gear loose to replace the top bearing, and yes the top bearing is shot so I do need to replace it!<br /><br />Anybody got a tip on how to get this gear off the crankshaft, I put a flywheel puller on there and it didn't really get it, I think it's just rusted too much! What can I do?<br /><br />Thanks,<br /><br />Richard
