Hey, 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!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?Thanks,Richard

I don't know your particular motor, but have you considered applying some heat? Sometimes the expansion and contraction will break a part free, and your puller can do its job. Since you are replacing the bearing anyway, try waving a torch at it for a bit.No guarantees though...
