I've had a leak off and on since I got my G0709 new. The leak is between the Quick Change Gear Box and the gearbox casting plate (cover). When I take the cover off the gearbox and put it back on I just can't seem to get it to seal. I've tried using both a gasket and no gasket , gasket sealer and no gasket sealer. Has anyone else had this problem or any suggestions on how to seal the Gear box. I've got a couple more gaskets coming and am going to try again. It sure would be nice to not have this leak. Anyone out there with any suggestions? Also would anyone venture a torque range and tightening sequence for the screws and does anyone know of a gasket sealer that kinda expands to keep leaks from happening???
