| - | * The LEFT mount will not come out easy if it is OUT OF ROUND. Turn it like 180deg and out at a angle.. it helps to REMOVE THE LOWER dogbone and rock the rear of the engine around... the NEW "round" mount will go in much easier... the RIGHT mount should not be a problem it will slide out once the AXLE shaft (the one with the 3 screws that break) is knocked out.... it doesnt matter the "shape" of the old mount it will come out pretty easy... but the primary and the frame will create some issues getting the RIGHT mount out IF it is droopy.

| - | * Replace the swing arm bearing when you have it apart... and above all else... follow the TSB for reinstalling the rear brake don't cross thread the pivot bolt. ((04xl1200c http://xlforum.net/forums/showthread.php?t=1526368&highlight=motor+mounts&page=6)) | + | |
| - | * When you have the swingarm out, use a few sockets and some all thread (a bolt could work as well) in a vise to press the bearings out. ((Screw Loose Dan http://xlforum.net/forums/showthread.php?postid=5569081#post5569081)) There might be some surface rust in there, just soak it with some rust solvent for a couple of hours before you press it.
