REMOVE THE FOUR SCREWS IN THE BOTTOM OF THE PAD, AND FLIP THE LEVERS SO THERE IS NO PRESSURE ON THE JAWS. I HAD TO WIGGLE THE PAD SO THE TABS ON THE JAWS WOULD SLIP OUT FROM UNDER WHERE THEY FIT WHEN THE THING IS ASSEMBLED.
BUT I DID NOT HAVE TO REMOVE ANYTHING ELSE IN ORDER TO REMOVE THE OLD AND PUT IN THE NEW. COOL..
Normal wear and tear.

Cleanup was extensive, I used 600 grit wet/dry paper VERY lightly on the armature to remove accumulated oxidation. All the bearings were tight, no attention needed.
Assembled the old sander, fortunately there are plenty of sources of exploded parts list to make sure you gat it back together properly.
In the end, I now have a Makita 1/4 sheet sander that runs like brand new and since all the wearable parts have been replaced should last a very long time. You would be hard pressed to find a new unit with this quality unless you plan to spend a great deal.
