THE JAWS ON MY MAKITA SANDER WOULD NO LONGER GRASP THE SANDPAPER

THE TEETH WERE WORN DOWN ON THE JAWS AND NOT GRABBING THE SANDPAPER. THE SANDPAPER WAS COMING OFF MY MAKITA OSCILLATING PALM SANDER. I HAD IT SINCE THE 80'S I THINK. BUT THERE IS NOTHING ELSE WRONG WITH IT SO WHY NOT REVIVE IT?
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..

Refurb an older Makita BO4550 sander

Picked this up used sander to complete a refinishing project. It's an oldie but goodie. It had good bones, extremely well constructed. Ultimately I replaced the sandpaper clamps and retaining clips, the nylon feet that hold the base, the brushes and a seal.
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.
