Makita Multi-Tool Repair – Replacing the Bearing (Makita Part # 210023-2)

“Power tools use many bearings to allow various
components to rotate. Over time a ball bearing will wear and begin
to fail. A bearing that is failing will usually give
warning, often with a squeaking or a squealing sound. Replacing a ball bearing is a repair that
you can do yourself, and I’m going to show you how. Hi, I’m Mark Sodja. Do-it-yourself repairs like these are easier
than you might think. From lawn machines to cordless drills, kitchen
mixers, outdoor grills, our how-to videos will walk you through each repair from start
to finish, so doing it yourself means never having to do it alone. Let’s get started. I’ll begin by removing the rear cover from
the tool. Now remove the brush tension springs from
the brushes. Now remove the gear housing cover. Now remove the screws that secure the gear
housing to the motor assembly. I’ll separate the two halves. Next, I’ll remove the magnetic ring, it’s
secured with a retaining ring. I’ll use a pick to start removing the ring,
and then get a small screwdriver underneath it. If the ring is bent during removal you’ll
need to replace it. Now I can remove the magnetic ring and the
wavy washer. Now I can remove the bearing. I’ll use a bearing separator to do that. I place the separator over the bearing and
tighten it up. Now I’ll place the separator on top of my
vise jaws and use a rubber mallet to tap the armature away from the bearing. Now I can install the new bearing. I’ll place it over the armature shaft and
use a socket that has a diameter about the same as the inner race to tap it into place. Now replace the wavy washer, the magnetic
ring, and secure it with the retaining ring. Again I’ll use a socket to install the retaining
ring. Now reinstall the gearbox and armature assembly
back into the housing. I’ll replace the cover, and I’ll place the
brush springs back over the top of the brush. I’ll reinstall the rear housing, and secure
it with the screw. That’s all it takes to replace the ball bearing
in your power tool. Be sure to check back often for new videos
