Makita Band Saw Repair – Replacing the Armature Bearing (Makita Part # 211031-6)

“Power tools use mini ball 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 the squeaking or 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 walk you through each repair from start to
finish. Doing it yourself means never having to do
it alone. Let’s get started, I’ll begin by removing
the motor brushes. Now remove the wheel guards and the blade
guard. Now remove the top half of the switch handle
housing. I’ll flip the saw over and remove the two
screws on the back and I’ll pull the rest of the handle away from the saw and just leave
it loose. Next I remove the four screws that secure
the rear housing to the motor housing and I’ll separate the two halves. Now remove the armature from the gearbox. I’ll use a bearing separator to remove the
bearing and place the separator over the bearing and tighten it up. Then I place the separator over the jaws of
my vice and I’ll use a rubber mallet to tap the armature shaft free from the bearing. Now I can install the new bearing. I’ll place it onto the armature shaft and
I’ll use a socket that has a diameter about the same as the inner race on the bearing
to install it. I’ll tap in place with a rubber mallet and
now I can reinstall the armature. Now we’ll reconnect the two halves of the
saw. I’ll reinstall the baffle and slide the armature
back into the motor housing. I’ll secure the two housings with the screws. Now, I can reassemble the handle. First I’ll reattach the rear half of the handle. I will align with the housing and secure it
with the screws. I’ll realign the switch and all the wires
so I can install the other half of the housing. Now replace the wheel guard and blade guard
and I’ll finish by reinstalling the brushes and now you know how to replace a bearing
in your power tool. Be sure to check back often for new videos
and expert advice. If you found this video helpful, give us a
