Makita Plunge Router Repair – Replacing the Bearing (Makita Part # 211380-1)


Power tools use many 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 the 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 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 separating
the motor assembly from the base. To separate the two halves I’ll remove the
adjustment handle. Now I can pull the motor assembly away from
the base. Now I’ll remove the motor brushes. Next, I’ll remove the side handles. I’ll also remove the side cover as it’ll be
necessary to have it removed when I reinstall the handle later. Now I’ll separate the lower half of the motor
and the armature from the upper half. As I separate the two halves, I need to make
sure that I remove the wiring harness that goes to the LED light.Now I’ll remove the
collet and the lock ring. I need to remove the retaining ring. To do that I’ll clamp the armature into my
vise. I’ll wrap a rag around the armature so I don’t
damage it add just enough tension so the armature doesn’t rotate within the vise. Then I’ll use a pair of adjustable pliers
to remove the retaining ring. Now I’ll remove the armature from the bearing. To do that I’ll use a rubber mallet. You need to make sure you use a rubber mallet
here as using a regular hammer will damage the spindle.Now I can remove the bearing from
the housing. First, I’ll remove the retaining ring. With the retaining ring removed, I can remove
the bearing from the housing and it comes out quite easily. Now I can install the new bearing. I’ll place it in the housing and gently tap
it into place. Now I’ll replace the retainer. I can reinstall the armature into the base. Again, I’ll use a rubber mallet to tap the
base down onto the armature shaft and I’ll reinstall the retaining ring. I’ll replace the locking ring and secure it
with the screws. I’ll replace the collet as well.I’m ready
to reinstall the lower half of the motor to the upper. I want to make sure I installed the baffle
and then I’ll slide the armature through the field. I’ll need a pause to reconnect the harness
for the LED light. With the harness reconnected I can slide the
two halves together, I want to make sure I don’t pinch those wires and then I can secure
it with the screws. I’ll reinstall the switch side handle. I’ll line the handle with the housing and
secure it with the screw. Now I’ll reinstall the trigger and the lock
button and replace the side cover and I’ll replace
the wiring cover. Now I can replace the other side handle and
I can replace the brushes. I’ll finish up by reinstalling the motor assembly
to the base.That’s how you can replace the bearing in your power
tool. Be sure to check back often for new videos
