Porter Cable Router Repair – Replacing the Bearing (Porter Cable Part # 33000-75)

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 with a 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, so doing it yourself means never having to do it alone. Let’s get started. I’ll begin by removing the base from the router. With the base removed, I’ll remove the collet. Next, I’ll remove the top cover from the router
motor. I’ll remove the slide switch from the speed
selector. With the cover removed, now remove the two
screws that secure the upper bearing carrier. Now I’ll remove the expansion screw that secures
the upper bearing to the armature shaft. I’ll place a large socket over the lower shaft. I’ll hold onto the socket to prevent the shaft
from rotating and then use an Allen wrench to remove the expansion screw. Now I can remove the upper bearing carrier
from the housing. Now use a vice and a socket to remove the
upper bearing from the upper bearing carrier. I’ll place the carrier over the vice jaws
and then use the socket on the inner race to tap the bearing out. Now install the new bearing. I’ll place it into the carrier and I’ll use
a punch to carefully tap the bearing back into the carrier. I want to be careful that I only hit the outer
race and not strike the bearing shield. Now reinstall the screws to secure the upper
bearing carrier. Now reinstall the expansion screw to secure
the upper bearing to the armature shaft. Now I can replace the speed selector switch
and the top motor cover. I’ll finish up by reinstalling the collet
and attaching the motor to the base. Now you know how to install a new bearing
in your power tool. Be sure to check back often for new videos
