Band Saw Repair – Replacing Cam Followers (Milwaukee Part # 02-25-0260)


Squealing sound coming from your Portaband? You might have a bad cam follower. The cam follower is attached to the saw’s
guide blocks. There are a total of six of them, three on
the front guide and three on the back. Four support the blade from moving side-to-side
which helps the saw cut straight, the other two support the back of the blades so it doesn’t
track off the tire when you are cutting. The cam followers are small bearings and eventually
they will wear out and seize. A worn cam follower can create a squealing
sound when it fails. The cam followers should be inspected occasionally
and replaced when they show signs of failure in order to keep your saw cutting properly. Replacing a cam follower 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. There are six cam followers on your saw, three
on each guide block. If you’re removing either of these two cam
followers you can easily just get a screwdriver in and take them off but if you’re removing
either of the other two you can’t get access with a screwdriver to remove them, so you
have to remove the guide block first. If you’re removing the guide block on the
front of the saw there’s two screws that secure it in place. The one on the rear has the same two screws
plus the bumper, so if you’re doing the one on the rear you’ll need to remove the bumper
first and then the guide block. I’ll be working on the front guide block,
so first I’ll remove this screw. Now I flip the saw over so I can remove the
second screw on the guide block. This screw is somewhat hard to get to but
if you adjust the tension to bring the housing as far forward or as back it’ll go, strike
it a little, bring it all the way back and you should be able to get your screwdriver
in to remove that second screw. Now we can remove the bad cam-follower from
the block and install the new one and these just screw into place. You’ll need a small screwdriver to do this. The problem is most small screwdrivers are
also quite thin and the opening in the screw is quite large. If you use your small screwdriver there’s
enough play that you may break the tip off of the screwdriver. A solution to this is to take an old screwdriver
and modify it. Here I’ve taken a very large screwdriver and
ground the tip down so that’s the proper width to fit into the screw but still quite thick
so it won’t break off. I can go ahead and remove the cam follower. Now use a rag to clean up the guide block
and install the new cam follower. Apply a little bit of red Loctite to the threads
and screw it back into the guide block. Now I can reinstall the guide block. There’s two different length screws used. The short one goes through the housing and
into the block and then on the other side we use the longer one through the block and
into the housing. Now long screw on this side. Be sure to check back often for new videos
