Makita Planer Repair – Replacing the Plane Bearings (Makita Part # 214251-1)


The plane bearing support your planers infeed
and outfeed rollers. The bearings allow the rollers to rotate and
have a spring above them so the rollers can adjust to different workpiece thicknesses. Over time, the plane bearings can wear. This can cause play in the rollers or the
bearings can gall, causing a roller to cease. Replacing the plane bearings 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 side covers from
the pointer. Now I can remove the support bracket. Now, remove the chain tensioner. Now, remove the chain. I’ve located the master link and I’ll go ahead
and remove it. I’ll use the pliers to remove the clip. Then, I can pull the outer link off and the
master link itself. With the master link removed, now I can remove
the chain. Now, we can remove the sprocket. I’ll keep the sprocket from rotating with
a pair of needle-nose pliers. Then use an Allen wrench to remove the screw.Now,
I’ll raise the cutter head up as far as it’ll go. I’ll tip the planer onto its side. The rollers are held in place with a couple
of clamping brackets. We’ll go ahead and remove them. With the brackets removed, now I can pull
the roller away from the housing. With the roller removed from the planer, I
can go ahead and replace the bearings. I’ll pull the old bearings away from the shaft
and install the new ones. This assembly is ready to go back into the
planer. As I install the assembly back into the planer,
I want to make sure that I have the end of the roller that accepts the sprocket on the
side of the pointer where the chain is located.I align the bearings with the housing and slide
them back in. Now, I’ll secure the roller with the clips. Now, I’ll reinstall the sprocket. I place it over the shaft and I’ll re-secure
it with the washer and the screw. Now, I’ll reinstall the chain. I’ll work the chain around the sprockets. I want to try to make sure as I do this that
the master link ends up in a convenient place to reinstall it such as here at the bottom. I’ll place the master link through the chain
and then lock the link in place with the clip. Now, I can reinstall the chain tensioner. To install it, I’ll take the straight leg
of the tensioner and align it with this bracket on the casting.Then, I’ll take the screw with
the washers and the spacer, place it through the tensioner and begin to thread it into
the housing. At this point, I’ll leave it loose. Then, I can grab the J-portion of the tensioner
and pull it down behind the chain like that. Now, with the screwdriver, I’ll go ahead and
tighten the screw that secures the tensioner. Now, I’ll reinstall the support bracket. Now, I can replace the side covers. Now you know how to install new plane bearings
