Planer Repair – Replacing the Roller (DeWALT Part # 5140006-85)

“There are two feed rollers of your plainer,
an infeed roller and an outfeed roller. The rollers feed the stock through the planer
and hold it firmly against the tables, so you get a nice smooth finish. The roller is made of rubber on a steel shaft. Over time, the rubber will harden reducing
its ability to grip the wood which will cause it to slip. The steel shaft is supported on either end
by bushings. After years of use, the bushings will fail. Sometimes a failed bushing will also score
the lower shaft. Replacing your planer’s rollers is a repair
that you can do yourself and I’m going to show you how. Advertisement: Hi, I’m Mark Sodja. Do it yourself with 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. Mark: I’ll begin by removing the side covers
from the planer. [pause 00:01:00]
Mark: Now I’m going to raise the cutter head as high
as it will go, and I’ll lay the planer onto its front. Now remove the gearbox cover. Keep in mind at this point going forward,
the knives are exposed. Next, I’ll remove the sprockets and chains. The sprockets are secured with retaining rings. [pause 00:02:39]
Mark: First, I’ll remove the chain between the two rollers and then the chain from the outfeed roller
to the motor. There’s a spacer that goes behind the sprocket
on the infeed roller, I’ll go ahead and remove that as well. The roller is held in place with a retaining
bracket on either end. I’ll go ahead and remove both retaining brackets. Keep in mind there is a spring behind the
roller bushing that will tend to push the roller out as you do this. [pause 00:03:55]
Mark: Now I can just simply pull the roller away from the planer. Here I have the new roller. There’s a number of parts I’ll need to transfer
from the old roller over to the new, the bushings as well as these felt seals and washers. I’ll start by removing the bushings from either
end, they can simply slide off. You’ll want to inspect the bushing and look
for any wear, or signs of scoring or galling inside the bushing. You’ll also see this on the roller if there
was a problem. You can check to see if the bushings have
play as well. If there’s any slop, you can hear it clicking
side to side, you’d probably want to replace the bushings. Next, I’ll pull off the felt seals and washers,
and I’ll just transfer these right over to the new roller, and then reinstall the bushings. This is ready to go back into the planer. As I installed the roller, you’ll notice that
the bushings are wider in one direction than the other. This wider portion should be up and down to
the planer, so that the bushing fits tightly in the opening. There should be no side to side slop. Now I can re-secure the roller. You’ll notice on the retaining brackets that
one bracket has elongated holes and the other does not. The elongated hole should be on the side opposite
of the sprockets and chains, so go ahead and install the first bracket on the sprocket
and chain side. [pause 00:06:33]
Mark: As I secure this bracket, I want to make sure that the bushing is pushed up tight
against the edge of the bracket. I’ll just push on the back side of the roller
to make sure that it is. [pause 00:07:19]
Mark: Now I can install the bracket on the other side. Again, this bracket has the elongated screw
holes, so as I install it, I’ll make sure it’s pushed tight against the bushing and
that there’s no play. I’ll hold them in this position as a tighten
it down. Now I can reinstall these sprockets and chains. I’ll start by sliding the spacer bushing onto
the infeed roller. Next, comes the first chain and sprockets. On this one, one of the sprockets has a shorter
hub, both these hubs should go against the casting on the planer. The shorter hub goes on the outfeed roller. I’ll first install the sprocket on the motor,
and then I’ll rotate the outfeed roller until the keyway aligns with the shaft. Now I can install the chain between the outfeed
roller and the infeed roller. Here Here I’ll start by putting the sprocket
over the outfeed roller first, and now rotating the infeed roller until the keyway aligns
with the shaft. Now I can re-secure everything with the retaining
rings. Now I can reinstall the gearbox cover, and
I’ll finish up by reinstalling the side covers. You want to make sure you get the pointer
in front of the scale. That’s how you can replace the roller in your
planer. Advertisement: Be sure to check back often

    Thanks for this video as my roller is beginning to slip. I wanted to know if the rollers are OEM quality? If they are I will order the parts from your store. BTW, don't you have to lubricate the bushings? Rama

    Any chance you can do a video on replacing the armature in a DeWalt 733 bench to planer

    Does anyone know if there is a video for replacing rollers on a DW735?
