Angle Grinder Repair – Replacing the Power Cord (DeWALT Part # 330072-98)


Hi, I’m Mark from ereplacementparts.com. In this video, I’m going to show you how to
replace the cord on a DeWALT grinder. Power cords take a lot of abuse and eventually
they will need to be replaced. Common problems with power cords are cuts
in the insulation that go down to bare wires. Another common problem is kinks in the cord. This especially happens up where the cord
meets the plug. Power cords are easy to replace and we’re
going to show you how. Power cords, as well as many other parts,
can be found on our website. Let’s get started.We’ll begin by removing
the side cover at the rear of the grinder. It’s secured with five screws. Now remove the paddle and the lock button
and separate the other half of the rear housing from the rest of the grinder. Now remove the two screws that hold the cord
clamp in place. I can pull away the cord and the switch from
the housing. Next, I’ll remove the cord from the switch. It’s secured with a couple of screws. There may be different types of connectors
used. Now I can install our new cord.First, I need
to prep the cord to get ready for the new connectors. We’ll need to crimp these connectors onto
the end of the cord. What I’m doing at this point is just measuring
the length of the wires. I’ll line them up the same with the old wires
and then cut them to length. If anything, I want them slightly longer. You want to make sure you don’t cut them too
short. Don’t forget to include the length of the
wire that’s inside of the terminal. With the wires cut to length now, I can go
ahead and strip back the ends. I will strip back about a quarter of an inch,
and I’ll just give the wires a twist.Now we need to put some new terminal ends on the
wires. There is a number of different types of terminals
you can use. I’m using these ring types. There’s also spade types that are open on
the end. You can even use what I would call a bullet
type. The bullet type just crimps around the wire
and makes it stiff so you can insert it back into the switch. With the ring type or the spade type, you’ll
just place the terminal over the bare part of the wire and then crimp it using a crimping
tool. The last thing I want to do to get our new
cord ready is to swap the strain relief from the old cord to the new. Don’t forget this step, or you’ll have to
take everything back apart.Now I’ll install the cord back onto the switch. Now I’ll install the switch back into the
housing. I’ll also place the cord and the string relief
back into the housing. I want to take a moment and tuck the wires
down and out of the way so they don’t get pinched when we reassemble the rest of the
grinder. Once everything is in place, I’ll secure the
cord and switch with the cord clamp. Now I can install the rear housing back to
the rest of the grinder. I need to make sure that I have all the wires
tucked out of the way so they don’t get pinched.This lower wire runs behind the stud, it then goes
down in the opening for the paddle switch. Now I can reinstall the lock button. You’ll notice that there’s a tab on one side
of the lock button. That should go towards the armature, followed
by the paddle. Now we can finish up by reinstalling the other
half of the rear housing. As I do this, I want to make sure the posts
on the switch and on the lock button all line up properly with the housing. Once I get it in place, I’ll just test everything
real quick to make sure it’s right. That looks good, so I can resecure the screws.That’s
all it takes to replace the cord on a DeWALT grinder. If you found this video helpful, be sure to
