DeWALT Impact Driver Repair – Replacing the Compression Spring (DeWALT Part # N019351)


“The compression spring is part of your impact
drivers chuck assembly. The spring fits over the anvil shaft and applies
tension to draw the chuck collar back after a bit is removed. Over time, the spring can fail. This will allow the collar to move freely
which can cause the driver bit to come loose. Replacing the compression spring is a repair
that you can do yourself and I’m going to show you how. Mark: Hi. I’m Mark Sodja. [music]
Do-it-yourself repairs like this 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 hog ring
from the chuck. The hog ring fits into a groove on the anvil
and secures the chuck together. There’s a spring behind the hog ring so I
want to be careful that I don’t lose all the parts when the hog ring is removed. I’ll use a pick to remove it. Now I can replace the compression spring and
place the plain washer over the top. Now install the hog ring. This is a little challenging because you have
the compression spring trying to push everything away from the anvil. What I’ll do is take a small pair of needle-nose
pliers and use them to compress the spring. You’ll notice that the anvil is dog-eared
and I’ve aligned the plyers with the dog ears on the anvil so I have some room to work around
the spindle. I’ll place the hog ring over the spindle. That’s all it takes to replace the compression
spring in your impact driver. Mark: Be sure to check back often for new
videos and expert advice. If you found this video helpful, give us a
