DeWALT Drill Repair – Replacing the Thrust Bearing (DeWALT Part # 091644-00)


“Power tools use many bearings to allow various
components to rotate. Over time a bearing will wear and begin to
fail. A bearing that is failing will usually give
warning, often with a squeaking or squealing sound. Replacing a bearing 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 this are easier
than you might think. From lawn machines to cordless drills, kitchen
mixers, outdoor drills. 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 chuck. First I’ll remove the retaining screw. It’s a reverse thread, so I’ll turn it clockwise
to remove it. With the retaining screw removed, now I can
remove the chuck. To do that I’ll take a large Allen wrench
and chuck it inside the chuck. I’ll rotate the Allen wrench around so it’s
sitting just a little above level, then I’ll use a rubber mallet to quickly strike the
Allen wrench. The quick momentum will break the chuck free
from the thread. Now I’ll remove the gearbox assembly from
the motor. Now I’ll remove the spindle and gear. With the gear removed, I can remove the bearing. Notice with the bearing there’s a washer on
either side of it. The second washer is stuck in the grease on
the gear, I’ll remove it with a magnet. Now I can reinstall the gear. I’ll place the gear back into the needle bearing
on the gearbox. Now I can install the new needle bearing. I’ll place one of the flat washers over the
gear spindle, then I’ll install the needle bearing. I’ll press a little of the grease into the
needle bearing then I’ll install the second washer. Now I’ll re-install the gasket. I’ll align it with the pins on the gearbox
and make sure it’s sitting flat all the way around. Now I can reinstall the gearbox to the motor. You may need to rotate the spindle a little
bit to get the gears to align, and I’ll secure it with the screws. Now I’ll reinstall the chuck. I’ll throw the chuck onto the spindle and
I’ll place the Allen wrench back into it. I’ll give the Allen wrench a tap just to make
sure the chuck is tight. I’ll finish up by reinstalling the chuck-retaining
screw. Place it into the chuck and tighten it. Remember it’s a reverse thread, so I’ll tighten
it counterclockwise. That’s how you can install a new thrust bearing
in you power tool. Be sure to check back often for new videos
