The wire lead to the brush overheated and burned off.
I unscrewed the caps, that hold the brushes in, on my Milwaukee sawzall. I went to pull the brushes out and discovered the burnt wire lead. I ordered new brushes from ereplacementparts. When I received my parts, they weren't the correct ones. It was my fault, because I ordered ones for the wrong model. Called ereplacementparts and got help with ordering the correct brushes.I was reimbursed for the original order and told to just keep those parts. The correct new parts were ordered and within 2 days I received them. The new brushes were an improved version. The original brushes have a thin metal contact and a spacer, with the screw cap ,to make the electrical connection, in the housing. The new brushes, have a thicker and taller electrical contact, on the end of the wire. This required that I leave out the spacer, in order to screw in the brush cap. I believe the original brush burned the wire off, because the cap came loose, allowing the spacer to back out some and create a poor electrical connection between the contact and the housing contact. I will use ereplacementparts again, when the need arises, for repair parts.
Did these repair instructions help you?

Question: Spindle & Tube Replacement

1164279

What type of grease should be used between the tube & spindle? I'm planning replacing both on my unit and it did not seem to have any previously. The spindle is visibly worn at the tube contact points and is heavily scored and even tempered at the front bearing. When I'm using it just doing a few light cuts the gear box gets so hot I can't even hold it.

Hello wattkr,

It is not necessary to remove the boot from the saw to replace the quik-lok blade clamp on the Milwaukee Sawzall. It will make it much easier if you position the blade shaft to the end of the stroke. To replace the blade clamp assembly.
We have also prepared and article and video to aid you in this repair. Here is the link to it.

How to Change the Milwaukee Quik-lok Blade Clamp Assembly.

Hope this helps,

Question: 45 Gear On 6521 Super Sawzall

206benji

Im trying to relapce the 45 ring gear on a 6521. I grabbed the gear w/ pliers and used a wrench to spin the lock nut, but the shaft just rotates with the nut while the gear remains gripped in the pliers.

Thanks, I looked at the diagram and saw the gear assembly is sold as a complete unit and figured I would order that. However, how do I get the old one(s) out?
( I have two that need replacement)

At the other end of the shaft,there is a nut that has to be removed..if you pop out the plastic or rubber insert at the end of the housing you will be able to access..as far as the other gear [on the eccentric] there are detailed removal instructions at link removed..
kind of a pain...:)

yes, I put a wrench on the lock nut at the other end of the shaft and use large channel locks and rubber hose to hold the gear, but the shaft just spins with the nut. grrrrrrrr

Ugh..
I'm not sure but it may be a reverse thread..so try loosing it the other direction..? They are on fairly tight also so you may have to really lean on it...:mad:

use a cordless or electric or pnuematic impact wrench to take the nut off, the torque on the wrench will easily remove the nut
Anybody know how much of the tip of the wobble shaft should stick out at the top after pressing on new gear and it's corresponding disc spring and washer?

Hi Hindenburg,

The last page of the breakdown in the PDF version has repair notes including the specs on pressing the gear onto the shaft. You can find the file at the following link...
