Removing the Armature
1. Remove the belt
Remove the screw that secures the belt cover. Set the cover aside.
Then work the belt off the pulleys. You can read our article on removing a DW708 miter saw belt for additional help on this process.
2. Remove the brushes
Now unscrew and remove the saw's brushes.
3. Remove the motor end cap
Remove the two screws that secure the motor end cap to the saw. Set it aside.
4. Remove the dust bag bracket
The dust bag bracket sits in the way of the motor housing, so you will need to remove it. Remove one screw and loosen the other to slide it away from the saw.
5. Remove the motor housing screws
Remove the four screws that hold the motor housing to the motor mount bracket.
6. Remove the motor housing
Now you can carefully slide the motor housing away from the saw to gain access to the armature.
7. Remove the armature
Use a hammer--the ball end of a ball-peen hammer works best here--to tap on the back of the spindle to free the armature from the housing.
Then carefully slide the armature out of the housing.
Installing the new Armature
When you go to install the armature, be very careful of the fan. This is not sold as an individual part, and damaging it will require you to purchase a new armature.
If you need to remove the larger bearing from the armature, check out our article on removing a DeWalt armature bearing.
1. Tap the armature into the housing
Slide the armature into place in the housing.
Then seat the bearing by tapping it with your hammer. Be sure to only tap the screw on the end of the shaft--not the shaft itself.
2. Mount the motor housing
Now set the motor housing into place and tighten the four screws.
3. Install the motor end cap
Position the motor end cap and tighten the two screws.
4. Install the brushes
Install the two brushes back into your saw.
5. Secure the dust bag bracket
Slide the dust bag bracket back into place, then tighten the two screws.
6. Attach the belt
Roll the belt onto the drive pulleys.
7. Secure the belt cover
Secure the cover to finalize the repair.

And that's how you can replace the armature in your DeWalt DW708 miter saw. This repair should only take about 20 minutes and is a good one to know since many other repairs can require you to remove the armature.
