Most common repair for this saw 1) remove blade & blade housing guard plate 2) You will find 2 allen head screws holding the elevating screw bracket This will allow you to move the gears apart to replace Remove the small retaining ring and slide the gear off (be careful not to lose the woodruff key when you slide the gear off) Typically we find that the 2 rods (elevating shafts) are bent and this causes the resistance that strips the gears out - I always replace the 2 rods and the elevating screw when replacing the gears - you already have it apart and the parts are inexpensive.

The armature is bad. A new armature is about the same cost as a new saw. Buy a Milwaukee next time.

Before you attempt any of this I would recommend going to Dewaltservicenet.com and see what the inside of this tool looks like.

If there is a Service Center near you they have a Max repair rate that they will fix anything on this saw at a preset firm price and if it is less that is what they would charge.

Depends on which machine

If the motor body has two large screws on the outside, then you can remove them and install new brush set. If there isn't, then you have to take the motor apart and install them. Try to look up the saw and get a parts break-down picture or drawing first.
