This article explains one backup method for removing armature bearings when a bearing puller isn't available.
Armature bearings need to be removed from power tool armatures for a variety of repairs. Most of the time, the best way to remove an armature bearing is with a specialized tool repair tool called a bearing puller, but a good bearing puller isn't always available.
Also, manufacturers sometimes don't leave enough space underneath the armature bearing to properly affix a puller. In either case, having a backup method for getting that bearing puller off is a good idea.
We explain some simple steps below for how to remove armature bearings using a vise, a useful trick when other methods aren't an option.
A small vise is usually best for this repair, because the bearing will need to protrude past the length of the vise without the armature fan getting crushed at the other end of the armature.
You will also need two small pry bars or flat head screwdrivers.
1. Position the armature body securely in the vise so that its bearing sticks out one end. Make certain not to damage the armature fan in the vise.
2. Wedge your pry bars or screwdrivers carefully behind the armature bearing.
3. Apply equal pressure to both sides of the bearing, and leverage it off of the armature.
