Armature Bearing

REMOVAL

NOTE: Ball bearings that are removed from the armature must be replaced with new bearings. The removal procedure causes internal damage to the bearings.

1. Remove the armature bearings (1,3) and the armature (2) if replacing the armature and the bearings is necessary.
2. Use a suitable bearing puller in order to remove the commutator end or the drive end bearings from the armature assembly.

INSTALLATION
1. Use a tube that bears only on the bearing inner race in order to install the new commutator end and/or the drive end bearings to the armature assembly.
2. Press on the bearing until the inner race bottoms out against the shoulder of the armature shaft.
3. Install the armature and armature bearings.
