J. The armature should always be checked for end
play. Armature should turn freely with minimal
end play.
On older models - after the thrust bearing
assembly has been seated properly and proper
amount of spacing washers placed at the rear, there
should only be a perceptible amount of end play to
assure free operation of the armature.
If there is too much end play, add another thin
washer.
To do this, remove the bearing bracket and add
the washer to the armature shaft, then reassemble
the bearing bracket into the gear case-motor
housing.
