Narrative:

While changing right nose tire; the spacer got stuck on the bearing on the removed tire and I did not notice that the spacer was missing from the axle. The tire was installed on the aircraft without the spacer for the new tire. The spacer was found to be missing. Aircraft nose gear was inspected; axle spacer was re-installed and aircraft was returned to service without incident. I was assigned a callout; plus #3 service check. With the items found during the check; I had a heavy workload that evening; which required many extra man hours. Due to lack of man power it caused me to be preoccupied and fatigued at various times in the evening.
