Narrative:

On oct/xa/99, my partner and I changed a B767 #1 main tire and rim assembly that was deferred from south america to be done prior to departure. It was XA15, still dark out, and clear WX, 53 degree temperature. We changed the tire and wheel assembly according to maintenance manual. No difficulty in removing or installing the assembly. We finished at XA40. The aircraft took off and reported a brake temperature rise on that axle assembly or that wheel assembly. Aircraft arrived at xyz and a&P's removed tire and wheel assembly to find rear axle spacer missing. They replaced the spacer, did an axle damage check inspection, found no damage and replaced the tire and wheel assembly. Aircraft incurred a delay at abc. In our procedure of changing the tire and wheel assembly, the rear spacer had been stuck to the old wheel assembly we removed. We installed new wheel without the rear spacer.
