Narrative:
On apr/xa/00 I changed #3 forward main landing gear tire on aircraft xyz (B767). When a fellow mechanic and I removed the old wheel and tire assembly, the rear spacer for the wheel stuck to the wheel. When we installed the new wheel and tire assembly we forgot to install the rear spacer. We used the maintenance manual but did not carefully read it thoroughly. When the aircraft taxied out the crew noticed the temperature gauge for that wheel was too hot. Maintenance mechanic had to go out to the runway to change the wheel and tire assembly. It was discovered during the tire change that the rear spacer was not installed. The flight took a 3 hour delay. No aircraft damage was noted.
