Narrative:
Overhead the hbk NDB, accepted a new clearance from anc center: present direct laire direct to VOR direct fly planned routing. Passing laire continued in accordance with original flight plan routing laire-bka-ann-hanry-duggs-yzt-tou. We deviated from the revised clearance. Queried by vancouver center 42 NM northwest ann VOR. We then proceeded direct tou VOR. To the best of my knowledge, our clearance deviation caused no other conflicts. I estimate our ground track was some 22 NM east of what center wanted us to fly in the revised clearance. We flew for 18 mins before center queried us. PNF failed to completely enter new clearance into FMC. PF did not see the mistake. Debriefed amongst the crew.
