Fix K-9

 is a quest in Fallout 2.

Background
Raul, the vertibird mechanic, has the motivator that needs K-9 to get back to operative mode. Dr. Schreber removed K-9's ability to move when, during the experiments, K-9 disapproved of the doctor's sadistic methods and bit him. This information can be obtained from Cookie (the base cook), the doctor, or K-9 itself. One of the lockers in the vertibird hangar contains the required motor.

If you tell Quincy in the North-East hangar that Raul (the mechanic guarding the repair parts in the Vertibird hangar) sent you for the plans, there will be a dialogue option for you to tell Raul that Quincy wants to see him, whereupon he walks off to beat him up, leaving you free to retrieve the K-9 motivator.

Navarro Sub-floor 1
The laboratory room is soundproof, so you can close the door and kill the sadistic doctor. Now you can talk with the cybernetic dog, and use the part on it to get it fully functional.

Note: This is the only NPC that can roam the base with you without wearing a Power Armor. He can also help you in combat with the deathclaw, if you so chose to go rampaging.
