Probably best to have a complete CLA done on it while you are at it. A company that has a good reputation and is not over priced is Essex Camera in NJ. You can contact them at

Something that I have recently found out is that you can have a camera CLA in a way that takes into consideration how much use it will receive. For professional use, typical amateur use, or a collectable.
Collectables should not be lubricated, they are likely to only have a few rolls run through them, and then set on a shelf for years and years where the lubes would just gum up again.
For amateur use they should be lightly lubed, as they will only be used for a few hundred rolls of film and will go a long time between CLA's.
Professional use, the camera with have thousands of rolls of film run through it between frequent CLA's, And therefore, should be more heavily lubricated, with more expensive lubricants.
However, any decent CLA should include adjusting hte rangefinder.
