If you can, remove the variable capacitor and get it ultrasonically-cleaned. This will shift any accretion of dust/grime between the vanes, and also remove the time-hardened grease from the bearings/drive mechanism.

Then, after drying off [an oven set to 85 Centigrade], use a light oil on the bearings/gears and re-fit. You'll be amazed at the improvement in local-oscillator stability!
