Re: Overdrive Governor
Remove the governor again. Get it on your bench and remove the 3 or 4 screws holding the top cover on. The governor was made in two versions, each of which utilized a different centrifugal switching mechanism. From your photos, you have the 4 screw type. Be sure to carefully remove the very thin gasket so that it doesn’t get torn. With the cover off, clean the internal mechanism. We use our ultrasonic cleaner (hot soapy water with vibration) to clean the entire unit. You can also use a Brakleen spray can to clean it out. Use a compressed air nozzle to blow it out. Clean repeatedly until you can turn the gear and shaft easily with your fingers.
While it’s off, clean the brass contacts on the top cover. Reinstall the cover and put the governor back onto the transmission. You can test it again as you did before with the ohmmeter, but that’s not a scientific test for the actual kick in speed. You’ll have to road test the car to confirm that. There’s a fair chance that the cleaning will improve its performance.
