I like to clean the sintered bushing first and relube with the blue 3 in 1 product, yes (I also polish the armature shaft with very fine wet/dry sandpaper if it shows any discoloration...wet the paper with the oil). Sometimes sintered bushing that old style will have a felt wick that's supposed to be wet with oil as a reserve for the future....don't remember offhand on the G. I go inside a lot of small electric motors.
A bit later on from that era, sintered bushing were impregnated with lube and they wanted you to just replace them. A lot of controversy there....dry lube, wet lube...some say you'll ruin the sintered bushing if you clean it and relube (the modern ones). Unless you know exactly what lube they used, your added lube could gall up the works.
Not something you worry about with a G motor though......just sintered bushing trivia...lol.
Some vac motors will have a foam like seal where the motor sits in....1205 comes to mind. Don't freak over finding OEM foam. The weather seal stuff they sell for doors is an excellent, durable replacement.....find the correct width and sponginess type of the original.
