It sounds like you know pretty well what you're doing and mainly just need parts then. I suggest clipperparts.com. They are the kings of clipper parts and very knowledgeable if you need a little extra help
The cover plate is the part with two screws that has the name and other info on it. If you remove the two screws and the plate, you will see a nylon part that moves the blade back and forth--that is the lever. The other end of the lever, with a hole in it, is connected to a metal part called the link. Both parts are easily removed by simply pulling them upward from the device. The bakelite gear is the part that the link sits on (the larger hole in the link). It too can be simply pulled up off the metal shaft that it rides upon (careful not to lose the washer under it). If you don’t have a tube of oster grease, a good white lithium grease is recommended in light application for the gear and the shafts (lever and gear shafts and armature gear and teeth of bakelite gear). Also, the bakelite gear shaft has a hole down its middle and two small holes that lead to the outside of the shaft. The shaft should be filled with grease so that grease can get through those small holes to lubicate the inside of the bakelite bearing. The small pads on each side of the lever (in the case) are oiled, not greased. Oster clippers, by the way, are known for getting pretty warm. Oster blade wash will help with that, as well as oiling the blades.
