Oster clippers have two screws retaining the hinge assembly make sure that these are tight the can come loose, also check that the hinge assembly has not lifted away from the body of the clipper, there are two brass inserts which the hinge assembly screws into, they part of the molding occasionally they can pull out causing bad vibrations and poor clipping.
If this is the case you will require a new main body which is a little more technical to replace.

the oster clippers are usually mounted with spring tab to remove blade.Should be no reassembling. If there is, it should be a couple of screws that you screw in

The flange on the front bearing should face away from the fan blade (and protrude slightly up through the hole in the case toward the bakelite gear area), and the flange on the back bearing should face away from the windings (toward the switch area of the case). The felt pads around the bearing should be thoroughly soaked in oil before you put them back in, although the blade end bearing is oiled through the small oil port (the small chrome circular port near the air slots).

If the nylon lever (the tab that moves the blade back and forth) is not moving with the blade off, or only moving sometimes, chances are that you have a stripped bakelite gear. Take the two screws out of the cover plate and remove it. Remove the lever (the nylon part that moves the blade) Remove the link (the metal part that the lever connects with). Remove the bakelite gear (the part that the link fits down over). You should then be able to see if the teeth are chewed or worn off to the point that the armature gear will not turn the bakelite gear. If that is the case, replace the gear. Amazon carries both single speed and 2 speed gears under Oster A5 clipper parts. All these parts should have a light coat, where they move, of lithium grease, and the two pads (one on each side of the lever) should be oiled. You might also check the condition of your brushes (under the caps on each side of the clipper. Take cap off, remove cover from brush, remove spring and brush to see how worn they are).
Good luck.

If the clippers are new, it is not likely that the problem is internal. Sometimes, when the blade is put on the clipper, it needs an extra little push to clip firmly behind the blade catch (you can hear a little click). Try that.

There is a small gun-metal colored bar at the very rear, just below the back of the blade when it is only the clipper. It pushes inward, in the direction of the blade. Push it firmly in and pull up on the teeth of the blade. It should pop upward. You can then remove the blade from the tongue that it sits upon. When you want to put it back, slide the blade back on the tongue, then, WITH THE MOTOR TURNED ON, push the blade down to its seated position. It will click into place.
If you have taken the blade off and the tongue has for some reason flipped back against the head, slide a screwdriver blade behind it and flip it back out so you can slide the blade back on it.
Good luck

This is for Clees534, with whom I have some sympathy. Terms regarding devices are all too often assumed as understood. For most purposes, these are what you have to know for the A5 Oster. 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). That gear is turned by the armature gear of the motor (which is where things get much too involved to cover here, but from that point on the device very rarely has problems). The lever, the link, and the gear can all quite simply be replaced. They are available quite inexpensively at Amazon under Oster A5 Clipper parts (note that the one speed and the two speed take different bakelite gears, but the lever and the link are the same). If you were to replace parts such as these, remember that a good white lithium grease is recommended in light application for the gear and the shafts (lever and gear shafts and armature gear). Also, the 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 simple way to tell if you need to replace parts is to grip the blade end of the lever while all parts are in place and try to move it back and forth, as though it were running the blade. If there is any more than the slightest movement, replace the lever (replace that anyway if the part that contacts the blade is rounded off) link and gear.

So, hope this makes things more understandable. Good luck.

If the power lever (the tab that moves the blade back and forth) is not moving with the blade off, chances are that you have a stripped bakelite gear. Take the two screws out of the cover plate and remove it. Remove the lever. Remove the link (the metal part that the lever connects with). Remove the bakelite gear (the part that the link fits down over). You should then be able to see if the teeth are chewed or worn off to the point that the armature gear will not turn the bakelite gear. If that is the case, replace the gear. Amazon carries both single speed and 2 speed gears under Oster A5 clipper parts.
Good luck.

Your armature feed threads are most likely worn. This will continue to wear gears out unless the armature is replaced. Any Oster factory service center such as ourselves should be able to help. John, Shavers World. 313-534-0736

start the clippers then slide the blade onto the tongue of the hinge assembly , now push the blade into the clipper don't be afraid sometimes they can be tight from new,
Just make sure the two screws either side of the hinge are tight.
