Waring Pro Blender is leaking and blade assembly is loose
I know this is an old, old post, but I could not find a solution anywhere, so hopefully this will help someone. We have a model 51BL25, similar to scottman55's blender, and it had the same problem. There are two separate nuts in the blade assembly. One holds the blade on, and the other holds the seal tight. When the latter gets loose, the blender shakes and leaks.
To fix it, first you have to remove the top nut holding the blade on. I had to get in there with pliers, but a ratchet with an extension would be perfect. This nut is right-handed ("normal"). Once that nut is loose, you can remove the nut and the blade. You will also want to remove the washer immediately under the blade (take note of which side goes up).
Now, you can pull the whole axle out by the wheel on bottom of the blender. This exposes a really thin, flat nut. In my case, this nut had come completely off, so nothing was really holding the seal together at all. Again, make sure you remember which direction the nut goes -- it is not quite symmetrical. That nut is what comes loose when the blender starts leaking. By the way, it is a left-handed nut, so it screws on counter-clockwise ("backwards"). Screw it in tight, then put the rest of the blade assembly back together, and your done. If you have the right tools, it should take only maybe 5 minutes.
Depending on your problem/model, this may or may not solve your problem. Hope it helps!
