How to Clean a Juicer With No Instructions

Friend of mine gave me a veggie juicer to fix. The problem was that it's leaking around the spout. I can see all the gunk on the edges. But with no instructions, how does one take it apart ?

This one is simple enough. Just unscrew and remove the cutting blade. Careful not to cut yourself.

The mounting wheel is hopelessly stuck, and I have no grip ...

All blenders & juicers have left handed screws. I just put back a mounting screw & gave it a few wacks counter clockwise. Sucker came right out.

Now that everything is off, clean everything. If space is available, put them all into a boiling pot of vinegar solutions, then scrub down all the small places with tooth brush ...etc ...

Put everything back in reverse order.
