Waterproofing your Ametek Generator

First section covers Easter Egg method.
Don't laugh it works.

Second section below break line covers bicycle tube method

Again this is just a way that I have done it, it does not mean it is the only way.

In this section I will cover the simple "cheap" way I have found to waterproof your Ametek generator.
This is very Hi-Tec so read carefully. ;) HA

Easter Egg Method

To do this, you need 1 of those goofy plastic Easter Eggs, any color you want, it does not make a difference.
some silicone, and a small screw driver or a piece of wire to heat up.

Here we go.
Your Ametek motor has a seem, all the way down one side, that goes on the bottom to keep water from running in the case.

Your egg needs to be taken apart.  You have the longer front section, and the fatter back section.
Take a look at your motor, some have a shaft out the back, some don't.  If you do not have the shaft you do not need to melt ANY holes for this end.  Just skip down to "Lets put this piece on"

If you have a shaft that goes out the back that is longer than the fat end of the egg, melt out the center of the fat end with your screw driver or wire.  I heat them up over the stove and then slowly melt the hole.
DO NOT try to drill this hole it will break I don't care who you are.  I've tried it.

Try to make the hole so the egg will just barely go over the back shaft.
Tight is just fine, it will wear in real quick and make a nice seal in just a couple of hours of run time.

Now that your egg slides over the back shaft nice and snug you need to put a small hole back from the edge about 1/4 inch back.  Just a little hole like 1/8" or so.
NOT on the end you just made the hole.

Lets put this piece on.
Lay your Ametek generator with the seem facing up.
Put a nice bead of silicone on the edge of the egg and place it on the back side of the generator, with the little hole facing up to line up with the seem. (if your shaft is short you do not have this little hole).

Let it set up while we make the front cover.

Now you should have left over, the long side of the egg.  

Carefully melt a hole in this piece to fit over the front shaft.  Remember snug if fine it will wear in.

Now make a little 1/8" hole back from the edge of the egg about 1/4" NOT on the end you just made the hole. 

Now lets put this piece on the same way with a nice bead of silicone.
Push it in place with the little hole lining up with the generator seem.

Let it sit for a couple of hours till the silicone is set up.

Now get your fingers nice and gooped up with silicone and coat the entire egg piece both front and back EXCEPT the little hole.  This will protect the egg from the elements and make a solid cover.
You can stop about 1/8" from the shaft itself.

When you get ready to mount your generator to the Yaw mount you then put a thin coat over the front and back seem of the ends of the generator and any unused holes you may have.

What you just made is a front and back waterproof cap for your generator.  Any water that manages to get past the rotor hub along the shaft and into the egg area will run down and out the hole in the bottom of the egg.
Cool huh.

In this case gravity is our friend since it will not allow the water to run up hill and into our bearings.

I told you it was Hi Tec. ;)

Bicycle Tube Method

Grab any old bicycle tube and cut a piece off 4 inches long.
Split it in half down the seem.
Cut a round hole in the center just a little over 1/2".
Get 4 screws that fit the holes on your Ametek motor.
Put some grease around your shaft at the bearing.
Stretch you rubber hole over the shaft and push it down to the motor.
Raise the edge and put a bead of silicone around the center about 1 inch from where the bearing is.
Now when you hold the rubber out flat it should touch all 4 holes.
Take a knife and pop a hole where the screw holes are and insert the screws.
Trim off excess rubber to make it look neat

Repeat for the other end.

You're done.
