How to Fix a BE SM8 Black Widow NON-Working Rifle From ShortyUSA

Update 11/9/2011: Been awhile but I have some news, ShortyUSA has run out of Black Widow's for quite a long time now. The gearbox is not strong enough to support stronger springs and powerful motors. I recommend getting an entirely new gearbox if you wish to upgrade. This is instructable may not apply to everyone who bought a broken Black Widow from Shorty, you may have to buy a new o-ring depending on the problem.

BE means Both Elephant which is an airsoft company in China.

Add a Teacher Note to share how you incorporated it into your lesson.

Step 1: Getting Ready

You can buy these guns for only $10! Shorty USA wants to get rid of them because they are all broken. But what I found out was that the o-ring was placed in the wrong spot.
Things Needed:

2)Steel Rod
3)Drill bit

Update 11/9/2011: Goggles
gloves (optional)
pliers (optional)

Step 2: Taking the Cover Off

This is where you need one of those choices: 1, 2, or 3.
1. Cut the chopsticks thin enough to fit through the holes of pins (the things that hold the gun together). Put the chopstick on top of the pin and hammer it out. Refer to the instruction manual to take it apart.
2. Use the steel rod and push down onto the pins until they come out. Refer to the instruction manual to take it apart.
3. Same thing as number 2. Push down and refer to the instruction manual.

Use the screwdriver to take off the cap of the handle. Refer to picture for reference.

Step 3: Opening the Gearbox

Now this is probably the hardest part. Make sure that you don't lose any parts. And yes it is normal if it is very greasy. The smell is also caused by this grease. You can wipe some off if its too unbearable. Use the screwdriver to take out the screws.

Step 4: Moving the O-ring Back and Reassembly

Take the black tube out and pull the beige tube out of the black one. Now look at the black rubber circle thing. Pull it over the notch, the one behind it. If yours is really malformed then buy a new one. Make sure everything is in place. Refer to diagram link. After that reassemble everything and wipe off excess grease.

    Do you have any pictures of the trigger section from the inside? I took mine apart, and the entire little mechanism exploded out towards me. I have all of the pieces, but I dont know where to put them! Thanks

    On step 5, click the link and it should show a diagram of the gearbox of this airsoft gun. It also shows the trigger mechanism.

    I put it back together, but i dont know where two of the springs go, so the trigger gets stuck, i need to see it like it is in one of the pictures on this step, but the pliers are blocking the view. Its good for now, its just the trigger gets stuck sometimes.

    I'd been considering doing this for a while, but I didn't want to spend the money. If you know anything about airsoft guns, do you think this could reliably take an M120 spring, a higher end gearbox, motor, etc. and get a good gun for ~$150?

    Its only $10. And it comes with a battery ($20 value), and a speedloader! If you don't buy this then you should keep saving your money to get a gun from Classic Army, ICS, or Tokyo Marui. I don't know if shorty usa has any more left though :P
