Tools you may need include, soldering iron and solder, utility knife, putty knife, compressed air, masking tape, safety glasses. The angle grinder with a surface prep disk is optional but does make the job a lot faster.
We have found that the best masking tape is the Ace Hardware General Use Masking Tape, item number 12708 This tape has just the right amount of stickiness and thickness.

Use a utility knife to cut around the surround. Next fold back the cone and de-solder the lead wires from the terminals. Make sure that you remove the solder from the holes in the terminals.
Cut around the spider and remove the assembly.
Keep all debris out of the voice coil gap. Cover the voice coil gap with masking tape.

Cut the gaskets away from the frame. Be careful not to damage the gaskets, you may want to reuse them.
Use a putty knife to remove the what remains of the spider and surround.
You can use a solvent like acetone to soften the adhesive and scrape with the putty knife.

Using the angle grinder here will save you a tremendous amount of time.

After removing all debris, remove the masking tape from the gap. We find it useful to use compressed air to blow out any debris that is in the gap. This is very useful for that voice coil that has come apart in the gap. Blowing compressed air can help to remove the old coil.
Now cut a piece of business card or similar cardstock to the width of your masking tape. Fold the tape over the strip of card, sticky side out. Insert the tape and card in the voice coil gap and run it around to remove all debris from the gap. Look in the gap with a flashlight, make sure no debris is left in the gap. It is very important that no debris remains in the gap.

Test fit your recone kit with the centering shims in place before applying glue. This is the time to make sure every thing fits correctly, before applying the glue.
After testing fitting the kit, apply a bead of glue to the spider and surround mounting surface. Let the glue sit and tack for five minutes.
Position the frame so that the wire terminals are pointing at you and set the kit into place making sure that the lead wires line up with the terminals.
Insert the centering shims. Run some sort of smooth item around the surround so its makes good contact with the glue and frame (a dissembled clothespin works well for this). Use fingers to press the spider onto the frame. Be careful not to push the kit further to one side than the other. Let the glue dry for 8 hours.

Solder the lead wires to the terminals. It is not necessary to insert the wires into the holes but in either case, make sure you have a good solder joint.
Now that the glue has dried, this is the best time to test the repair and make sure everything has been aligned correctly.
Remove the centering shims. Test your speaker. Listen for any excessive rubbing or ticking. In the shop we use a sound generator run through a power amplifier. With this setup we can do a full frequency sweep of the speaker. You can also use a test tone CD or music.

To install the dust cap, first dry fit the dust cap and trace around it with a pencil. This will show you where you need to put the bead of glue. Place a liberal amount of glue directly on the pencil line.

Make a handle for your dust cap with a piece of masking tape about 1-in long. Loop it together sticky side out. Attach it to the center of the dust cap and lower it into the glue. If you think you need more glue on the dust cap, you can place a small bead between the cone and the dust cap as shown. Now place a weight on the dust cap to keep in down into the glue. Do not use too heavy of a weight. You do not want to over stress the spider. Use your best judgment. Let the glue dry for a few hours and you are finished.
