    IMPORTANT UPDATE!
    This trick only works if the magnet can make contact with the pin you want to remove! Without direct contact, the magnetic pull is not strong enough!

    I came up with this idea recently is response to a thread asking about removing the wheels from Transformers. The usual trick is to use a soldering iron to heat the pin and then use the wheel itself to pull the pin out. Well, I've used this method successfully, AND I've had it backfire and destroy the wheel. This little trick ensures that you will not damage the wheel at all! Here's how it works.

    What You'll Need
    -Transformer with a wheel that needs removed. (This is one from my fodder bin.)
    [​IMG]

    -Soldering Iron. ($10.00 at Walmart.)
    [​IMG]

    -Very strong magnet (This one is out of an old computer hard drive I had.)
    [​IMG]


    How It Works
    1. Heat the pin with your preheated soldering iron for about 30-40 seconds. Be careful not to touch the wheel with the soldering iron or you will melt the plastic!!!
    [​IMG]

    2. Apply the magnet to the pin. You want to move quickly, yet safely to this step so that the pin doesn't cool off too much and thus require reheating.
    [​IMG]
    3. Pull slowly. Go slow. If you go too fast and you'll pull the magnet off of the pin.

    4. Repeat steps 1-3 if necessary until the pin and wheel pull free.
    [​IMG]

    That's it! Simple wheel removal without damaging the wheel in the process!

    I hope this helps everyone!

    Are you asking as someone who already knew this trick, or someone looking for a different method?

    What I've recently done... is have an Ultra strong magnet...
    (dunno where I got thme from but I have 3 which are like 5-7.5cm in diameter)
    attach that to the soldering iron,, flatten the tip of the iron a bit...

    PRESTO!!!

    BE CAREFULL mine will wipe clean your creditcard/phone/camera/Harddrive...
    from almost a bl**dy feet!!!

    EDIT: I tested.. to 3magnet togheter can hold my own WEIGHT!!!! WOW 80+ kilo's

    This couldn't be more timely. I have four wheels that need removed and I was worried I would damage them. You da man!

    The only other trick I know is to heat the pin and then use the wheel itself to pull the pin. But, that is how I messed up the wheels. You may be able to grab the pin with a pair of this needle nosed pliers, but so far, this is the best method I've found.


    Glad people are finding this helpful!

    Nice tip. Speaker magnets from old tape players are also very strong.

    When replacing the wheel, does the pin slide back in and hold, or is it required that the pin is given heat before placement?

    Whenever possible I drive wheel pins out from behind with a pin punch. I sometimes have to drill a small hole to be able to push it out.

    The surrounding plastic will usually tighten and return to its original shape once it cools, or close enough depending on how clean the pin removal goes. You'll need to reapply heat to the pin if you plan to reattach it. However, insertion is usually quicker and easier than removal. You don't need to spend as much time heating it up as you did the first time.

    Great tip, I have to try it sometime.
    One question though, will rare earth magnets suffice?

    So the pins just pop back in with a little heat? That's the one thing that's been stopping me from trying wheel removal.

    They should. Once you have enough heat where the pin begins to wiggle, there should be enough strength there to pull it out.

    Yup. Just make sure to keep your hand nice and steady as you're trying to guide the pin back into the hole or post. Patience is also key as you don't want to force anything.

    I agree with this, and I find it works every time. One key thing to remember is to have a roll of tape to rest the piece with the wheel on. It will absorb the shock of driving out the pin and keep the surface you are using from getting damaged as well.

    I use a 1/16 pin punch, it seems to be the size most pin holes are on transformers toys. I also want to point people to the Radicon tutorials section >> http://www.tfw2005.com/boards/tutorials-how-tos/201900-table-contents.html << where you will find, among many other useful tutorials, pin removal. The magnet method described here is awesome and if I wasn't already happy with my pin punch, i'd def give this a try.
