Unscrewing Collet?!

[nosreme722]

Ok, i cant even get the collet off the stock MG motor?!

I have an allen wrench that fits it nearly perfectly but slips when i try to turn it.. Ive tried heating it with the soldering gun, nothing.

Anybody know what size the wrench is suppose to be exactly? US standards or Metric? I have all my MG upgrades in and ready to go and no collet connecter..

They are the same as the blackjack collets. It's a metric set screw, M3. You need to use a 1.5mm allen key. If it's already stripped, it's gonna be a pain to get it out, because there's not much bite in a 1.5mm allen key. If it is stripped, do you have access to a set of easy outs? The smallest one in a typical set will bite in and get it out.

easy outs? what are those?
it will either be 1.5mm or 1/16", those are the standard sizes, although i've come across 1/32, 3/32, and 5/64

If its stripped enough, sometimes you can force the next size up Allen driver in and get it out. Sometimes heat helps with this method too.

Easy outs, or screw extractors, are tools used to remove stripped out bolts. Basically it's a reverse thread spiral. You lightly tap it into the stripped hole, then as you go to unscrew the screw, the spiral digs deeper into the stripped socket. It bites, and you can remove the stripped screw.

And if it's the stock collet, it is M3, so you need 1.5mm. Other companies may be other sizes, but that's what the stock one is.

Alright thanks guys, ill try a 1.5mm M3 allen key and go from there. Thanks again!

1.5mm is the allen key. M3x0.5 is the thread size and pitch of the set screw that's in there.

The set screw is loc-tited so I needed to pull the motor and heat the collet and replace the allen screw (as I also spun the allen key).

[nosreme722]

Ok so just the 1.5mm allen key by itself didn't work. Now to try some heat

Might also try another 1.5 Allen as I've stripped quite a few cheap one a nice hardened one might be a little harder it's often the tool

lol, yup, there's a reason a good quality wrench is more than double the cost of a standard quality wrench.

I bought a set of Allen that have handles at lhs they were 30$ and at frye electronics were 15$ fyi

Trim off the rounded end of allen wrench so it will grip screw better. You may be able to loktite the allen wrench to allen screw (allow the loktite to cure overnight before loosening)

Great tip detox my next recommendation would be to cut a groove on the collet and setscrew and use a small flathead screw driver but that's a last ditch effort to save the motor before drilling it out

I've tried this method and have found it to rarely work for me (usually bends or breaks off exterior of slit). Much better is to use a torx tip. Apply heat first, then lightly tap the tip in. It will bite and come right out.
