Keyless Chuck problem

[Hesstondriver]

Could any one explain how they work , and more specifically how I in undo one that it fully closed but seized?!

I usually clamp as tight as possible without damaging plastic, in a protected vice and reverse drill to hopefully undo chuck.

Firstly, have you tried putting the base of the drill (the motor end) on a hard surface, then with the chuck in the air, tap the three drill bit grips downwards (gently - not like an animal) flat across the top of all 3, then operate the chuck? This can sometimes free up the restriction to allow you to operate the chuck.
If that doesn't work, I would try a pair of pump pliers on the base of the black section of the chuck to hold it whilst using a second pair of pump pliers to hold the knurled metal section whilst rotating the chuck (you can use a piece of rag on each of the grips to reduce the grip biting in).
Once opened - two choices then, remove the chuck fully and clean parts or replace the chuck. It may simply be that there is dirt in the chuck making it bind and a good blow out and cleaning with WW40 etc returns it to usable operation..

I did the hammer trick to mine recently but I've lost the zippy cam tightening now.

thank you all , i gave it a couple of sharp taps , bathed it in wd40 and just used my baby stilson very gently and it came free, ive just given it a good blow out wit the air line and more wd40. i can only assume it was dry and a bit of dirt caused it to seize up. incredible what binding power it has !

They do this if brick dust for example gets into the mechanism. It is an often overlooked part of preventative maintenance which I try to do every couple of months now after being caught out. Glad you got it sorted

What do you mean by zippy cam tightening, are you referring to the clicking noise as it ratches up?

yes, doesn't click, usually get three or four clicks as it winds down.......no more though. I haven't confessed I haven't worked on it since so it might loosen up with work.

You can strip them down to give a thorough clean out and see what is happening, as it could be dirt in the mech.

If your getting bother take the chuck off ,throw in bin and put a new one on ,get a steel one not plastic ,far better

i have an aeg drill like that, nice drill to handle but my one overheats and cuts out after 45-60 seconds work. almost impossible to contact them for warranty and now the warranty is out so saved myself a lot of grief and bought a dewalt. i should have bought a milwaukee but have other dewalt tools with the same batteries.
