Armature removal

[valkokir]

I'm unable to pull the armature out of the plastic case and field coil. With the gearbox disassembled I can pull the armature forward about 3/8" before it meets resistance and won't spin which tells me it's hung up on something (possibly the contact spring #48 above?). I have removed the brush holder. The armature moves forward far enough for the rear armature bearing to be free of its pocket in the plastic case.

Thank you

Hi valkokir,
If you overheated the tool and burned out the armature them most likely you have melted the plastic field housing and that is whats preventing the armature from being removed. If this is the case you'll have to replace both the field and armature. Hope this helps.Good luck.

Thanks Tinker.
Well my description wasn't very good, I suppose. The drill operates great intermittently. The only thing wrong is a broken Switch contact (#74) it occasionally makes good contact and when it does, the drill works great. The contact connection is broken off in the terminal of the field coil and consequently, I need to remove the armature and field coil to repair. I just can't get the thing apart and I can't tell what it's hung up on. Quite frustrating.

Hi Valkolir,
You don't have to burn the motor out to get the field housing hot to melt or distort enough to prevent the armature out .If the armature moves freely around the housing then this is most likely what happened.

You were spot on. I managed to pull hard enough to get the armature out and the plastic shielding on the field is distorted, preventing it from coming out easily.
Thank you very much for the help
