Guest JinxDuh Posted April 25, 2024 Posted April 25, 2024 Hey guys. Bought a pre owned replica from here a few days ago, changed out the motor as the one it came with was on its last legs and wasn’t cycling properly. Testing it with the pistol grip off, as it cycles a fine blue powdery dust is coming out. It’s an Ares Thompson, and I can’t work out how to get the gearbox out to disassemble it but there was a lot of metal shavings around the gearbox too which is worrying. Any ideas what this mysterious blue powder could be?

Supporters Lozart Posted April 25, 2024 Supporters Posted April 25, 2024 But seriously.... How blue are we talking? Pale, dark, vivid, pastel?
Jamsandwich Posted April 25, 2024 Posted April 25, 2024 Pics would help, but it kinda sounds like thread lock...used as lube...?
Guest JinxDuh Posted April 25, 2024 Posted April 25, 2024 Very pale blue, mixed with metal shavings I’ll put it back together and get it firing again to get “fresh” blue powder And a better example of the colour

Might be coming off an anodised metal piston or something similar.
Guest JinxDuh Posted April 25, 2024 Posted April 25, 2024 Having to drill out one of the screws as it was fully rounded off, to then be able to get the gearbox out. Only time will tell what the mysterious blue powder is! Probably for the best anyway as the pew is missing nearly every screw anyway ? 1 minute ago, Lozart said: Adventurous. I like it! I agree.

Guest JinxDuh Posted April 25, 2024 Posted April 25, 2024 Nothing in the gearbox, so I’m assuming it’s the motor. Possibly copper wires corroded/corroding
Sewdhull Posted April 25, 2024 Posted April 25, 2024 (edited) The only corrosion that's blue I know of is that of copper. But it could be ground up thread lock Edited April 25, 2024 by Sewdhull Lozart 1
Guest JinxDuh Posted April 25, 2024 Posted April 25, 2024 I stuck the motor into my AK, blue dust appeared so the culprit is the old motor. Sadly there’s a screw that’s been glued so had to cut and drill to even get the gearbox out so progress is halted until I can fix the broken piece. Rather disappointed I’ve had to carry out repairs on a gun that was sold as fully working but such is the way of life ?
ak2m4 Posted April 25, 2024 Posted April 25, 2024 What brand motor? 43 minutes ago, JinxDuh said: I stuck the motor into my AK, blue dust appeared so the culprit is the old motor.

Oh I got the impression you were getting the blue stuff from the new motor The blue dust motor was a black no brand one that came with the random AK parts I got from on here a while back. The new motor was out of a Cyma and works fine!
Moderators Jez_Armstrong Posted April 26, 2024 Moderators Posted April 26, 2024 Could the gun have been two tone at one point and the motor grip changed out for a new one still leaving residue on the bottom of the gearbox housing?

I think it may have been used in the Great Smurf Massacre of '02. It's dried smurf blood and evidence of a war crime! gavinkempsell, Shamal and Rogerborg 1 2

No, the old motor is just, well… old. You can see the copper inside starting to oxidise and as it’s working it’s spitting out the dust. New motor is fine
