JG HK416 grating gearbox noise

[clayman]

My Jing Gong just makes a grating noise like grating cogs. Guess somethings jammed inside but cant see any obvious way of stripping it to see.

Any-one know of any manuals / parts diagrams / exploded views or U-tubes etc on a trip down - or any input on what causes this noise and and cures for it?

I had the same gun with same problem, theres a big screw on the bottom of the pistol grip, you need to adjust that, I just don't know which way, Either someone else will know, or you'll just have to test it out.

Yeh, adjust your motor height. (Screw On bottom of pistol grip)

The noise may be because the head of the motor is too far up against the gears or too far down.

If you try changing the motor height to various positions and it is still making the noise you may want to take it to an airsoft store that does repairs and explain your situation
