Screeching Gearbox
25 April, 2010, 17:02
Hi folks,
My G&P M4 variant g/box started screeching when i was using it a few weeks back so i decided to take the gun apart and have a look.
I found that the motor bevel gear has become damaged and there are quite a few teeth that have some damage. I opened up the gearbox and everything looks ok in there.
Can anyone tell me why this problem may have arisen? I have tried a G&G motor in the gun as well and it still makes a similar noise. The gun still operates and fires, but it just has the annoying screeching sound and i fear i will do more damage if i continue to use it like it is.
Does anyone know what may have caused this?
Cheers,
JB

Re: Screeching Gearbox
Chances are the motor height was very badly adjusted. The general rules goes with:
Too loose (far from gearbox) gives a high pitched screech.
Too tight (close to gearbox) gives a low grind and ROF slow.
Best thing to do, replace your beve gear, readjust your motor height. If it still screeches, have a look at reshimming and cleaning your gearbox.

Re: Screeching Gearbox
I had the exact same problem on my BoyI SCAR last week. 1 turn of the adjustment screw on the bottom of the pistol grip and now its perfect again.
Hope this helps

Re: Screeching Gearbox
um do you mean the gear thats on the motor shaft? i thought that was a pinion gear and the bevel is the one that it meshes with, or have i been getting it wrong for ages? :p

Re: Screeching Gearbox
No you're correct. The pinion gear is the small one on the motor shaft, then it's bevel, spur and sector in ascending order.
