G&g combat machine internal help

[GingerBreadMan]

My combat machines gearbox stopped and someone told me that it had probably locked. I took it to airsoft zone and they said that the piston and/or gear were partially stripped and it would cost me about 50 to replace them at minimum. So I want to do it myself and want to know what gears and piston to get if I need them and where to get them.

Ak2m4.co.UK shs 18:1 super shooter, shs or lonex piston. Standard v2 gearbox parts.

Great thanks, would these also perform better than the stock gears and piston

[ak2m4]

It will do mate, as long as you fit them properly of course. Plenty of videos out there to help along the way :-)

Thanks for the advice, would the gears need grease, if so what grease do I get?

Also what is the difference between the teeth?

For example this one says 7 teeth http://www.ak2m4.co.uk/internal-parts/pistons-heads/shs-piston-7-teeth-super-shooter, but this one says 3 http://www.ak2m4.co.uk/internal-parts/pistons-heads/shs-piston-3-teeth

[ak2m4]

Teeth generally are either steel/metal or nylon/plastic. You'll find the first tooth generally always metal since this tooth takes most of the strain when pulling back a piston. Full metal are generally a little more expensive but it all comes down to what type of gearbox your going for. Generally for a standard replacement a 1 tooth piston is fine like this one: http://www.ak2m4.co.uk/internal-parts/pistons-heads/shs-piston-1-tooth

 

You'll definitely need some grease, you can pick up some from general DIY shops or I do sell some in small tubes http://www.ak2m4.co.uk/index.php?route=product/search&search=grease

 

Hope that helps a little....

Wow thanks for the help and it I need anything I will order it from you. As the gears would need grease I guess the piston would too?

[ak2m4]

Yeah mate, generally the same grease works well. As with the Gears any good performing grease for mechanical parts is fine. Not quite sure what products like B&Q sell these days but I remember years ago buying a huge can of white lithium grease - was expensive but lasted ages. Some others may have a different idea as to what brand/product works best.
