I hate shimming. I think I'll just buy modify gears,

I need a bushing with a thin flange, but I don't have any and I don't want to order a whole set...

If I were to use no shims on the top of the bevel, it makes a weird grindy sound. (I think because it's rubbing on the bushing?)

I also had to swap out the stock gears for an Element sector and JG spur. The stock gears had short shafts (lawl..), not enough room to shim them well. (even though the bushings are flush with the gearbox shell)

@Stealthmaster15 I had a few similar problems. But I have an updated version for this shimming method, stay tuned. With this method you could possibly end up with the bevel gear too high.

Ya i agree with rpdiesel175 this video is way more helpfull than most I'm also doing my first gearbox swap first one was cracked after 6 years of abouse lots of dry fireing (JG strong) only problem and normal O ring wear perfect gears ext but now its time for upgrades went from 6mm bushings to 7mm bearings for a stronger m120 spring metal hop up reenforced 7mm gearbox are theses good starts not lookin for speed right now just power and distance acuracy barrel will be next but have to get paid

Great video i have to shim a systema for the first time . All the videos start with setting the gears low it does make more since to start the way you said thanks for your knowledge.

Do modify gears have to be shimmed?

@kalashnikob1

I sanded down the face off the bushing more, so I think I'll have enough room. The main problem I was having is that the bevel would be tilted when the motor cage was mounted. To be on the safe side, I closed gearbox shell and then mounted the motor cage (to be sure the cage wasn't sitting funny) and I noticed the bevel leans a bit.

I'll definitely wait though, I don't want to keep opening this thing up.

On the positive side, the spur and sector are shimmed beautifully :D
