Do those inner pieces in a 4x4 serve any purpose?

I just did a solve and noticed a pop, but carried on regardless, intending to re insert the piece at the end. When I finished i saw that the only thing that had popped was one of those inner mechanism pieces. Certainly strange how it popped out on it's own without the actual cubie popping too.

The point is though that I now have 2 of those pieces missing with no ill effects as far as I can tell. This is on a MoYu WeiSu. What purpose do they serve if it's perfectly fine without it?
 
Two are missing, but take out all of these, and the cube will not be able to move if you ever assemble it without them.
 
The shengshou 4x4, moyu weisu, aosu, and v and x-cube are basically a 5x5 with the middle layer hidden. The hidden layer are the inner pieces, some of which are bandaged to prevent lock-ups. Without it, the entire thing would wall apart in your hands. I have heard that on the weisu that what you said is common, if only that one piece pops out, you should be able to finish the solve without problem. Aosu, it doesnt Happen, and if on a shengshou, it is usually alongside an explosion.

edit- saw that it is 2 pieces, same thing, works fine. You should order replacement internal pieces if this keeps happening though, because the cube was made to be complete.

You can miss one of the small inner pieces, or two assuming that they are not adjacent, but the puzzle will fall apart if the big ones fall out. Try disassembling the cube and putting back the first two layers to really learn how the pieces in even layered cubes are locked together.
 
Not having the inner pieces is a recipe for an in-comp explosion. I strongly recommend you sort it out asap.

Too late. It appears that while the cube will function perfectly fine with two pieces missing, what would normally be a single pop becomes an explosion.

Nope, those pieces are just there to make the cube harder to reassemble. They have no function whatsoever.
 
Ouch. Was that in comp, or were you lucky enough to deal with it at home?

At home luckily. With previous cubes like eastsheen and Rubik's, missing pieces made it either difficult or impossible to turn, but this time it functioned just as normal, which mislead me into believing there was no point trying to disassemble and reassemble :(

Lol dude you are so out of the loop hahahaha.
 
I just lost one of the small internal pieces in my YJ Yusu. Should I order a new piece, buy a new Yusu, or buy a better 4x4? Is it vital to have it?

If I were you, I'd order a Yuxin or Aosu from wherever you bought the YJ, and ask for an additional replacement inner piece for the YJ.
 
Does anyone know if the Cyclone Boys is any good?
How big an upgrade is it from the Yusu -> Yuxin or Aosu? It's quite a price jump for me
 
i understand what the big internal piece does but what does the small one do?
why cant you have one big one instead of i medium and two small internal pieces?

I guess you don't actually understand the big internal pieces then, and haven't even read this thread.

The CB is really good if you're willing to set it up, but after around 100 solves it's still not better than the Yuxin.

I think the Yuxin will be a great upgrade from the Yusu.
