Is the balance shaft chain idler sprocket needed?

I have only 1, and the torx screw stripped. Is it needed to be there if you plan on deleting the chain anyways? Does it have anything to do with oil pressure?

The balance chain sprocket that goes on the crankshaft is needed to keep spacing correct for timing chain gear and all that. You have to leave it behind the crankshaft timing gear. The alignment will be off if you remove it.

John i think he might be referring to the idler one above that. it's a small one like the ones connected to the balance shafts. But John is right, you do need to keep the one on the crank to take up that space.

Oh, ok, well you need to leave the shafts in of course to keep oil pressure up, but when running no balance chain the idler one can come off, just need the crankshaft balance gear for proper spacing.
