2 question about the LER engine

Guys, good morning.

Was looking at this pictures and I was wondering what does the toothed wheel pointed with the red line, is for?

Are this the balance shafts?

Yes they are the balancer shafts, I'm pretty sure that the toothed wheel is what drives them. The above is a ZLET though not an LER, but the mechanics are the same.

The LEH doesn't have balancer shafts.

hey Scotty boy! thanks for the input!

how did you know it was a LET and not a LER???


Are the balance shafts too necessary for smoothing the engine????

Thanks, have a nice day!!!
