When cleaning the secondary does it matter how the two faces bolt back together? Where the balancing holes are does it effect the clutch performance?

I believe the two sheaves are balanced individually so it does not matter! Obviously there is a front and back one!

Any more comments on this topic or is agreed that 2 halves don’t need to be be marked for reassembly? Obviously I’m asking because i forgot to mark mine when taking apart. Would love a quick reply or 2 as I’m just about to put mine back together.

The sheaves are in-fact balanced separately, you're good to go, just throw it back together.

Thanks Stubbs. That’s the answer I was hoping for.

LOL, I had heard the same back when I had my 08 Apex secondary apart and didn't mark them but the OCD in me did mark them on the 18 so I can report back that both are still running strong.
