Labyrinth Rings

[rbablitz]

I'm in the process of rebuilding a 200HP HPDI and the Yamaha Service manuel states there are alignment pins for the labyrinth rings when reinstalling the crank. The book is not very clear. I looked on the crank, cylinder body, and crankcase. I can't find these alignment pins. Anybody have an idea?

There are no alignment pins for the rings. The bearings have alignment pins and the labyrinth rings are aligned by ring end gap look at the manual again it shows how to set the rings.
