Sachs 48mm ?hlins fggg 1082 oil volume
 

I'm a bit confused regarding oil volume. Std sachs 48 mm require about 600cc of oil in each leg and when using fggg1082 I shall only use 280cc in each leg regarding to this link https://www.ohlins.com/app/uploads/w...I_FGGG1082.pdf correct?

I suspect that is because you are going from open cartridge to closed cartridge forks. I think that would be the volume in the outer tubes. the cartridges would be full of oil

Just speculating, the info seems a bit vague where are the rest of the steps?
