yes you can get the moving vane 180 out
there is a simple way to make sure you get the moving vane in the correct way
there may have been three punch marks aligning up the shaft,big nut ,and carcass
all AC shocks have the notch in the square shaft facing to the right
all CW shafts have the notch facing to the left
many people take them apart and mix them up ,that is a big no no
the big nut MUST have the two air vents,(they are NOT plugs to hold the nut from turning) at the very top,so that one air vent is to the right of TDC and the other is to the left of TDC this allows air to vent out of the fluid,
its replenished by the little ball check valve at the bottom of the big nut
also all shocks with the check balls in the side of the stationary vane are one way valves and MUST be positioned right
look at the photo if the ball has the cage exposed on the right side its a CW shock
if there is no cage,just a hole on the right side its a AC shock
the fluid goes from the hole side to the caged ball side
the later shocks with the ball bearing on the stationary vane are self explanatory
use carb cleaner and dental picks to make sure those ball checks are free
