take a large screw driver..wedge in between the opening of the shifter where it goes on the shaft..with a hammer....knock the screw driver down in between the slot..this will spread your shifting arm open enough to just pull it right off..then you cover will come right off...as helmut said..do not let the shifting shaft come out any at all..or you will have to pull the right side cover off in order to align it back up on the clutch side.
