once the spring and two spacers are out your going to see a gear with alignment pins inside of it with another spacer surrounding it. there are 2 pins that run down the spacer inside the pump. 1 is connected to the actual pump and the other is removable. to move the gear to the surface your going to have to tap the pulley shaft till it moves the gear up. then theres a tiny c-clip on the gear that needs to be removed. then tap out the shaft.
