The pump looks fine.That's as far as it comes apart.Remove the rubber "O" ring in the groove (jpg 7) you will get a new one in the kit. I recommend changing the pump bushing though (the bronze one right behind the front seal, jpg 002) , no matter how good it looks.
Chuck the stator up in the vise (jpg 003) with the front shaft in the jaws and scrap off the pump gasket.
Install new bushing, then front seal (wait to put it together,it will be in the master kit) and reassemble.
