You have to remove the engine and tear down the entire engine to remove debris and inspect for damage, more than likely it takes out the oil pumps and they are built into the case. However If you remove the driveshaft , supercharger , valve cover , loosen the chain tensioner you can remove the flywheel cover, any debris in there also will damage the stator. If you are going for it I recommend you get a manual, it tells you what you need to put it back together.
