The important thing is to make sure when the crank mark is correct as mentioned above. The cam mark is also almost lining up when the tang in the injector hole is visable. Or the first cyliners cam lobes are generally pointed upward. This should be confirmend by manually rotating the engine if required. Otherwise the cam and injection pump are not on the right stroke.

By manually rotating the engine at least once there is no chance of bending a valve. This just in case you really got something messed up. You probably have not as mentioned because basically the crank and injection pump have a pretty fixed relationship. That is not so with the cam.

More than a few members have messed up at this point.. It has to do with the concept of the crank turns twice and the cam and injection pump turn just once at the same time. So the relationship of the injection pump to the cam is important.

The simple check above clears this area. Easy on your type engine as you have the tang in the injection pump. This problem can arise whenever a head is sent out for work or changed. There are two separate top dead centres as far as the cam is concerned in relation to the injection pump.

Hope this is clearer than mud. Simplified the tang in the injector pump must be visable when the cam mark is fairly close to it's refferece mark. Not right on as the cam is seven degrees off when the tang is visable. This is half of the degrees the bottom crank refference is showing . First cylinder cam lobes pointing more or less upward and not downward is enough of a check when the tang is visable as well.
