No it should not. The injection pump cam has spline drive for the gear to the pump, this gear meshes with a smaller gear to increase pump rotation speed and the smaller gear is spline drive to the pump input shaft.

Gear9 is on a short shaft which is not shown in neither of the two links if you look at the fuel cam shaft the one end is the the gear to crankgear the other end is slotted. Gear 9 has a shaft of its own that goes in the notch on the end of the fuel cam. I decided I am going to take gear 9 out and try and see the short shaft if it broke or the cam is broken.

The gear on the splined shaft from the fuel cam feels like it is spring loaded. Turn it one way it winds up let go springs back turn the other way half a turn tightens up with in 1/2 a turn. I tried to pull shaft out but bearing will not move. Do you know if there is a spring between the cam and the splined shaft?

Well put everything back together. No hydraulics still. Is there a way to check the injector cam with out pulling the whole front end of the motor off and taking the cam out. The hydraulic pump does not turn, so I am at a loss.
