I am trying to determine why I have a gap between the last washer on the cam snout and the spacer in front of the fuel pump eccentric. I have installed the beveled spacer, retaining plate, timing gear, fuel pump eccentric, spacer, washer, and bolt, in that order.

When I move the slotted spacer behind the fuel pump concentric, only a small part of the woodruff key gets into the concentric. It looks like the timing gear needs to go on a little more. I put the thicker spacer I found, and everything seems right, with the exception of the slight engagement onto the key by the fuel pump concentric.

Although I know I’m supposed to have a lock washer, I have yet to find one on any of the few engines I’ve torn apart. Should I just use a grade 8 lock washer? Or grade 5?
