Drop this cross disc onto the 2 fingers down by the rollers. It can fit in any position. This pic is borrowed from 1stgen545’s rebuild thread.
The cam plate has matching fingers that go into the remaining recesses on the cross disc. This pic is borrowed from 1stgen545’s rebuild thread.
Here is the cam plate installed. The pin that is off center at the 3:00 position has to face the key on the pump shaft. This pic is borrowed from 1stgen545’s rebuild thread.
See the slot in the bottom of the plunger shaft at about the 8:30 position? That engages the round pin on top of the cam plate. That hardened flat washer goes in between them. Use vaseline to hold the washer in place to either the plunger shaft or to the cam plate. Either way, the vaseline will hold it in place during assembly. This pic is borrowed from 1stgen545’s rebuild thread.
The arrow is pointing at the fuel hole that has to be aligned to the key on the pump shaft. This hole can be lined up with the key or 180 degrees out. Make sure it’s lined up. This hole is in what looks like a key way. There is one on the other side as well. The side with the hole gets lined up with the key on the very front of the pump shaft. Please ignore that the small springs are in this pic as it is a disassembly pic.
This side of the collar with the shoulder and the shiny surface goes up. Note that the hole on the left side engages a ball on the governor assembly. Put vaseline into that hole. Note the ball just above my index finger to the left of the shaft.
Be careful that you use STP oil treatment on this oring. Otherwise it will get damaged like this one did when I used mineral oil. Lay the bracket onto the pump. Gently and evenly tighten all of the 4 corner screws that holds the head on. Before those 4 screws are tight, snug up the 2 allens that hold the bracket on. Then tighten them all up.
