Fuel pump lifter installation

Turn the crankshaft until the flat surface of cam faces upward from the fuel pump ASSY installation hole of cam cap.
NOTE: When installing the fuel pump ASSY, since the cam convex section does not push up the pump drive surface due to the work above, the fuel pump ASSY and fuel delivery pipe NO. 2 can be installed easily.

Apply new engine oil to the pump drive cam and fuel pump lifter portion.
