Putting a motor back together and I'm stumped at something stupid. I received two 13022-45V00 flat backing plates and one 13023-45V00 backing plate with a lip on it. I can't find a picture that links which plate is which, and the manual doesn't call out which ones go where. I'm assuming the plate closest to the oil pump is a flat one. Which plate goes between timing sprocket and crank pulley, and wheres the third one go?
