I'm replacing the oil pump and pickup in my 2.2 non-turbo Sundance (87) in the next few weeks. The Haynes manual says it's as simple as dropping the pan, pulling the pump, and installing the new one. Sounded simple; an afternoon job I could easily handle. The pump arrived this week (Melling 118, IIRC), and came without any instructions. Somewhat curious about that, I started surfing the net, researching the project.
I came across one site which said I need to set #1 piston at TDC, then remove the distributor and ensure the oil pump shaft groove is parallel to the crank. This is obviously more complex than what Haynes told me the project entailed. Most sites I've viewed follow variations on the Haynes instructions.
What is the correct procedure for oil pump replacement? Also, I assume I am to leave the cotter pin in the pump? It's part of the pressure relief system?
Thanks in advance.
