Topic: Oil pump replacement

[Cbled56]

Has anyone ever removed the oil pump, pickup, and drive shaft with the engine in the car? I have a 79 403 equipped T/A and would like to replace the oil pump while I have the transmission out for rebuild. Is this possible? If so, where would I find the best reference material that outlines the procedures?
Thanks!

You'd need to lift the engine to drop the pan, disconnect the exhaust manifolds, maybe distributor, perhaps any hoses or lines that are already fairly tight. Use the engine lift hook on the intake and block rear casting, unless you can bolt some mounts to the front and rear heads perhaps. Not sure if you could do it with just one engine mount unbolted, never had to do it with these.

Ok, I just spent the last few hours removing/disconnecting everything needed to remove the engine.   I was thinking about doing it with the engine in the car.  I don't see how the oil pump can be replaced with the engine in the vehicle as the procedures in the service manual states, so I will be removing the engine.  I still have 2 things left to do.  One is the power steering pump.  Should I leave the hoses hooked up and move it to the side, or disconnect the hoses and remove the pump?  The other think scares me...removing the hood.  How do I make sure I get it back on correctly?  Do I scribe a mark, use tape, other?  I would like to remove the hinges, bead blast them, paint and reinstall while the hood is off.  Wouldn't one want to paint over a scratched line and if you do, can you see the mark thru the paint when putting the hood/hinges back on.  Any and all help is much appreciated.
Thanks.
