Stuck oil pump

About two years ago, I started a project to restore my 1931 Roadster with my son and grandson. It has not run for five years. Well, life got in the way and we are starting over.

One of the things that I wanted to do is to remove and clean the oil pan as I suspected it could be pretty sludged up. We removed the pan and the oil pump should have dropped out per my Les Andrews Mechanics Handbook No. One. It did not. In fact, it doesn't even wiggle a little.

Am I missing something? What should I do? Since it appears to be stuck, I assume that it would be bad to just leave it in and replace the pan.

By the way, the oil wasn't even a little sludgy.

Thanks, Bob
 
Look at the outside of the block near the pump and make sure there is not a set screw or something like that holding the pump in place. There should be a small pipe thread plug in that hole. Good luck.

A good place to start...Here is a picture with the pump holding tool in place....

If there is something in that hole I would remove it then try again to free the pump...

The pump should come out without much resistance. If you cannot pull it out, remove the drive gear assembly by removing the large spring that holds it in place, and pulling it up and out. You can then tap out the pump from the top with a brass punch or drift.
 
Why do you want to take it out? If the only purpose of removing the pan was to clean it, put it back on with the oil pump in place.:confused:

Vermins' oil pump locating dowel was PEENED over, so the oil pump wouldn't fall on your HEAD!! ALSO, the oil pump drive had NO SPRING holding it in, BUT wouldn't budge out of the block????

I you do want to remove the pump for inspection which is a good plan if you have no idea of its condition, make sure that you put something under the pump or have a helper hold it. If it drops out and falls on the floor it could become damaged.
 
the screen can be plugged and restrict the pump. Just because the oil was clean you may miss what is under the insert. New gaskets are a good thing.
Also, the oil pump was designed to be held in position by the spring between it and the bottom of the oil pan. I have seen various methods to hold it in place, all were not as original, and I wonder if holding the pump ridigidly in position was a good thing.
several reasons to do the job right.

or someones tapped that pipe plug hole straight and the plug is now hanging up the pump. yes it should just plop out with the slightest wiggle.
