Where is the allen screw for priming the oil pump?
Just changed the oil along with removing the oil pain and changing the gasket. However I need to prime the oil pump now. I've been reading that there is an allen screw on the left side but I can't see it. Does anyone have a picture where I should be looking?
Thanks in advance.
Thanks in advance.

Re: Where is the allen screw for priming the oil pump?
Shawn, the allen screw is behind the hydraulic lines. I usually stick a screw driver between the lines and turn it to spread the lines to see it. You can also prime it through the filter housing using the hole found near the top inside of the housing.
There are two ways to get enough Cubs. One is to continue to accumulate more and more. The other is to desire less.

Re: Where is the allen screw for priming the oil pump?
Left rear of the engine block, under the hydraulic lines as Bill reports. Usually stuck tight and unable to remove it.
Easiest is to use the opening inside the oil filter housing, towards the front of the engine and down about an inch. Put about 1/2 cup engine oil into the opening.
You may not need to prime the oil pump if the engine has been recently run. However, it's good insurance to do so.

I have an excuse. CRS.

I ran the engine for about 10 minutes prior to changing the oil to warm it up a little this evening.

Re: Where is the allen screw for priming the oil pump?
Hi,
Here is a picture of where the hole is, just remove the oil filter top, and it is easy to see, use a light if you need to.
I fill a clean oil can with motor oil, and pump it into the hole, you might need more than one filling of the oil can to fill the passages in the engine.

That old picture I took of the filter housing sure gets around better than I do these days.

Re: Where is the allen screw for priming the oil pump?
If you look closely at the upper left corner of Barnyard's picture, there is an allen head screw that can be removed and the passage can be used to prime the pump BUT as Eugene said it is usually stuck and unable to remove it. The easiest way is to do like Glen said and prime through the hole inside the filter housing while the housing top is off.

Re: Where is the allen screw for priming the oil pump?
Hi,
I didn't know it was your pic Bill, I got it from a post after I searched for a pic, I think. I don't think it was on a post from you, but not sure. Hope it's ok to use the pic.
I wanted to take a pic of my Cub there, but can't with the hood on, the side of the hood is in the way.

You are most welcome to use it. That's why it's out there. I'm glad to see it get a lot of use.

On the 57 Loboy there is a allen head plug on the outside of the block at 2:00 position of filter cover, or just above on the hole as in the picture , is that the same priming hole?

Re: Where is the allen screw for priming the oil pump?
If all he did was change oil pan gasket and oil, i don't see any reason to prime the oil pump. Engine was run to warn up oil before draining.

Re: Where is the allen screw for priming the oil pump?
I have never had to prime one except after a major tear down, but that does not mean it would never have to be done otherwise. When I do prime one I remove the spark plugs and pump oil into the hole in the side of the filter housing and then spin it with the starter till I see oil start squirting out the hole then put everything back to normal and start it. Sometimes if it is a little slow to start pumping I will use my 12 volt jumper box to increase cranking speed. Remember, 20 to 40 seconds before oil pressure comes up is to be expected on a normal start up, especially after an oil change since the filter housing is empty and you do not see pressure on the gauge till it is full.
If you are not part of the solution,
you are part of the problem!!!

Wish I tried your method but I worked on the Cub before I read your post, I did crank the motor a bit to see if the gauge registered pressure but it did not that said I think its a go for tomorrow just need some gas line and a remote tank and then
