Cub oil pump priming

I have recently purchased a 1949 Cub that has been sitting for about one year. I am told that I may need to prime the oil pump before I try to get it running. As I understand the pump sits above the oil level and may not have enough oil left on the oil pump parts to start the process if it has been rebuilt or has been sitting for a while. I certainly want oil pressure as soon as possible on the first cranking. I"m looking for the oil priming plug that should be 1/8" pipe plug and am having no luck until today as I was changing the oil filter. Almost under the oil filter cap close to block side I have located a plug. Could this be the place to prime the oil pump as the exploded drawings that I have been able to locate are not clear? Thank any and all.

You can also use an oil tank . Same deal as a tire air tank but you but a little ball valve on it . Fill it with about one and one half quarts of oil and no more than 30 pounds of air pressure. You can unscrew the pressure gauge and hook a hose there. Open the valve and the whole engine is now oiled! Jeffcat

just pull the plugs and take the crank and turn the engine over a few times. I bought a tractor that had set under a tree for 30 pluss yrs. When i took the engine apart there was still oil on the bearings. Just dont see what the worry is.

I agree with the residual oil point you make, But cubs will not self prime without help. Several have been ruined from lack of prime. I worked on a Subaru that was driven 10 miles at 75mph with the oil plug gone (a quick change station had not but finger tightened it) When it dumped the oil on I25 north of Denver, it produced what the owner clamed was whiteout conditions for 3 miles. Itran into the shop in Ft. Collins with all the lifters collapsed, and sounding like 75 or so 1/2" steel balls in a five gallon (steel) bucket. I put a new plug in the bottom, Primed the oil system with about five squirt cans of oil till it had pressure in the galley, and started it up. In fifteen seconds the ratteling stopped and the engine was quiet. We put a calibrated gauge on it and it was spec at 40 PSI Idle. We serviced that car for the nexxt two years without any issues, and (I believe it did not suffer) Kendall GT 10-40 oil was put in it at the quick change, and that is what we put back in it. JimN

The oil pump is located on the left rear of the engine.

There is a plug on the left side of the engine. As your are standing on the left side of the engine the plug will be to the right of the bottom edge of the manifold.

The second location. Look inside of the oil filter housing. There is a hole near the top on the inside. You can use an oil can to put oil into either location.
