How do you get the check ball out from the hole in oil pump
I am trying to get the check ball out from oil pump because it dumps oil out of the crank case vent hose when you shut the engine off,I stuck a magnet down there that didn't work it seems to be down there pretty tight is that the way it suppose to be,so how are you suppose to get this ball out?Any ideas

This is a common problem with the older bikes. The reason is the position of the oil tank and the type of oil pump the engine is equipped with. With the tank being higher than the engine, oil will seep past the check ball in the oil pump and into the engine. When you fire the engine up, the oil pump cannot pump the excess oil back into the tank quickly enough and some gets blown out of the crankcase vent. If you allow the bike to sit for extended periods of time, this problem is worse. It's commonly called "oil sumping" around here. When you hear an old Shovelhead rider talking about his bike "puking", that's what he's talking about. I've seen those bikes puke nearly a quart of oil after sitting a few months. I've seen Ironhead Sportsters completely drain the oil tank into the engine. This is normal to a degree but if it gets too bad, you can "reseat" the check ball by removing the plug above the check ball on the oil pump and use a small hammer and punch to gently tap the ball into the seat in the pump. Then, remove the old ball and drop in a new one.
Oil can drain down from bag if sitting a while it drains to engine there was & maybe a check valve in the rt side rear of cam cover area. it looks like a big screw. in there is a spring then a steel ball remove & clean check ball for pits & seat area on hole. some draining is normal..ride safe..
Without knowing what make or model you have, check the following:
1. Some, not all, compressor dip sticks have venting holes for the crankcase. If the vent holes are plugged or the check ball is stuck the dip stick will get forced out when the piston comes down.
2. Make sure the oil level is where it's supposed to be. Too much oil in the crankcase will cause the motor to work harder and the excess oil being splashed around the crank case can overwhelm the vents in the case or dip stick and again blow the dip stick out.
3. Worst case, you have worn or broken rings on the piston(s), a hole in a piston or a badly scored cylinder(s) and air is leaking past the piston and creating pressure in the crank case and blowing the dip stick out.
If you look directly behind the oil pump, you'll see a line of three holes where hoses run to the engine on your Shovelhead. The top hose just above and behind the pump is the breather hose for the primary and oil tank. The next one down is the return hose for the oil that collects in the pirmary to be sucked back into the engine by crankcase vacuum. The lowest hose, and probably the one you are talking about is the crankcase vent hose.
This hose vents the crankcase pressure out of the engine. When the bike is allowed to sit for an extended period of time, oil seeps past the check ball in the oil pump and goes into the engine. This is because the oil tank is higher in the frame than the engine and the ball cannot make a complete seal. Now, the oil builds up in the engine cases. When the engine is started, the scavenger side of the oil pump cannot pump all the oil out of the cases fast enough and it's blown out of the crankcase vent. I've seen as much as a quart of oil pumped out of the cases before it stops. We call this condition "oil sumping".
Put a pan or something under the engine when you start it up. After running the engine for a while, the oil should stop. It makes a terrrible mess though. If the oil does not stop after about ten minutes of running or you get more than a quart of oil out of the vent hose, you may have a problem with your oil pump.
The best way to prevent this is to ride or at least start the engine up at least once a week. You can try reseating the check ball in the pump. Sometimes this works, sometimes it doesn't. Let me know if you need any more information.
The check ball valve is in the oil pump. When you look at the top of the oil pump, the check ball is under the innermost threaded plug, the low one, not the high one. You will have to drain the oil tank before you remove this ball. Take out the plug, the sping, and use a magnet to remove the ball. Buy two new balls, they aren't expensive.
Now, drop on of the new balls into the hole. Take a brass drift and a hammer and gently tap on the ball. This will reform the seat that the ball sits in. Remove this ball and install the other new ball, spring, and threaded plug. Refill the oil tank.
Then, remove the crankcase breather line from the rear of the air cleaner. Plug the hole in the rear plate of the air cleaner. Purchase one of the small breather filters (/V-Twin #40-0352) and put it in the end of the crankcase breather hose and relocate the breather underneath the bike.
