-I have rotated the pump via rotating the engine and the plungers move up and down. The outer barrels move up and down slightly.
-Is there something that could of dislodged inside the pump?
The forward barrel sits lower in its hole than the other three. Maybe 1/16 inch lower.
Thanks, Sam

The Outer Barrel can be removed but it has to stay with the same Plunger because they are a mated set.
In My previous Post I showed a pic of the Barrel and the Alinement Slot that when you re-insert the Barrel must belined up with a protruding pin in the Housing.
The Barrel may or may not be hard to get back in. It is going to depend on how delicate your touch is and if you dipped it in Diesel Fuel. You need to squirt or pour some Diesel Fuel on the Plunger.
If you try to use force on the Barrel to get it over the Plunger it can get stuck.
You need to get it over the Plunger and gentely and slowly twist back and forth. What you would like to happen is for the weight of the Barrel to allow it to slide down the Plunger.
Any tiny partical of dirt will bind up the Plunger and Barrel as will no Diesel Fuel on it. Motor Oil is too thick to use. Something like 3 and one, Gun Oil or Sewing Machine Oil may be thin enough to work.
If you do that try to leave the Plunger inside. On the older Pumps the Plunger can go in 2 different ways but will only work one way.
