Sounds like the pin of the pivot...

point is worn out on the stamped side of the pin. Doesn't sound like the lube did that, sounds like the rim of the pin that keeps it in place is worn down.

Go to my page; "Rebuilding the B-4-2" and check the info under the photo of the 7th or 8th photo to see/read on how to fix it.http://air_guns.tripod.com/rebuilding_the_B-4-2.htm

This is a quote from that page, but it would be better if you checked out the photo, a photo tells a thousand words.

Quote; "Now here is where that orange punch with the cone shape point comes in. The cone of the punch must be wider than the cup of the pivot pin and the point must be shorter than the bottom of the cup of the pin. I had to use a grinder to give this punch the proper shape. The idea here is to bend the pivot pin cup's rim back to hold the pivot pin in place. To do this you need a flat hard metal surface to insure the other side of the pivot pin makes contact with the hard metal surface (notice I am using the flat hard surface of anvil/vise). Making sure everything is properly in place, hit the punch several times with a hammer hard in the center of the pivot pin's cup, to bend out the cup's rim. When done properly you can see that the pin is securely in place, the rim of pin's cup will cover the outer hole's edge."
