I'm not familiar with the terms so bare with me.

The bb gun will not shoot a bb.

The lever will cock the spring but the plunger part inside the barrel does not retract when the lever cocks the gun. If I stick a dowel into the barrel I can push the plunger down. When the trigger is pulled the plunger extends into the barrel with what seems the right force. It will shoot the dowel out of the barrel. On re-cocking the gun the plunger does not retract. It can be pushed down into place though.

I oiled through the oiler hole but it looks like that only gets the spring. I oiled through the output of the barrel into the barrel onto the plunger and worked the lever several times (the stock was off so no spring on the trigger). The plunger area got well lubed but still did not change resistance much if at all. Getting the plunger back into position still required a fair amount of force from the dowel.

At some point possibly a bb jamed and after firing bent the plunger part so it won't run freely in it's holder. Not positive, just guessing.

The gun is stamped and I think the spring and internals stamped together so I'm not sure if there is some way to get the spring and plunger out to see if there is a way to fix the problem.

The question is if there is some way to fix the plunger so it's free enough to work properly?

Any help would be appreciated.

I'm sorry, i do not know know how to help you, but Welcome to the Forum.

Hi Squirrler - thanks.

I should add to the post. I think if I hand loaded a bb into the barrel insert, cocked the lever and pushed down the plunger it would fire the bb ok. It would probably be below the usual power as the plunger is sticking for some reason but would shoot the bb. I can't figure out what to do next as the parts seem to be pressed in there without a way to get them out. ??

That plunger is normally connected to the piston. It's hard to say if yours is unfastened or just plain broke - you would have to go inside the gun to see. This might help:

Here's another resource I found when fixing my model 25. The piston should be similar:

You can see how the plunger goes through the piston seal, and the whole thing is pinned to the end of the piston rod:

Slavia,

Thanks for the post, very helpful.

The plunger may be broken so not connected to the spring mechanism. I'm hoping it's just bent and can be straightened.

I'm away for a few days so will try disassembly when I get back. Good pictures of the fixture. I'll have to try and rig something up.

In that Pyramydair blog they talk about the spring compressor needed to remove the innards. The spring is ahead of the wedge pin, so you have to rig some way to reach around the wedge from behind. On my Daisy Model 99 I used two 1/8" square X 12" long steel rods, and just rested the ends on something solid while I pushed on the barrel. The spring isn't very hefty (I would never consider doing it by hand on a springer pellet rifle).

Even though lever action Daisy's are ubiquitous, there isn't much out there on disassembly. Either make sketches or take photos so you can get it back together (and then post them here, of course!). This is good advice - I know because I always forget to do it.
