Daisy Model 188 BB Pistol Disassembly, Part 2

On I go...

The pin that retains the seal on the piston is pushed out.

There's a metal washer and a felt oil retainer inside. No worry about dieseling with the low velocity of this pistol?

A closeup of the felt and the washer.

The piston, spring and lever parts. The orientation of the linkage is important...I put it back together upside down and had to do what I show twice...

The loading port for the BBs also retains the barrel. Notice the band-aid on my thumb. The compression tube has sharp edges...

I slipped the barrel out from the front.

The parts...

You can see the channel for the BBs that leads to the bolt.

The ends of the spring were crudely ground. I polished them up.

The compression tube cap & port seal.

I polished up the piston for the heck of it. Then I used a pin punch to align everything so I could push the pin back in. The felt is a pain to get around.

I used a spring compressor to push everything together, not that the force was high but it made a good third hand.

With the cocking linkage pushed clear of the spring I reattached it to the lever. (Upside down the first time...)

My new favorite old tool...these parallel jaw pliers were just the thing to push that roll pin back in. Anyway the reast of the pistol went back together in reverse of disassembly. It's a bit weak, although I have no idea what the velocity is supposed to be. Nor do I care.

Thanks for the information. I have an old 188 that I want to recondition. What do you recommend to use for internal lubrication of this gun?

I think Daisy recommends 30 wt. oil. But whatever works. I used a light grease for some parts.
