Healthways Plainsman BB Pistol Disassembly, Part 2

On I go…

11041121
The power adjuster and spring that connects to the hammer.

11041122
The power adjuster has three discrete notches around the periphery.

11041123
Which mate with the molded pin sticking out of the channel.

11041124
The CO2 cartridge chamber and valve assembly.

11041125
Notice the flat face of the exhaust valve.

11041126
The flat face sits against the o-ring and gas travels through.

11041127
What the heck, let’s call this a sear.

11041128
Just a flat bar with a dogleg.

11041129
Notice the spring on the hammer passes above the pin in the BB feed mechanism in front and below in the back (relative to the orientation of the pin…)

11041130
When the trigger is pulled it move the feed mechanism up.

11041131
The trigger and spring.

11041132
The hammer. 

11041133
It has a steel insert.

11041134
A large nut for the piercing cap sits in the frame casting.

11041135
Right frame has three screws that are removed.

11041136
And the BB feed mechanism comes free.

11041137
Huh, a flat rubber gasket.

11041138
It was glued (probably with rubber cement of some sort) to the frame.

11041139
This is another first, the passage for the gas as it travels from the valve to the barrel is open on the side. The gasket seals it against the frame.

11041140 
The barrel slides out. The barrel seems to be copper tubing but I suppose it could be bronze.
More to come…
