Gamo PT-80 Disassembly, Part 4

On I go…

10021001

The Hammer mechanism is a little complex.

10021002

Notice the position of the hammer spring.

10021003

Hammer removed.

10021004

That oversaturated part is the sear? The transfer bar underneath pulls it off the hammer.

10021007

Notice the spring.

10021006

Lift it off.

10021005

The spring.

10021008

More detail of the parts, in case.

10021009

Hammer transfer unit swung into place in front of the valve stem.

10021010

Removed and the transfer bar is finally almost exposed.

10021011

Removing the valve assembly.

10021012

Now the transfer bar is free…

10021013

Headed pin pushed out through the right sideof the grip frame.

10021014

The spring is unhooked by rotating back.

10021015

Leaving this in the grip frame.

10021016

Pulling it up, careful not to lose the spring.

10021017

It’s a fairly stout spring.

10021018

Brass inserts in the grip frame.

10021019

Front view.

Plastic plugs. I’m assuming this is where a laser sight would mount on those versions that come with a laser sight.

  2. That's a heck of a disassembly... Sorry, Nick, next time I'll send you something with fewer parts!

  4. Nick:
    I recently purchased a used PT80 online. When I load a CO2 cylinder the gas all escapes from around the puncture point. There appears to be no seal or gasket of any kind around the puncture mechanism. Is a red seal or gasket missing? A diagram I have indicates a part #13810 might fit here as a seal. Is this what I need to correct the problem? Thanks for the help.

  5. It needs a seal. I don't know the part#, I just made one myself.
