Cblainez71,

Ok I think I have the picture now...

But let me asked, you do have the bolt in two pieces? you have separted the hammer. spring and rear shroud from the bolt housing? if yes - then

There should have been two tools supplied with the kit a knurled round cylinder type tool and a flat tool with a two progned fork on the end.

Place the knurled tool over the hammer and the spring and screw it to the shroud. Holding the knurled tool place the hammer on a solid surface and force compress the spring until the bolt housing is forced out of the shroud. You should see a groove on the bolt that the other tool will slide into and hold the spring compressed. Also the cross pin should now be exposed. Tap that pin out unscrew the old hammer and spring and replace all with the new parts provided. - then my other description should apply..
