HOME Rebuilding A Cummings B3-2 - Page 4

Here I have the new parts inserted. Now time to lube the pins and finish putting it together.

Trigger job is finished. New Sear Spring and Keeper. Completely lubed and functioning smoothly. Next, it's time to change the spring and seals. For that I'll have to build a spring compressor.
Spring & Seals Rebuild

Here I have the barrel in the new spring compressor. I had to push the guide in a tad to get the retaining pin out.

Backing it out slowly, the spring guide came out with no problems.

You can see the spring guide here. Can you say cheap?

After taking the spring out, I had to take the trigger assembly back off so the air chamber could come out.
