In the first post of the series, we Introduced the CZ-82 to our collection and identified the areas that needed work.
In CZ-82 Gunsmithing Part 1, we discussed the loose grips issue and disassembled the slide components.
In CZ-82 Gunsmithing Part 2, we disassembled the magazine catch and lightened the magazine catch spring tension.
In CZ-82 Gunsmithing Part 3, we removed and disassembled the safety and disassembled the slide.
In CZ-82 Gunsmithing Part 4, we removed the slide stop and spring, and then the trigger, trigger spring and trigger bar.
In CZ-82 Gunsmithing Part 5, we removed main spring, hammer, sear, and associated other fire control parts.
In CZ-82 Gunsmithing Part 6, we covered the basic trigger job.
In CZ-82 Gunsmithing Part 7, we reinstalled the hammer strut, hammer, sear, auto safety, ejector, and disconnector.
In CZ-82 Gunsmithing Part 8, we reinstalled the trigger, trigger bar and trigger spring.
In this edition, we’re going to reinstall the mainspring and cap and the safety.
The only trick with the mainspring was to be sure that the hammer strut was in the right place before putting the mainspring under tension. You can’t really see what’s going on up there with everything in place so you kind of have to do it by feel. The strut should be pretty well centered and straight in the frame to be sure that it engages the hammer properly.
Then, while keeping slight tension on the spring, I used a pick to straighten and align the hammer strut. While keeping a bit of tension on the spring, I checked the hammer operation to make sure the strut was engaging it properly. You may have to futz around with it a bit to get it just right, but it shouldn’t be too difficult.
After you’re sure the hammer strut is aligned and engaging the hammer properly, continue to keep a little pressure on the spring to hold it in position until installation is finished.
The easiest way I found to compress the spring was to put the end of the cap against my bench and then press the pistol toward it to compress the spring. Before compressing the spring, make sure the cap is turned so that the slot aligns with the pin holes in the frame.
Once the cap slot aligns with the holes in the frame, simply slide the pin into place. This pin is a loose fit, it is held in by the mainspring tension and the grips. It should not have to be driven in and put a finger under the bottom hole to keep it from dropping completely through as you slip it in.
The safety is also a fairly straightforward operation.
The first step is to install the safety latch spring. It is a very small spring that fits into a well on the right side of the safety (it looks like the left in these pictures because the safety is upside down).
Then the safety latch goes into place and presses against the spring. There will be some spring tension so be careful while installing the latch to keep it from shooting across the room. The spring especially is pretty small and would be easy to lose.
Next up, we’ll install the slide stop.
