2. Upon receiving the parts, I reassembled the chuck , but it did not work properly.
3. I then disassembled the chuck again carefully gripping the compression ring, spring and ball.
4. I then reassembled the chuck placing the steel ball above the retention spring in the slot on the shaft rather than below the spring in the slot.
5. The chuck worked as designed after the second reassembly.
NOTE: I think that the video instruction you nicely provided should also include:
1. A warning that once the compression ring is released that the chuck and related parts are under pressure and should be held firmly so as not to lose any parts.
2. A note that indicates that the steel ball is to be placed above the ball retention spring rather than below the ball retention spring.
3. The second spring ( the ball retention spring ) should be named just that .
Thanks again for the ease of ordering parts on your website and the excellent video's that make repairs less daunting to the average DIY'er

All other parts came off with ease.
The most difficult part is the correct orientation of the spring that holds the ball bearing in its groove because the original spring had lost its hook so there was no references as to correct orientation.
After several searches for repair videos that showed this I discovered the ball bearing goes in first then the retention spring goes on hook portion first.
Other parts go back on easily enough except the last part (retention ring) pry apart at the opening with flat tip and pick, depress second spring and washer and feed ring into its groove. Keep your finger on this ring when feeding onto the groove or it could fly into your face.
