This person has probably successfully built more berkeley jets than i will ever see in my lifetime but i would strongly advise against doing it this way, especially for a novice. Instead, "Shrink fit" by placing the wear ring in the freezer and the suction piece in front of a space heater. Once the ring is below freezing and the casting is up around 100 degrees, quickly position the plastic insulator in the bore and wipe the id with soapy water or wd40. Take the ring out of the freezer and before it has a chance to warm back up - push it in the bore by hand. when the temps equalize the parts return to an interference fit. easy, and no risk of bending the ring or driving it in crooked or munching the insulator etc.

These pumps have been around for 50+ years. They were built to take abuse, unlike modern stuff. The way he installed that ring is how it’s done.
Please do a video on changing the bowl bushings - Thanks
What is the green liquid you are spraying on the wear ring to lubricate it ???
Was thinking the same thing!
