I recommend you to delete the extraction tool ID. Also deburr the front edge. The tool fits snugly onto the switch shaft. It is designed to be screwed into a seal. When tying you have to exert internal pressure. It goes down when full. I used a 3/8 ratchet and socket. Worked great. A YouTube video showed him being hit with a hammer. It's not mandatory. The tool also did not have to be provided. I don't know what kind of trance this guy was working on. I smeared some grease on the pivot pin. but probably not necessary. The seal that came with the tool is of poor quality. I noticed that the rubber on the seal and shaft had cracked, even with a little bit of synthetic lube. I ordered AC Delco, there were no problems. AC Delco also had a better quality metal case. The assembly tool also sits precisely on the shaft. The seal falls as far as it will go. I used a small jackhammer. A vise was used to help slide the adjustment tool off the switch shaft. The installation tool probably needed cleaning, cleaning and lubrication. In general everything is fine. I've seen Napa sell the same tool for less than $10 (not including the print). However, I did not call to confirm this price.
