They said no problem & helped me out. The salesman transferred me to a rebuild mechanic named Jeff , he watched the video & said he would check with another builder & call me back. He called back & said they have seen 1st gears with 1 ring but never 2. The rubber does belong in the groove & they believe the rings are for reducing chatter between the gear & main shaft. As far as orientation he said the single rings have 4 teeth & they are are set on the ring with 2 @ 12 o'clock & 2 @ 6. So that's how I installed the 2 rings in mine. As far as install I just took my time & worked the ring into the groove & slowly tapped the gear on the main shaft with a plastic hammer. Jeff spent at least 40 minutes on the phone with me & answered other questions for me as well. I have another 420 to rebuild & will definitely get all my parts from them. Novak SM420 link See ya!
