The mechanical illustration of the clutch assembly for the 30-U shows a spring that appears to hang from the clutch housing assembly (bell housing) and would be held in place by the inspection cover. It is not identified in the parts listing and you can't tell where the other end of the spring is attached from thempicture. I am thinking it attaches to the small hole in the clutch release bearing sleeve next to the hole for the clutch release bearing sleeve guide. Oddly, the spring was not on my car when I removed the clutch assembly and the hole in the clutch bearing release sleeve that goes over the guide is wallowed out, possibly because there was no spring. Can anyone confirm my suspicion and suggest a spring that would be appropriate. Thanks.
