Not sure if it matters but I was backing up a few feet and thought I heard a noise. Put it back in drive no problem went about 10 ft less than 5 mph and heard metal bounce through the belt/clutch/ I took off the side shield and found a ~half inch snap ring laying under my driven clutch. It was badly bent and looked like it was forced off of the groove it was in, also it is the style that goes around the pin it was on. We looked all over and cant seem to find its home. Sled runs and moves fine forward and reverse. Any ideas?????? Thanks!!!
