This video (towards the end) should help: http://www.youtube.com/watch?v=A80n7zq80n8 . Jon
February 5, 201115 yr it will be the top hat thats broken.will have to take the clutch cover assy of and you will find it in there.a common fault if you hit the gear lever hard with a rock.

You probably mean the centering spring bushing tab broken. The spring bushing (where the spring resides) really does look like a top hat though, maybe we'll have to be more specific about which "top hat" we're talking about in the future, the centering spring top hat or the servo cylinder top hat. What Ormplus refers to is the centering spring assembly that slides on the end of the shift shaft. Part of it looks like a top hat with a thin bar across the "top of the hat" that slides into a slot on the end of the shift shaft. If you are lucky, the end tabs of that bar will break off from the "hat" when the shifter takes a big hit and save damage to the shift racheting mechanism in the shift drum. I thought about, that but since there was no mention of the shifter flopping around and still able to shift one way, I assumed the centering spring was the problem. Jon

If it's that, it's a good thing as it kept the shock from being transfered to the internals in the shift drum or the shaft forks (both expensive to replace). Jon
