rtg143, thanks for the info. Now, when I reassemble do I repeat the operation or just turn the pinch bolt so I can get to it? The part is in town but won't be delivered until Monday. Also, is the pinch bolt under a rubber cover or just above it. Sorry, but without the part in front of me I'm trying to get an image of what I'm looking for. I'm sure it will be clearer once I get it in the air and see the part. Thanks again.
