Talk Morgan Forums Morgan Sports Cars Morgan Three Wheeler & Super 3 Super Max sprocket failure

At least it happened as I was pulling into my driveway! The neoprene sprocket came loose from the aluminum wheel which means that whatever glue was used and the various bolts have failed. The sprocket looks very good aside from being free. Hardly any wear. I am hoping that it can be reattached, or slightly worse, a new neoprene sprocket can be made for it.

Will take car to Morgan Motors of New England as they have lifts for this and I don't. I had the rear mud fender installed and it makes working on the rear more complicated and fiddly.

Well over 16,000 miles on this thing. I just rolled over 39,000 miles total last week.

Anyone else have this problem?

That is bad luck. And I thought the Supermax was the way to go. Still, 16,000 miles isn't bad.

Bad news indeed. Soon after I got mine I noticed that the little socket screws helping to hold the poly part to the alloy part were working loose. I wonder if this has happened to yours?

Really?

I opted for the new Morgan steel sprocket as it was available. While we were at it we noticed that the left muffler had cracked completely around near the forward mount and only the internal baffle was holding it together. Thought it was noisy! He had some black takeoffs so we swapped them out in less than an hour. Right side had cracks developing as well. Apparently I've more miles than anyone else so I am running into stress failures that no one has seen before!

I thought your signature brilliantly contradicted your post

Two bolts went sideways and embedded into the neoprene. Two bolts just sheered and the main bodies are still in the aluminum. The rest left. The middle of the belt has depressions in the center where all of these things are but we decided to leave the belt on as it did not effect the strength of the belt in any fashion. They asked if they should replace it but I and they felt that this was not critical. A bolt going through the outer layer where the strength is needed would be another thing. One of our members had a rock do that and it deserved a change out.

The steel sprocket is just as quiet as the Super Max. It is also more than twice as heavy! I did not detect any difference in the driving. I really don't hear the bevel box but I do hear the air from the belt as it moves it through the teeth of the front and rear sprockets. I am hopeful. The front sprocket on the bevel box is stock and merely looks polished and not worn.

As an aside, we also swapped out the left and right-hand muffler pipes as the left had cracked at the forward bracket totally around the shell and only the internal baffle was holding in on. The right had cracks starting so off it came. I was fortunate in that they had a black set of take offs that they were willing to let go of at a reasonable price (cheap!) so that was done in less than 45 minutes. All of this took place in less than four hours so I am pleased.

Another further adventure in the world of 3 wheeling...!
