5000 miles belt failure root cause

reinstall align and center that rear wheel

I understand the advice. The late model FLHTs have a axle with a fixed adjuster cam on both sides. Assuming that the geometry of the adjuster is correct on both sides, the wheel should be correctly aligned to the swingarm. If not one would expect to see some wear mark on the contact surface of the belt with the sprocket. There nothing like this. But I will recheck this before the next trip. When we did the 30 tooth pulley, we aligned the drive train using the HD alignment tool and that is even idiot proof for high level idiot like me.
But again thanks for the advice and better double check than ending up with a broken belt in BFE.
