First time round as the guys from Snells took the belt covers off, ball bearings fell out and rolled across the garage floor ...

That either sounds very lucky or unlucky depending on your outlook but at least it was caught (just) in time. 30,000 miles seems to be the time most people change them though.
Do you know if it was the tensioner bearings or the fixed ones that gave?
I ask because Ducati have changed the tensioner bearings from double races put on the shaft to a wider single type the same as the fixed bearing and I wonder if there’s any connection.
