That's what I'd expect. So if belt tension is a cause of this failure, wouldn't that make it more likely for the belt to fail (due to unwarranted movement from lack of tension) rather than break the metal camshaft pulley?
I'd have thought the metal camshaft pulley was more likely to be the failure from an over tensioned belt causing metal fatigue over time?

The manual does make mention of only undoing the cam pulley bolts by no more than 2 turns each

I wonder if that has anything to do with it, possibly an uneven load in an unexpected direction during a belt change Question

Out of interested, when readjusting the tensioner post initial rotations after installation, are you finding the tensioner has moved to a position where it has increased or reduced tension on the belt?


JLR utter nonsense.

The adjustment on the tensioner is merely to ensure that the spring slack of the tensioner is taken up. After that, any slack is automatically taken up by the tensioner spring, so that belt tension remains constant for the entire life of the belt.

It's merely poor design or poor manufacturing quality of the tensioner-pulley system.
