Arh yes, Sorry i meant the long one,
So from my understanding.( I am tired and not thinking 100%)
Old one is long, New supplied one is short.
You have short one fitted and to compensate for the length you have maxed out the adjustment?
First check the movement of the clutch throw out arm. If this is moving an expected distance but clutch still not working as intended.
Put the original bearing in/Buy the correct bearing.
Cheers
