Suitable for M8 Fine & M8 to M10 coarse stepped studs
For use on the steel timing belt tensioner mounting stud which screws into the aluminium cylinder head ​
The mounting studs are prone to seizing due to steel to aluminium corrosion bond which can occur between the stud and cylinder head due to oxidisation. When this occurs, the stud proves difficult to remove without the correct tool
When replacing the stud it must be torqued to the manufacturers recommended value, failure to do so can result in the stud working loose and releasing the timing belt tensioner or vibrating with the cyclic stress and snapping off. Either of these eventualities can lead to catastrophic engine damage
