| Clanking noise after pulley install
A few hundred miles ago I had an M7 supercharger pulley install at a local mini ship.
I now have a loud clank, clank, clank coming from the tensioner/belt with black (rubber) dust on that side of the engine!
Has anyone experienced this before.......whats the fix?
The car has 6K miles, the original belt was used, the pulley bolts, tensioner bolts are tight and the belt looks to be riding in the middle of the pulley although a few mm side-to-side movement while running.
Any thoughts or help appreciated. |
