The ProMAXX Rosina Tool is designed to remove broken bolts in the main turbo charger without removing it. The device bolts directly to the rear of the main turbo charger on the Ford 6.4L/International MaxForce7 diesel engine where the “Y” pipe from the exhaust system mounts. Rather than removing and replacing the turbo, users can bolt the Rosina in place and machine the old broken fasteners completely out. Now with removable and interchangeable machine grade bushings, repairs can be made quickly.
