Marine cylinder head stud removal

In the Marine/Offshore industry our customers require the removal of broken or seized studs from a wide range of equipment without further damage to the threaded hole. Foretract is very aware of the lost time costs incurred by ship/offshore installation operators. For this reason our equipment is designed to be operated by our experienced technicians in a fast, accurate and safe manner.

Our method of removal now involves the use of our “remote kit” that makes it unnecessary to remove any parts from the engine i.e. cylinder head or piston/liner
