Recently, our engineers completed an overhaul of a Perkins 1006 for the Welton Oil field, near Lincoln. The cost was approximately 50% of that of a brand new replacement set. (You can read more about this story on the S-T Diesel & Marine news page). We have also uploaded a video of this engine starting up to our group YouTube channel.
