Crank Pin Machining


Metalock Engineering UK Ltd have many years experience in the machining of Crankpin and Main Bearing journals in situ on engines both Large and Small for Marine Propulsion/Power or Industrial Power Generation.

We have a comprehensive range of Orbital Crankpin machines and Main Bearing machining attachments to fit all types of engines and we carry out these services everyday all around the world. Our work includes :

  • NDT Inspection - MPI and Dye Penetrant.
  • Hardness Testing.
  • Journal Fillet Radi Machining.
  • Journal Re-Grinding and Superfinishing to tolerances within manufacturers specifications

When we calculate the amount of time and man-hours involved

  • stripping down an engine to remove the crankshaft.
  • transportation to and from a machine shop for regrinding.
  • Reinstallation of the crankshaft.
  • Rebuilding of the engine.

Then total the length of time the unit is out of service or the vessel is off charter, it all adds up to a vast amount of money.

So consider a cost effective repair in situ which will minimize downtime and avoid the need for costly replacement.
