      Hi, anybody.
      I am searching for someone (company or other) that can produce piston rings for a 1953 model NOHAB diesel. Cylinder diameter is 180 mm. The upper grooves have 5 pc compression rings. The scraper rings are a bit special. It’s two different type scraper rings in the lowermost part. The upper one of these have one solid ring whilst the lowermost groove is fitted with two scraper rings that’s half the thickness of the solid one.

      I will of course produce pics and data when/if this should lead to something.

          I have purchased rings from. A S Piston Rings , 07723918750 .

          This was some while ago so memory not too clear , but I think they are based near Chesterfield.

          Other than as a customer, I  have no connection .

          Hope they can help ! .

              Is this for one of the famed Nohab diesel locos? I suppose that they are now long out of service. Fond memories!
