Pielstick Retrofit Solutions

Our service letters share OEM guidance drawn from ongoing field experience and engineering updates—covering new developments and trends, maintenance and engine management best practices, retrofit and obsolescence recommendations, and evolving emissions and regulatory requirements.

As the original Pielstick product center and your strategic partner for Pielstick performance, these letters complement our genuine parts supply and lifecycle upgrade solutions to help keep your PA and PC series engines safe, efficient, and future‑ready.

Please note: some service letters include attachments (e.g., work cards, instructions, guidelines, specifications) that may be revised after the letter’s publication. We therefore recommend checking for the latest edition of any referenced documents before performing work.

The latest Pielstick service letters are available below. To obtain older service letters, please contact us.
