Description
Overview:
The Piston Ring Set Plus 040 for Petters PH diesel engines is a Genuine Lister Petter part designed to restore and maintain cylinder sealing, compression, and oil control. Supplied as a matched set for one piston, the rings are engineered in engine‐grade cast iron for stable performance in high-temperature, high-load conditions. The "Plus 040" size indicates an oversize of +0.040 in (+1.02 mm), suitable for PH engines that have been re-bored to this specification. This set supports reliable running across plant and agricultural equipment powered by Petter PH units. It is unused old stock, so surfaces may show light tarnishing or storage marks, but function remains unaffected. Identified with HJC 11/12/13 040, it offers an OEM-standard fit and dependable service life.
Key Features:
- Genuine Lister Petter part for OEM fit and performance
