Description
Overview:
The Piston Ring Set O/S 100 mm is a genuine Lister Petter part for the Lister LTI air‐cooled diesel engine. Built from wear‐resistant materials for heavy-duty service, the set replaces worn compression and oil control rings to restore sealing, reduce blow‐by, and help maintain correct oil control. Correct ring sealing improves starting, power delivery, fuel economy, and exhaust cleanliness. Sized for a 100 mm (3.94 inches) cylinder bore, this oversize set is intended for engines that require a precise refit after reboring or overhaul. It is suitable for Lister LTI engines across plant, agricultural, and industrial applications, and is supplied as a matched set to fit the designated groove widths and profiles typical to the LTI design.
Key Features:
- Genuine Lister Petter replacement for assured fit and quality
- Oversize for 100 mm (3.94 inches) bore to suit re-bored LTI engines
