Description
Overview:
The Lister SR1 Standard Piston Ring Set is a genuine Lister Petter component designed to restore and maintain correct sealing between the piston and cylinder on SR1 single‐cylinder diesel engines. Made from durable metal for long service life, the rings help retain compression, control oil, and support reliable starting and steady running under load. This OEM set is intended for standard (un‐oversized) bores, making it suitable for engines that remain within factory wear limits. Typical uses include plant, agricultural and industrial equipment where SR1 engines are fitted, such as generators, pumps and compressors. Supplied as unused old stock, the parts may show light tarnishing or storage marks, which do not affect function. OEM reference: 570 12140.
Key Features:
- Genuine Lister Petter OEM piston ring set for SR1 engines (OEM No. 570 12140)
- Standard size rings for un‐rebored cylinders, helping restore factory compression
- Durable metal construction for heat and wear resistance in diesel service
- Helps reduce blow‐by, improve starting, and stabilise idle and power output
- Supports proper oil control to minimise consumption and exhaust smoke
- Suitable for vintage machinery; ideal during routine overhaul or top‐end refresh
- Unused old stock: may show cosmetic tarnish only, not affecting performance
- Reliable fit when installed to specification; check end gaps and ring orientation against the service manual
Typical Applications:
Routine maintenance and rebuilds of Lister Petter SR1 engines used on generators, water pumps, compressors, small plant and agricultural equipment. Ideal when compression has dropped, oil consumption has risen, or after honing a standard‐size cylinder during a top‐end service.
