Description
Overview:
This genuine Lister Petter piston (no rings) is engineered for the Lister LT industrial engine range, supporting reliable combustion, heat transfer, and power delivery in demanding service. Manufactured from a high-strength aluminium alloy and precision machined, it restores correct piston-to-bore geometry when rebuilding or maintaining LT engines. Supplied without piston rings, it lets you select the appropriate ring set to suit your cylinder condition and application. Marked with OEM number 601 50790/025, it is suitable for workshop overhauls and the restoration of older LT units often found in generators, pumps, welders, and site equipment. As unused old stock, it may show minor tarnishing from storage, but remains a genuine part designed to meet Lister Petter specifications for fit and function.
Key Features:
- Genuine Lister Petter part for assured compatibility and build quality
- OEM No. 601 50790/025 for accurate identification and fitment
- Supplied without rings, allowing correct ring choice for your bore and duty
- Precision-machined aluminium alloy for strength, heat dissipation, and low reciprocating mass
- Oversize grade clearly marked (/025) to match re-bored LT cylinders
- Helps restore compression, sealing, and efficient combustion when paired with the correct rings
- Robust construction suitable for continuous-duty and stop-start industrial use
- Designed for straightforward replacement during engine rebuilds
- Unused vintage old stock; cosmetic tarnish may be present without affecting performance
- Suitable for maintenance and restoration of Lister LT industrial engines
Typical Applications:
Used during LT engine overhauls in generators, water pumps, compressors, welders, agricultural machinery, and site equipment. Ideal for restoring performance after a re-bore, correcting wear-related loss of compression, oil control issues, or piston damage in workshop rebuilds and fleet maintenance.
