Description
Overview:
The Washer for Injector Lister Petter (part reference 751 40630) is a small but essential sealing component used on Lister Petter diesel engines to create a secure, leak-tight joint at the injector interface. Made from durable, heat- and fuel-resistant sealing material, it helps prevent fuel seepage and combustion gas blow‐by around the injector seat. This protects power output, starting performance, and emissions while reducing carbon build‐up at the cylinder head. The washer is sized specifically for injector servicing on Lister Petter machinery found in generators, pumps, compressors, agricultural equipment, and construction plant. It is suitable for routine maintenance or injector replacement tasks and is straightforward to fit when following the engine manufacturer's guidance for cleanliness and torque.
Key Features:
- Provides a reliable, leak-tight seal between injector and cylinder head to prevent fuel leaks and blow‐by
- Heat- and diesel-resistant construction for dependable performance in high-temperature engine environments
- Precisely sized for Lister Petter injector seats where this washer is specified
- Helps maintain correct injector seating for stable idle, smooth running, and easier starting
- Supports efficient combustion by reducing carbon tracking and deposits at the injector port
- Simple to install with basic hand tools during injector removal/refit procedures
- Consistent sealing crush for predictable results when torqued to the manufacturer's specification
- Suitable for preventative maintenance and corrective repairs in workshops or on site
- Compatible with common diesel fuels and typical workshop cleaning fluids
- Cost-effective replacement component that supports long service intervals and engine reliability
Typical Applications:
Used whenever an injector is removed or replaced on a Lister Petter engine, during routine servicing, troubleshooting hard starting, addressing fuel seepage, or curing combustion blow‐by at the injector seat. Common across stationary power units, generators, construction plant, irrigation pumps, and light industrial machinery powered by Lister Petter engines where this washer size is specified.
