Description
Overview:
The Delivery Valve Assy (MPN 118400-51300) is a genuine Yanmar OEM component for the high‐pressure fuel system. Fitted in the injection pump, it regulates and stabilises fuel discharge to the injector, maintaining line pressure and preventing backflow for a clean injection cut‐off. Built from durable, precision‐machined metal, it withstands continuous diesel service and the heat and vibration found in plant and industrial engines. This part is specifically engineered for Yanmar engines such as the 2V750-CVDI and 3TNV76-KWA, offering a direct replacement that restores correct fuel delivery characteristics. It helps support easy starting, smooth idle, reliable power, and consistent emissions performance across a wide range of equipment using these engines.
Key Features:
- Genuine Yanmar Part for assured fit, materials, and performance
- Precision tolerances to maintain injection line pressure and clean fuel shut‐off
- Helps cure symptoms of worn delivery valves such as hard starting and rough running
- Robust metal construction for high‐pressure diesel duty and long service life
- Direct replacement for the original valve; no modifications required
- Stable fuel metering supports power output and fuel economy
- Suited to demanding on‐site environments and daily professional use
- Manufactured to Yanmar specifications for compatibility with listed engines
Typical Applications:
Used in compact construction and industrial equipment powered by applicable Yanmar engines, including mini excavators, site dumpers, loaders, generators, pumps, and agricultural machinery. Ideal for routine maintenance or repairs where fuel delivery issues, starting difficulties, smoke, or poor throttle response suggest wear in the injection pump delivery valve.
Also known as:
Injection pump delivery valve, fuel delivery valve assembly, pump outlet check valve, high‐pressure fuel valve, injection pump non‐return valve, discharge valve for injection pump.
