31A61-01010 Nozzle Holder Assembly supports controlled diesel fuel injection for B2B excavator parts dealers, engine workshops, and wholesale buyers.
The 31A61-01010 Nozzle Holder Assembly YNF17647 is supplied as a diesel fuel injection component for compatible engine repair and maintenance applications. The nozzle and holder are assembled to support controlled fuel delivery into the combustion system, allowing reliable diesel combustion and engine response to be maintained.
Precision internal components are used because fuel injection performance depends on accurate fuel delivery under changing engine loads. When a nozzle assembly becomes worn, contaminated, or damaged, starting performance, combustion quality, power output, and fuel consumption may be affected.
For B2B buyers, the 31A61-01010 diesel injector assembly should be checked by part number, engine information, injector markings, body configuration, and existing-part photos before quantity purchasing. Accurate matching helps repair workshops and distributors reduce incorrect orders, unnecessary freight costs, and unwanted engine-parts inventory.

YNF Machinery supplies 31A61-01010 nozzle holder assemblies and related diesel fuel injection parts for machinery dealers, engine repair workshops, wholesalers, and international spare parts importers.
The YNF17647 injector assembly is intended for compatible diesel engine fuel system repair and replacement. Because nozzle and holder assemblies can appear similar while using different internal specifications or engine applications, professional buyers should avoid selecting them only by appearance.
The part number, engine information, required quantity, injector markings, and clear photos of the removed component can be provided for product confirmation before purchasing.
For distributors preparing engine-repair inventory, injector assemblies can also be sourced together with fuel pumps, filters, seals, sensors, and other diesel engine or excavator spare parts, helping multiple repair requirements be combined into one purchasing inquiry.
