1 466 100 325 / 1466100325 drive shaft is a 20MM VE pump drive shaft, also commonly referred to as an injection pump shaft. It serves as a critical transmission component within the fuel injection system of diesel engines. This drive shaft is specifically designed for the VE-type distributive injection pump in diesel engines. Similar to other drive shafts in this series you've previously reviewed, it is not a standard transmission shaft for general vehicle drivetrains. Instead, it is a specialized component dedicated to the fuel injection system. Its primary function is to transmit engine power to drive the VE pump, ensuring proper diesel fuel pressurization and precise distribution. During operation, it stably transmits rotational power from the diesel engine to the VE distributor pump, providing the necessary force for core functions like diesel pressurization and metered distribution within the pump. This directly influences injection timing and fuel volume, thereby ensuring stable power output and fuel efficiency for the diesel engine. It is primarily compatible with diesel vehicles and construction machinery equipped with VE-type distributor fuel pumps. Based on compatibility patterns observed with drive shafts from the same brand and series, this shaft is highly likely to match corresponding diesel engine models from Cummins, Isuzu, and others. It finds widespread application in medium- and heavy-duty trucks, tractors, excavators, loaders, and other diesel-powered vehicles and construction machinery.
