180-7341 Fuel Injection Pump For CAT 3126 Engine Fuel Pump

On a CAT 3126 engine, this pump plays a central role in the HEUI injection system: it builds the high oil pressure that drives the unit injectors, which in turn determines how much fuel is delivered and when. A failing pump shows up as hard starting, loss of power, rough running, engine derating or a sudden shutdown, and the longer it is left untreated the greater the risk of damage to the injectors and injection actuation system. This replacement pump restores the correct injection oil pressure and puts the engine back to full performance at a fraction of the dealer price. It is the practical repair choice for 3126 powered excavators, loaders and trucks that are otherwise in good condition.
