What Are Diesel Engine Parts?

The diesel engine is comprised of hundreds of small component parts, each providing a specific role in producing the power and torque needed for the diesel engine to perform up to the rigors of either daily driving or construction, industrial, agricultural or marine applications. Without each individual part operating to its designed capability, the diesel engine would not perform to the strict standards of the original engine manufacturer. Goldfarb & Associates offers genuine and original engine manufacturer (OEM) turbochargers, diesel fuel injectors, diesel fuel injection pumps, and spare parts including, but not limited to: nozzles, plungers and barrels, delivery valves, solenoids, pump and injector bodies, turbocharger housings, compressor wheels, turbine wheels, actuators, and more.

Where Do Our Diesel Parts Come From?

Goldfarb & Associates sources our parts from all over. From fuel injection shops, turbocharger remanufacturing shops, salvage yards, and surplus companies, Goldfarb & Associates acquires parts from trusted vendors in the diesel engine parts industry. Our inventory has been acquired from all fifty (50) states, Canada, Mexico, and over twenty (20) countries worldwide.

Quality Control and Assurance

Goldfarb & Associates has the highest quality standards in the diesel industry. When purchasing used diesel engine parts, quality has to be the single most important requirement. Every single part sent in to our Rockville Maryland facility is hand inspected and must pass a full checklist of quality criteria. For turbochargers, each turbo is inspected for wheel damage, housing damage, shaft play, and electronic connection damage. For injection pumps, each pump is inspected for damaged connections and threads, housing damage, fire and rust damage, and other physical damages. For injectors, each injector is inspected for nozzle, body, and solenoid damage. This same inspection process is applied to all new and remanufactured parts that we sell.
